青天葵中酚性成分研究

Studies on the Chemical Constituents of Nerviliae fordii

目的:对青天葵中的化学成分进行研究。方法:采用色谱技术进行分离,运用理化性质和波谱学技术确定化合物的结构。结果:从青天葵中分离并鉴定了5个化合物,分别为鼠李柠檬素(1)、鼠李秦素(2)、鼠李柠檬素-3-O-β-D-葡萄糖苷(3)、鼠李柠檬素-4′-O-β-D-葡萄糖苷(4)和对羟基苯甲酸(5)。结论:化合物3、4和5均为首次从该植物中分离得到。

Objective ： To study the chemical constituents of Nerviliae fordii. Methods ： The compounds were isolated by silica gel and sephadex LH-20 column chromatography. Their structures were elucidated on the basis of physico-chemical properties and spectral datas. Results： Five compounds were isolated and identified as rhamnocitrin （1）, rhamnazin（2）, rhamnocitrin 3-O-/3-D-glucopyranoside （ 3 ）, rhamnocitrin 4＇-O-β-D-glucopyranoside （4） and 4-hydroxybenzonic acid （5）. Conclusion ： Compound 3,4, and 5 are isolated from this plant for the first time.
