Abstract

OBJECTIVE

To study the contents of the flavonoids in the extract of Lespedeza virgate.

METHODS

The constituents in the ethanol extraction of the aerial parts of Lespedeza virgate were isolated and purified using column chromatography, and the isolated compounds were identified according to their physicochemical and spectral data.

RESULTS AND CONCLUSION

Eight flavonoids were isolated and identified as tricin (I), kaempferol (II), apigenin (III), kaempferitrin (IV), morin (V), luteolin (VI), quercetin-3-O-alpha-L-rhamnoside (VII), chrysoeriol-7-rutinoside (VIII). The compounds I, II, III, V and VI were isolated for the first time from the plant, and the compound VIII was isolated from this genus for the first time.

摘要

目的

研究铁扫帚提取物中黄酮类化合物的含量。

方法

采用柱色谱法对铁扫帚地上部分乙醇提取物中的成分进行分离纯化，并根据其理化性质和光谱数据对分离得到的化合物进行鉴定。

结果与结论

分离鉴定出8种黄酮类化合物，分别为小麦黄素（I）、山柰酚（II）、芹菜素（III）、山柰苷（IV）、桑色素（V）、木犀草素（VI）、槲皮素-3-O-α-L-鼠李糖苷（VII）、 Chrysoeriol-7-芸香糖苷（VIII）。化合物I、II、III、V和VI首次从该植物中分离得到，化合物VIII首次从该属中分离得到。
