| titleOfInvention | The extraction separation method of rhamnetin-3-O-β-D-6-O-.alpha.-L-rhamnosyl-D-glucose. in Flos Caraganae Sinicae alabastrum |
| abstract | The invention discloses isorhamnetin-3-O-in a kind of Flos Caraganae Sinicae alabastrum<i>β</i>the extraction separation method of-D-6-O-.alpha.-L-rhamnosyl-D-glucose., dry Flos Caraganae Sinicae alabastrum is size-reduced, reflux, extract, concentrate to obtain extract study；By extract study first through extracting a stroke section, solvent system respectively petroleum ether, ethyl acetate and n-butyl alcohol, containing n-butanol portion further by the separation eluting of polyamide phenol resin post, eluent is concentrated into without alcohol taste, regulating pH is 2 ~ 3, and cooling stands, is filtrated to get isorhamnetin-3-O-<i>β</i>-D-6-O-.alpha.-L-rhamnosyl-D-glucose.；Isorhamnetin-the 3-O-that the inventive method prepares<i>β</i>-D-6-O-.alpha.-L-rhamnosyl-D-glucose. content>80%, the method extraction ratio is high, and equipment requirements is low, production of easily magnifying, it is adaptable to industrialization produces。 |
