Abstract
The invention discloses a preparation method for extracting icariin from herba epimedii. The method is characterized by comprising the following steps: a, washing, cleaning and crushing a herba epimedii medical material, crushing to 10-30 meshes, carrying out reflux extraction by 60-70% of ethanol for 3-4 hours by 2-4 times; b, combining and mixing the filtrates, suction-filtering, decompressing, concentrating and recovering ethanol to obtain a primary extract, and then washing by 80-90% ethanol and purified water and recovering; c, extracting, standing and suction-filtering the primary extract to obtain a coarse extract; d, absorbing the coarse extract by a macroporous resin column, respectively eluting the macroporous resin column by 20-30% ethanol, 50-60% ethanol and 70-80% ethanol, combining and mixing the elutants and suction-filtering; e, drying the suction filtrate to obtain product icariin. The method provided by the invention has the advantage that the icariin is convenient and rapid to extract, the raw material is abundant in source, the production cost is low, the separating effect is remarkable, and the extraction purity is high.
Description
Technical field
The present invention relates to Herba Epimedii extract, relate in particular to a kind of preparation method who from Herba Epimedii, extracts icarin.
Background technology
Herba Epimedii has the effect of male hormone sample, anti-aging effects, and disease can play a role to immunity system and cardiovascular systems, has very high pharmaceutical use.Prove that through scientific research and clinical application the extract icarin of Herba Epimedii has the cardiovascular and cerebrovascular of increasing volume of blood flow, promotes hemopoietic function, immunologic function and bone metabolism, also has kidney invigorating and YANG supporting, the anti-ageing effect of waiting for a long time.In recent years, it is found that in the big right plant Herba Epimedii and contain a large amount of icarin that oneself has obtained encouraging progress therefrom to extract icarin.Icarin preparation method of the prior art, gained icarin purity is low, and the process cost is big, and extraction efficiency is not high, and preparation time is long.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method who from Herba Epimedii, extracts icarin.
The technical solution used in the present invention is:
A kind of preparation method who extracts icarin from Herba Epimedii may further comprise the steps:
A: epimedium herb is rinsed well and pulverized, be crushed to the 10-30 order, with alcohol reflux 3-4 hour of 60-70%, extraction time was 2-4 time;
B: the merging of above-mentioned filtrate is mixed, and suction filtration, concentrating under reduced pressure reclaim ethanol and obtain extract just, use ethanol, the purified water flushing reuse of 80-90% again;
C: with above-mentioned extract just extract, leave standstill, suction filtration, get crude extract;
D: above-mentioned crude extract is adsorbed with macroporous resin column, use the ethanol of ethanol, 70-80% of ethanol, the 50-60% of 20-30% to the macroporous resin column wash-out more respectively, elutriant merges and mixes suction filtration;
E: above-mentioned suction filtration thing is carried out drying, get the finished product icarin.
The mass ratio of epimedium herb powder and ethanol is 1:10-15 among the described step a.
The drying temperature of described step e is 40-60 ℃.
Advantage of the present invention is: extract convenient and swiftly, raw material sources are abundant, low production cost, and separating effect is obvious, the dna purity height.
