Description
Technical field
The present invention relates to the extraction of fritillaria total alkaloids, be specifically related to the method extracting Peimine with supercutical fluid from Fritillary flower.
Background technology
The bulb of fritillary be Liliaceae (
liliaceae) Fritillaria (
fritillaria) plant, traditional medicinal part is its bulb, and the bulb of fritillary cures mainly typhoid fever dysphoria with smothery sensation, cough only gas, five viscera settling, sharp marrow, dissolving phlegm profit cardiopulmonary, has the effect such as anti-inflammatory detumescence, treatment pain furuncle poison concurrently.Nineteen eighty-two version " Chinese medicinal herbal " is stated: have " effect such as clearing heat and moistening lung, preventing phlegm from forming and stopping coughing, dissipating bind function ", clinical in phlegm heat cough, the vexed phlegm of face, controls scrofula and sore swollen toxin.The main medicinal component of the bulb of fritillary is bulb of fritillary alkaloid, comprises Peimine, verticinone etc., and bulb of fritillary alkaloid has free radical scavenging activity.From the bulb of fritillary, the method for extract total alkaloids is traditional organic solvent extraction at present, if notification number is the patent of invention of CN1146425, disclose and first the bulb of fritillary is used 95% alcohol reflux, after adding 2% salt water dissolution, use sherwood oil, ethyl acetate extraction successively repeatedly, then use chloroform extraction, obtain fritillaria total alkaloids, and then use silica gel column chromatography fritillaria total alkaloids, chloroform-methanol wash-out, obtain Peimine (C after elutriant is concentrated
27h
45nO
3).But traditional method extraction is complicated, and need repeatedly extract, extraction time is long, and extraction efficiency is low, and is using bulb of fritillary bulb as raw material, and Fritillary flower is rotted afield mostly, is not used.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly extracts the method extracting Peimine with supercutical fluid from Fritillary flower simple, the time is short, efficiency is high.
The present invention solves the problems of the technologies described above adopted technical scheme: the method extracting Peimine with supercutical fluid from Fritillary flower, and its step is as follows:
A, the air-dry rear pulverizing of the fresh Fritillary flower of being won the same day, cross 45 ~ 60 mesh sieves, obtain Fritillary flower powder, loads in supercritical extraction reactor;
B, in supercritical extraction reactor, extraction temperature is 30 ~ 50 DEG C, CO
2hydrodynamicpressure is 20 ~ 40MPa, entrainment agent ethanol flow velocity 0.2 ~ 0.5ml/min, extraction time 1 ~ 3h, obtains absorption liquid after extract methanol absorption, and wherein the extraction of 100g Fritillary flower powder is rear with 20 ~ 30ml methanol absorption;
C, absorption liquid D101 type macroporous resin chromatography column chromatography, Tomography Velocity is two column volume flow velocitys per hour, first with distillation washing chromatography column after chromatography, be washed till effluent liquid colourless, then wash chromatography column with mass percentage concentration 50% ethanol of 2 column volumes, then use mass percentage concentration 95% ethanol elution of 8 column volumes, the elutriant collecting 95% ethanol elution obtains Fritillary flower elutriant, Fritillary flower elutriant is concentrating under reduced pressure 30 ~ 50min under 450 ~ 500Pa condition, obtains concentrated solution;
D, concentrated solution 100 order silica gel column chromatographies, per hour with the acetate-methanol mixed solution wash-out of 4 ~ 6 column volume flow velocity volume ratio 17:2, collect 158 ~ 202min elutriant, concentrate drying, obtain the Peimine of white.
Compared with prior art, the invention has the advantages that the method extracting Peimine with supercutical fluid from Fritillary flower, Fritillary flower powder is in supercritical extraction reactor, and extraction temperature is 30 ~ 50 DEG C, CO
2hydrodynamicpressure is 20 ~ 40MPa, entrainment agent ethanol flow velocity 0.2 ~ 0.5ml/min, extraction time 1 ~ 3h, then use methanol absorption, then macroporous resin chromatography column chromatography is used, ethanol elution, the Fritillary flower elutriant concentrating under reduced pressure 30 ~ 50min of 95% ethanol elution, with 100 order silica gel column chromatographies after concentrated, acetate-methanol mixed solution wash-out, collect 158 ~ 202min elutriant, concentrate drying, obtain the Peimine of white.The method step is simple, and extraction time shortens, and extraction efficiency is higher, and per kilogram thunberg fritillary flower can extract Peimine about 2.3 grams, and is made full use of by Fritillary flower, improves the value of the plantation bulb of fritillary.
