竹节草中酚类成分的研究

Studies on phenolic compounds from Polygomun aviculane

目的:研究竹节草Polygomun aviculane地上部分的化学成分。方法:硅胶柱色谱及薄层色谱法分离纯化,经理化性质及波谱数据分析进行结构鉴定。结果:分离得到7种酚类化合物,经结构鉴定为:迷迭香酸(1),没食子酸(2),龙胆酸5-O-(6′-O-没食子酰基)-β-D-吡喃葡萄糖苷(3),咖啡酸(4),对香豆酸(5),咖啡酸乙酯(6)和acteoside(7)。结论:化合物1,3,6,7为首次从该植物中分离得到。酚类成分的鉴定为该植物的生物活性研究提供了新的理论依据。

Objective： To study the chemical constituents from the aerial parts of Polygomun aviculane, Method： The chemical constituents were isolated by silica gel column chromatography and preparative silica thin layer chromatography, and their structures were elucidated on the basis of physico-chemical evidences and spectroscopic analysis （IR, MS, ^1H and ^13G-NMR）. Result： Seven phenolic compounds were identified as roamarinie acid （1）, gallic acid （2）, gentisie acid 5-O-（6＇-O-galloyl）-β-D-glucopyranoside （3）, caffeic acid （4）, pcoumaric acid （5）, ethyl caffeate （6） and acteoside （7）, respectively,Conclusion： Compounds 1, 3, 6 and 7 were isolated from this plant for the first time. These results provided theoretical evidences for the further bioactive investigation on this plant.
