Description
Technical field:
The present invention relates to medical technical field, be specifically related to a kind of from the Decoction of Capejasmine and Fermented Soybean method of separation and purification total iridoid glycoside and total soybean isoflavone.
Background technology:
The Decoction of Capejasmine and Fermented Soybean comes from treatise on Febrile Diseases, is made up of Fructus Gardeniae and Semen Sojae Preparatum.In side, Fructus Gardeniae is the fruit of Maguireothamnus speciosus Fructus Gardeniae Gardenia jasminoides Ellis., there is function of gallbladder promoting, short pancreatic secretion, blood pressure lowering, calmness, cooling, antimicrobial antiphlogistic effect, active component is iridoid glycoside, comprises jasminoidin, genipin-1-β-D-gentiobioside with cape jasmine, Gardenoside, gardoside, fevervine time glycosides methyl ester, deacetylate Herba Plantaginis methyl oxalate, Fructus Gardeniae thuja acid, gardenin etc.; In side, Semen Sojae Preparatum is the goods that processed through fermentation by the Chinese medicine such as mature seed and Herba Artemisiae Annuae, Folium Mori of legume soybean Glycine max (L.) Merr.; there is the effects such as anticancer mutation, preventing bone rarefaction, neuroprotective, blood fat reducing, antithrombotic, immunomodulating; main active is soybean isoflavone compounds, comprises daiazi, glycitin, genistin, daidzein, Glycitein, genistein etc.(Sun Chenghang, Mu Guangqing etc. the progress of Semen Sojae Preparatum active component. food research and development, 2006,27 (9): 157).Decoction of Capejasmine and Fermented Soybean application clinically shows that it can effectively regulate and improve the diseases such as anxiety, depression, insomnia and neurasthenia.
At present, focus mostly in the preparation for single medical material active component of cape jasmine total iridoid glycoside and the total soybean isoflavone of Semen Sojae Preparatum effective site for the preparation method of Decoction of Capejasmine and Fermented Soybean effective part group both at home and abroad, for example the applicant's Chinese patent ZL200510026144.5, publication number is CN1706860A, denomination of invention is " a kind of method with preparing total iridoid glycoside with cape jasmine fruit ", disclose one and comprised that water or ethanol water soak or reflux and prepare cape jasmine fruit crude extract, adopt again macroporous adsorbent resin respectively with a small amount of water and low-concentration ethanol aqueous solution eluting purification, after concentrating under reduced pressure, obtain the method for high-purity total iridoid glycoside.For another the Chinese patent application CN200910119135.9 of Hebei Medical University, publication number is CN101530455A, denomination of invention is " a kind of method of extracting anti-oxidation active substance from Semen Sojae Preparatum ", it is concentrated, dry that a kind of employing ethanol extraction, polyamide purifying, eluent are disclosed, from Semen Sojae Preparatum, extract the method for anti-oxidation active substance, which kind of compound the anti-oxidation active substance that this patent application is not clearly extracted is.More than study from single medical material and extract effective site, can not embody compound recipe medical material and close its impact interacting on each active constituent content and composition while decocting, cannot the reasonability of objective comprehensive reaction medicine to compatibility.
In addition, Chinese patent ZL03153151.2, publication number is CN1579463A, denomination of invention is " compound cape-jasmine salted-fermented beans total extract and preparation thereof and purposes ", disclose a kind of with Fructus Gardeniae, Semen Sojae Preparatum raw material, use the techniques such as solvent extraction method, solvent extraction, resin adsorption method to prepare compound cape-jasmine salted-fermented beans total extract, this total extract can be used for the treatment of climacteric syndrome, and has the effects such as antioxidation, anticoagulation, antitumor.But contained active ingredient in the not clear and definite total extract of this patent, particularly aforesaid Fructus Gardeniae active component-total iridoid glycoside, Semen Sojae Preparatum active component-the content of total soybean isoflavone in total extract is unknown, and the drug effect of this total extract does not embody Decoction of Capejasmine and Fermented Soybean application clinically as classics side-effectively regulate and improves anxiety, depression, insomnia and neurasthenia etc.
Therefore, there is no reported in literature separation and purification from the Decoction of Capejasmine and Fermented Soybean and obtain active ingredient--the method for total iridoid glycoside and total soybean isoflavone.
Summary of the invention:
The object of the present invention is to provide a kind of from the Decoction of Capejasmine and Fermented Soybean method of separation and purification total iridoid glycoside and total soybean isoflavone.
Main technical schemes of the present invention is: in order to improve as far as possible yield and the purity of isolating active ingredient from the Decoction of Capejasmine and Fermented Soybean, adopt total iridoid glycoside and total soybean isoflavone in the macroporous adsorbent resin separation and purification Decoction of Capejasmine and Fermented Soybean, first be to use a small amount of water elution, both can wash part water-solubility impurity off, can reduce again the effective ingredient ingredients from lossing of strong polarity, thereby improve yield; Next is according to the polarity feature of iridoid glycoside constituents and soybean isoflavone constituents, first use low-concentration ethanol (10%～30%) first to elute iridoid glycoside constituents, can reduce in soybean isoflavone strong polar component by eluting, use again high concentration ethanol (40%～80%) to elute soybean isoflavone constituents, thereby improve purity.
The invention provides a kind of from the Decoction of Capejasmine and Fermented Soybean method of separation and purification total iridoid glycoside and total soybean isoflavone, the method comprises the following steps:
