Abstract
The invention relates to the extraction of a natural medicament, in particular to clove leaf extract and a method for preparing the same. The clove leaf extract is characterized by consisting of the following ingredients in percentage by weight: 19.91 to 30.39 percent of syringopicroside, 32.60 to 43.18 percent of clove total flavone and total phenolic acid and 27.01 to 47.49 percent of impurity, wherein the syringopicroside and the clove total flavone and total phenolic acid account for 52.51 to 72.89 percent of the total weight of the clove leaf extract. The method has the advantages of further enriching active ingredients of clove leaf and lowering the impurity content of extract. Moreover, because macroporous adsorbent resin is used for industrial purification and ethanol solution is used for eluation, the method is low in cost, convenient to operate and environment-friendly; and the obtained products meet the requirements of medical extract.
Description
Technical field
The present invention relates to a kind of extraction of natural drug, be specifically related to a kind of Folium Caryophylli extract and preparation method thereof.
Background technology
Folium Caryophylli is the dried leaves of Oleaceae genus syringa Syringa oblata Lindl., foreign Flos Caryophylli or Korea Flos Caryophylli, and its medicinal history is long, decocting liquid treatment dysentery and ophthalmic with Folium Caryophylli among the people, and its tender leaf is used when tea-drinking can expelling summer-heat.Modern pharmacological research shows that its extract has pharmacologically actives such as tangible anti-inflammation, antiviral and hepatic cholagogic, can treat infectious disease such as bacillary dysentery, acute and chronic tonsillitis, acute/chronic bronchitis, acute gastroenteritis and acute mastitis, simultaneously can prevent hepatic injury, strengthen the excretory function of liver.
Mainly containing iridoid glycosides, phenolic acids and flavones ingredient in the Folium Caryophylli, wherein the iridoid glycoside constituents of content maximum---liposoluble ingredients such as syringopicroside and protocatechuic acid have the obvious suppression effect to staphylococcus aureus and Staphylococcus albus, the Bacillus proteus that causes secondary infection and bacillus pyocyaneus, various dysentery bacterium, Bacillus typhi and Salmonella paratyphi, the bacillus typhi murium that causes alimentary toxicosis, Salmonella etc.Phenolic acid compounds such as while protocatechuic acid have the obvious suppression effect to hepatitis B virus.Flavones ingredient in the Folium Caryophylli all has good inhibitory effect to staphylococcus aureus and Staphylococcus albus and escherichia coli.Rutin wherein has tangible resisiting influenza virus and vesicular stomatitis virus effect.
Contain impurity such as more chlorophyll, starch and polysaccharide in the Folium Caryophylli extract, these impurity do not have activity, reduce medicine antibacterial, antiviral effect, increase patient's dosage.Traditional Folium Caryophylli extracting method is the alcohol extraction of water or low concentration, and its shortcoming is that effective component extraction rate is low and impurity is more.
Be to improve drug effect, purification active site, need a kind of can be to antibiotic, the preparation technology that antivirus effective position carries out further enrichment of Folium Caryophylli.
Summary of the invention
The purpose of this invention is to provide a kind of Folium Caryophylli extract and preparation method thereof, make that contained impurity is less in the Folium Caryophylli extract, and antibiotic, effective antiviral components content is higher.

The preparation method of Folium Caryophylli extract of the present invention may further comprise the steps:
(1) Folium Caryophylli being pulverized, is the alcohol extraction of 50%-95% with percent concentration, then with extracting liquid filtering and concentrated;
(2) adding distil water in concentrated solution is placed, and is centrifugal, gets supernatant concentration;
(3) supernatant after will concentrating is handled by macroporous adsorptive resins, successively uses the pure eluting of 0-50% and 50-90%, collects the alcohol eluen of 50-90%, obtains Folium Caryophylli extract after concentrating.
Wherein, in the step (1), the standard that adds 8-15L alcohol according to every 1kg Folium Caryophylli, adding alcohol in Folium Caryophylli soaked 0-60 minute, heating and refluxing extraction or supersound extraction under 95-105 ℃ of condition then, extraction time is 1-3 time, each 0.5-2h, extracting solution is merged, and being concentrated into relative density under 50 ℃ of conditions is 1.01-1.10g/mL.
In the step (2), the volume of the distilled water of adding be the concentrated solution volume 0.5-10 doubly, placed 0-60 minute, centrifugal 0-60 minute is 1.01-1.10g/mL with supernatant concentration to relative density under 60 ℃ of conditions.
In the step (3), the rate of adsorption of supernatant in macroporous adsorptive resins is 1-10BV/h, the weight ratio of supernatant dry weight and macroporous adsorbent resin is 1: 4-1: 12, the blade diameter length ratio of macroporous adsorptive resins is 1: 3-1: 10, the volume of 0%-50% alcohol eluting is 3-8BV, quick eluting, soon valve is opened fully and is carried out eluting; The volume of 50%-90% alcohol eluting is 3-10BV, elution speed 2-5BV/h, concentrating 50%-90% alcohol eluen to relative density under 60 ℃ of conditions is 1.10-1.20g/mL, gets Folium Caryophylli extract after the drying, dry drying under reduced pressure, lyophilization or the spray drying of adopting.
Alcohol described in the present invention is methanol or ethanol, described macroporous adsorbent resin is a polystyrene type resin, comprise nonpolar macroporous adsorption resin, polar macroporous adsorption resin, middle polarity macroporous adsorbent resin, its model comprises D101, D201, HPD600, HPD200, DM130 and AB-8.
The invention has the advantages that the effective ingredient of enrichment Folium Caryophylli further, reduce the impurity content in the extract, the total weight percent of the syringopicroside of the Folium Caryophylli extract that this method prepares and Flos Caryophylli total flavones and total phenolic acid is up to 72.99%.In addition, adopt the macroporous adsorbent resin industrial purification to adopt alcoholic solution to carry out eluting usually, with low cost, easy to operate, environment is not polluted, products therefrom meets the requirement of medicinal extract.
