Detailed Description
The following detailed description of the preferred embodiments is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention, and to clearly and unequivocally define the scope of the invention.
Example 1:
firstly, preparation of alcohol extract
The schizonepeta of the invention is purchased from the Anhui Bozhou medicinal material market. Drying the materials in the sun, pulverizing, and storing in a ventilated and dry place. The extraction method of the schizonepeta alcohol extract comprises the following steps: weighing 800g of a crushed sample, soaking the plant dry powder in 5 times of ethanol, and standing at room temperature for 12 h; ultrasonic extraction is carried out for 2 h; vacuum filtering, continuously extracting for 3 times, mixing filtrates, concentrating at 45 deg.C with rotary evaporator, drying, and storing at 4 deg.C.
Secondly, bacteriostasis of alcohol extract
The bacteriostatic activity of aqueous extract and alcohol extract of herba Schizonepetae on Botrytis cinerea, Botrytis viticola, Colletotrichum viticola and Aspergillus carbonarius is determined by hypha growth rate method. The method comprises the following specific steps:
recovering the frozen strains at room temperature, picking a small amount of colonies by using an inoculating needle to a PDA-containing culture medium, and performing inverted culture in an incubator at the temperature of 25 ℃ and the humidity of 73%;
then weighing a certain amount of extract, and preparing the alcohol extract into solutions of 50mg/mL, 25mg/mL, 12.5mg/mL, 6.25mg/mL and 3.125mg/mL respectively by using sterile water. Sterile water was used as a blank control and 5. mu.g/mL carbendazim was used as a positive control. Mixing the prepared liquid medicine with PDA culture medium at a ratio of 1:9 in a sterile clean workbench to obtain culture medium with medicine, pouring the culture medium with medicine at concentrations of 5mg/mL, 2.5mg/mL, 1.25mg/mL, 0.625mg/mL and 0.3125mg/mL into a culture dish with diameter of 90mm, and standing for solidification.
Activating strain, uniformly perforating at the position where hyphae grow vigorously by using a sterile perforator (phi is 5mm), preparing fungus cakes, inoculating the fungus cakes onto a culture medium with the strain, inoculating one fungus cake to the center of each culture dish, carrying out inverted culture in an incubator at the temperature of 25-28 ℃ and the humidity of 73% for 2-7d, measuring the diameter of the colony by using a cross method, calculating the inhibition rate, and setting 3 times for each treatment.
The results show that: the alcohol extract shows different degrees of bacteriostatic effects on 4 grape pathogenic fungi, and when the concentration of the alcohol extract is 5mg/mL, the inhibition rates on white rot pathogen, colletotrichum gloeosporioides, botrytis cinerea and aspergillus niger chartarkii are 94.57%, 70.23%, 71.15% and 20.06% respectively. The inhibitor has the best inhibiting effect on white rot germs and the worst inhibiting effect on carbon aspergillus niger germs.
