Description
Technical Field
The invention relates to the technical field of traditional Chinese medicinal material preparation and application, in particular to ligustrum robustum total flavonoids, a preparation method and application, and more particularly relates to a preparation method and application of ligustrum robustum alcohol extract, and ligustrum robustum total flavonoids, a preparation method and application.
Background
Various alcoholic beverages including white spirits, red spirits and beer have been popular with people. Proper drinking can promote blood circulation, dispel cold and dampness, relieve swelling and pain, relax muscles and tendons and activate blood, but long-term drinking of a large amount of wine can cause alcoholism and alcoholic liver injury. The alcoholic liver injury is one of the common liver diseases in China, and can be further developed into alcoholic fatty liver, alcoholic hepatitis, alcoholic hepatic fibrosis and alcoholic cirrhosis. After a person drinks a large amount of alcohol, different symptoms can appear according to the alcohol content in the body: the mild patient may have nausea, vomiting, dysphoria, incoherence, etc.; in severe cases, organ function will be impaired, resulting in slower breathing and even death. In recent years, the incidence rate of alcoholic liver injury in China is increased year by year, and the incidence rate has become a great hidden danger influencing the healthy life of people.
Roughty glossy privet (Ligustrum robustum (Roxb.) Blume) is a plant of the genus Ligustrum of the family Oleaceae and is included in the book "Chinese materia medica Miao medicine roll" (Guizhou science and technology Press, 2005) for its "heat-clearing, detoxifying and liver-protecting" effects. Broadleaf holly leaf prepared from strong glossy privet leaves is used as a beverage for clearing heat and removing toxicity, promoting the production of body fluid to quench thirst, refreshing and restoring consciousness, and dispelling summer heat and inducing diuresis in the southwest three provinces of China. The main chemical components of the ligustrum robustum comprise flavonoids, terpenoids, phenethyl alcohol and the like. Modern pharmacological research shows that the ligustrum robustum has the effects of resisting oxidation, regulating blood pressure, reducing blood fat, protecting liver, reducing blood sugar, resisting inflammation, relieving pain, resisting bacteria, resisting cancer and the like.

Further, the macroporous resin is AB-8 type macroporous resin.
The macroporous resin is also called high-molecular porous microspheres, is an organic polymer adsorbent with good adsorption performance, has a good macroporous net structure and a large specific surface area, can selectively adsorb organic matters in an aqueous solution, and has a selective adsorption function on natural compounds such as flavonoid compounds, total saponins and the like. The macroporous resin has the characteristics of high stability, safety, low toxicity, good separation effect, easy solvent recovery, regeneration and reutilization and the like, and is widely used for separating and purifying mixtures, particularly traditional Chinese medicine extracts, so that the macroporous resin is used for separating and purifying the ligustrum robustum total flavonoids.
The surface of the AB-8 type macroporous resin is a hydrophobic group, but a certain hydrophilic group is added to the framework of the AB-8 type macroporous resin, so that the AB-8 type macroporous resin is suitable for separating and purifying components with weak polarity such as flavonoids, alkaloids and the like. In order to research the characteristics of AB-8 type macroporous resin on the separation and purification of the total flavonoids of the ligustrum robustum, the research adopts experiments such as static adsorption, dynamic adsorption and the like to comprehensively analyze the adsorption performance of the AB-8 type macroporous resin. The result shows that the AB-8 type macroporous resin has good adsorption effect and desorption effect on the total flavonoids of the ligustrum robustum.
In order to obtain the optimized separation and purification parameters, the research adopts a single-factor method to investigate the concentration of a sample loading solution, the ethanol concentration of an eluent and the volume of the eluent of the macroporous resin, and the obtained optimal separation and purification conditions are as follows: using AB-8 type macroporous resin as a separation material, taking the sample concentration of the alcohol extract as 168mg/ml, taking the sample amount as 1/3BV, eluting with 8BV of water, 10% ethanol by volume fraction and 50% ethanol by volume fraction in sequence, collecting 50% ethanol eluent, and concentrating under reduced pressure to dryness.
Because the ligustrum robustum alcohol extract is not easy to dissolve in water, when the ligustrum robustum alcohol extract is prepared, part of alcohol extract is not completely dissolved in water, the measured value of the total flavone content in the ligustrum robustum alcohol extract is lower than the actual content, however, when the ligustrum robustum alcohol extract is loaded and eluted, the incompletely dissolved substances are loaded and eluted together, and the final yield of the total flavone is more than 100%.
The seventh purpose of the invention is to provide the total flavonoids of ligustrum robustum prepared by the method.
The working principle of the invention is as follows: after alcohol is metabolized in the liver, the produced excessive free radicals can excessively oxidize lipid components on the surface of a biological membrane, so that a mitochondrial membrane and a hepatocyte membrane are damaged, and AST and ALT enter blood in a large amount. ALT content is highest in liver cells, while AST is distributed in tissues such as cardiac muscle, liver, skeletal muscle and kidney. Normally, there is a significant increase in serum ALT activity as long as a small amount of ALT is released into the blood. And the AST content in serum is low, when liver cells are necrotized, ALT is released into blood in a large amount, the permeability of cell membranes is increased, and therefore the AST in cytoplasm is released into blood, and the AST content in serum is increased. AST and ALT are the most commonly used indicators of liver damage. Therefore, by measuring the AST and ALT levels in serum, the result of the pathological liver section of the experimental mouse is observed to indicate the liver disease signal.
The male mice are randomly divided into a normal group, a model group, a negative control group, a silibinin positive control group (30mg/kg) and a high, medium and low dose group of ligustrum robustum total flavonoids (LTF) according to the weight, and the administration dose is 800, 400 and 200mg/kg respectively. Except for the normal group, mice in each group were continuously gavaged with 53% ethanol (10mL/kg) for 2 weeks. Mice in the high, medium and low dose groups were given the corresponding dose of LTF solution (0.5% CMC-Na) with silybin as positive control. The mice were observed daily for fur, appetite, behavioral status, and the like. After 2 weeks of continuous administration, changes in liver, intestine and stomach were visually observed; serum ALT and AST levels of mice in each group were measured. As a result: compared with the normal group, the liver index of the mouse in the model group has significant difference (P)<0.01); compared with the model group, the liver indexes of the mice in the normal group have very significant difference (P)<0.01). Serum ALT levels were significantly reduced in the high, medium and low dose LTF groups compared to the model group (P)<0.05) ALT is obviously different because ALT is sensitive, and the ALT in serum can be greatly increased as long as liver cells are damaged. LD of LTF50>500mg/kg, indicating lower LTF toxicity. And (4) conclusion: the LTF can effectively improve the toxicity of alcohol to gastrointestinal tracts and nerves of mice, and has certain drug effect and safety on preventing acute alcoholic liver injury of the mice.
LD50The minimum drug dosage required for causing half of the death of experimental animals can be used for judging the safety of the drugs and is a safety scale for measuring the drug exposure of human beings.
The experiment adopts 53% ethanol to simulate a mouse acute alcoholic liver injury model. Due to the reduction of the food intake of the mice, the food intake required by the mice cannot be met, so that the weight of the mice is obviously reduced. The death of mice may be caused by various factors such as flatulence due to alcohol stimulation, nerve inhibition by alcohol, and intolerance to alcohol due to individual differences of mice. Late death may be due to the initial formation of acute alcoholic liver injury, which in turn leads to the development of complications associated with alcoholic liver injury.
The liver is the main metabolic point of alcohol, however, the alcohol can cause the liver to generate alcoholic liver function damage and organic degeneration, so that the liver quality is increased, and the liver index can show the formation of liver damage to a certain extent, so that the condition of liver weight increment is generated. In this experiment, it was determined that the liver index of the model group mice was slightly higher than that of the other group mice, probably due to the formation of fatty liver, resulting in an increase in liver mass.
Acute toxicity refers to a toxic reaction, including a lethal effect, which occurs in a short period after a human or an animal is contacted with an exogenous chemical once (which means that the toxicity of the exogenous chemical is too low and the exogenous chemical needs to be given to the animal in a large dose) or for multiple times within 24 hours (which means that the toxicity of the exogenous chemical is too low and the exogenous chemical needs to be given to the animal). The acute toxicity test is carried out on the medicine, aims to provide reliable scientific basis for the toxic action of the medicine in a short time and the clinical diagnosis, prevention and emergency treatment of the medicine. In the preliminary experiment, mice were gavaged several times within 24h at doses of 5, 50, 500, 5000mg/kg of LTF, and did not die. Therefore, the test results of the preliminary test and the data on the Ligustrum robustum recorded in the "Chinese materia medica seedling medicated roll" were combined to carry out the actual tests with the dosage of 200mg/kg, 400mg/kg and 800 mg/kg. The experimental result shows that the LTF has certain safety and does not cause the death of mice and other abnormal changes.
LD50The minimum drug dosage required for causing half of the death of experimental animals can be used for judging the safety of the drugs and is a safety scale for measuring the drug exposure of human beings. The larger the LD50, the lower the toxicity of the drug, the safer; otherwise, LD50Smaller indicates more toxic and dangerous drugs. Most of the traditional Chinese medicinal materials have mild effects and low toxicity, and LD cannot be measured50. In the experimental process, after the mice are perfused with the LTF, no abnormal reaction and death phenomenon occur in each dose group, and LD (laser diode) exists50>500mg/kg, which preliminarily shows that the LTF belongs to low toxicity grade and has higher safety.

In the optimization of the dynamic analysis conditions, a single-factor method is also adopted, the eluates with different ethanol concentrations are collected, the absorbance is measured, and the total flavone concentration in the eluates is taken as the ordinate and the ethanol concentration is taken as the abscissa for plotting, as shown in fig. 3. It can be seen that, when the concentration of the eluent ethanol is 30%, the concentration of flavone in the eluent is at most 94.51mg/ml, when the concentration of the eluent ethanol exceeds 50%, the concentration of total flavone of the ligustrum robustum in the eluent begins to decrease, and the concentration of total flavone is lower when the concentration of the ethanol is 70%; concentrating, drying and weighing the eluents with different ethanol concentrations to obtain total flavone part extracts with different ethanol concentrations, and plotting the total flavone part extract mass as ordinate and the ethanol concentration as abscissa, as shown in fig. 2, when the ethanol concentration of the eluent is 50%, the total flavone part extract is the most, the ethanol concentration is lower when the ethanol concentration is 70%, and the cumulative percentage of the extracts exceeds 91.2% when the ethanol concentration is 60%. Therefore, the optimal eluent concentration is most suitable to select 60% ethanol by comprehensive consideration.
3.2.3 validation experiments
By combining the experimental results, the optimized AB-8 type macroporous resin conditions for separating the total flavonoids of the ligustrum robustum are as follows: collecting 2800ml AB-8 type macroporous resin, loading the ethanol extract of Ligustrum robustum with concentration of 168mg/ml, standing for adsorption, eluting with water, 10% and 50% ethanol sequentially, each gradient is 8BV, collecting 50% ethanol part, concentrating, and drying to obtain Ligustrum robustum total flavone part. The extract yield was 53.4% and the flavone content was 44.5% (see table 4). The identification shows that the fluorescent substance shows gray yellow under visible light and yellow fluorescent spot under ultraviolet light.

3.2 pharmacodynamic Activity of Ligustrum robustum Total Flavonoids on acute alcoholic liver injury
3.2.1 dose Range findings
Research shows that the daily dose of the ligustrum robustum is 10-15 g, the dosage of the ligustrum robustum converted into the LTF is 1.3-2.0 g according to the separation and purification yield of the LTF, and the administration dose of the mice is 303.7mg/kg according to 60kg of the weight of an adult. To investigate the safety and maximum dose of LTF, the dose range of LTF was examined.
According to the method of item 2.3.3, the mice were good in physical condition, had a normal diet, were free from movement, had glossy hair, and had no phenomenon of death (survival rate: number of mice surviving/total number of mice × 100%) after being administered with different doses of total flavonoids of ligustrum robustum. The total flavonoids of ligustrum robustum are shown to have certain safety within the dosage range of 5-5000 mg/kg (see table 5).
Table 5: acute toxicity pretest mouse survival
The body weight change trend was not significant in the mice of each group in the dose study (see FIG. 4). Indicating that the effect of different doses of LTF on body weight changes in mice falls within the normal range.
The morphology of the liver of mice in each dose group of LTF was observed, and the liver of the mice was reddish brown, smooth and glossy, and had no inflammation (see FIG. 5). Indicating that LTF did not adversely affect the liver of the mice.
3.3 acute alcoholic liver injury model Observation
Compared with the normal group, the mice in the model group all appeared in a drunken state after being perfused with 52% alcohol (10mL/kg), and were slow in movement and teeter, and were drowsy, sleepy, slow in breathing, reduced in food intake, lusterless in hair, and even had a creaking sound. After one week, the survival rate of the model group mice was 20.0%, and the survival rate of the normal group was 100.0% (see table 6).
Table 6: survival rate of mice with acute alcoholic liver injury
In the experimental process of establishing the acute alcoholic liver injury model, compared with the initial weight, the weight of the model group mouse changes more obviously than that of the normal group mouse, and is in a greatly reduced trend (see fig. 6).
During the alcohol molding process, the dead mice are subjected to a autopsy, and the phenomena of extremely severe flatulence in the intestines and the stomach, a small amount of yellow mucus in the intestines and no content in the stomach can be observed visually in most of the mice (see fig. 7). It was shown that mice developed acute alcoholism and the organs were damaged.
3.4 pharmacodynamic test of Total Flavonoids
In pharmacodynamic experiments, all mice in the normal group had normal conditions, diet, activity and food intake, and had glossy hair. After the other groups of mice are subjected to gastric lavage with alcohol, the mice are drunk, and the mild mice have slow movements and unstable walking, and the severe mice have drunk, sleepy, slow breathing, reduced food intake and lusterless hair.
Except for the survival of all normal groups, 12 patients died in all the other groups due to intestinal flatulence and flatulence caused by alcohol stimulation, alcohol intolerance, alcoholic liver injury poisoning related complications and the like, and the survival rate of the normal group is 100%, and the survival rate of the other groups is shown in table 7. The results show that LTF significantly reduces mortality in mice. Calculated according to the modified Karber method, LD50817.5mg/kg, greater than 500mg/kg, so LTF is of low toxicity grade.
Table 7: pharmacodynamic experiment mouse survival rate
The pathological section results of mouse liver show (see fig. 8) that normal mouse liver cells are complete in structure and similar in size, have large and circular or elliptical nuclei with lobular central veins as centers, and have uniform cytoplasmic staining without liver lesions. The liver lobules of the model group mouse and the negative control group mouse are not clear, the liver cell cord is disordered, the liver sinuses are narrowed, the liver cells are obviously swelled, and part of the area is infiltrated by ballooning and inflammatory cells, so that the liver is obviously damaged by alcohol. Compared with the model group, particularly the high dose group (800mg/mL), the positive control group and the LTF different dose group have the advantages that the hepatocyte swelling is obviously reduced, the cell nucleus is further normalized, and the liver tissue of the mouse is repaired to a certain extent. Meanwhile, the weight changes of the mice in each group before and after the experiment are compared, and the weight of the mice in each group is found to be in a descending trend compared with that of the mice in a normal group (see figure 9). The weight change of the normal group of mice is stable, the weight of the model group of mice is continuously reduced (4 +/-1 g), and the weight change trends of the rest groups of mice are the same and accord with the growth and development rules of the mice.
Compared with the normal group, the liver index of the model group mice is significantly increased (P <0.01), and the LTF dose groups have no significant change (see Table 8). The results show that LTF has a certain relieving effect on the pathological changes of the liver of the mice given alcohol.
Table 8: effect of Ligustrum robustum Total Flavonoids on mouse liver index
Note: in comparison with the normal group,**P<0.01; in comparison to the set of models,##P<0.01。
the ALT and AST level measurement results in the mouse serum show that the ALT level of the model group, the negative control group and the positive control group is higher than that of the normal group, and the ALT level of each LTF dose group is obviously lower than that of the normal group (p <0.05) (see figure 10). The AST levels in the positive control, LTF dose groups were comparable to the normal group, with each of the remaining groups being slightly higher than the normal group (see FIG. 11). The results show that a mouse liver injury model is formed initially.
ALT and AST levels of the model group and the negative control group are higher than those of the normal group. ALT was significantly increased in the negative control group compared to the normal group (P < 0.01); compared with the model group, the ALT levels of the LTF high, medium and low dose groups were statistically different (P <0.05), and the AST level was not significantly different (see Table 9). The results show that LTF can effectively prevent the formation of acute alcoholic liver injury and prevent the further development of liver injury.

Note: in comparison with the normal group,*P<0.05,**P<0.01; in comparison with the set of models,#P<0.05,##P<0.01。
the experimental result shows that the LTF has higher safety and certain drug effect on mice with acute alcoholic liver injury, and has no adverse effect on the appearance, behavior state, visceral organs and the like of the mice. The LTF can effectively improve the stimulation of alcohol to the gastrointestinal tract and nerve of mice, and has a certain drug effect on the prevention of acute alcoholic liver injury of the mice.
