摘要：本实验通过甲醇萃取、大孔树脂吸附、乙醇-氯仿混合溶剂萃取和聚酰胺层析以及制备色谱从落地生根Bryophyllum pinnatum叶中分得槲皮素-3-α-L-鼠李糖-β-D-木糖苷。
This study investigated the separation of the effective compositions containing quercetin derivatives from the leaves of Bryophyllum pinnatun by solvent extraction of methanol, polar adsorption by porous polymetric resins, mixed solvent extraction of methanol with chloroform and polyamide chromatography. The results indicated that the yield of product containing 51.23% quercetin in the form of quercetin derivatives was 0. 2% （W/W）. Through the NMR, Mass spectrum, Infrared spectrum, we try to identify the chemical structure of the flavonoids LEF. As a result we can conclude that the chemical structure of the flavonoicls from the leaves of Bryophy Uum pinnatum is C26 H28 O15 （quercetin3-α-L-rha-β-D-xyl） , molecular weight is 580.
