More Information
Summary:The invention discloses an extraction separation method for isorhamnetin-3-O-beta-D-rutinoside in caragana sinica flower bud. The method comprises: performing crushing, refluxing extraction and concentration on dry caragana sinica flower buds, so as to obtain a crude extractive; firstly performing extraction segmentation on the crude extractive, selecting solvent systems petroleum ether, ethyl acetate and n-butanol, performing separation elution on the n-butanol-containing extraction part through polyamide phenol resin, concentrating the eluate until no alcohol smell exists, cooling, standing, and filtering to obtain isorhamnetin-3-O-beta-D-rutinoside. The content of isorhamnetin-3-O-beta-D-rutinoside prepared by employing the method is larger than 80%. The method is high in extraction rate, low in equipment requirement and easy for expanded production, and is suitable of industrialized production.
