荭草化学成分的研究

Studies on chemical constituents in herb of Polygonum orientale

目的:研究荭草Polygonumorientale有效部位的化学成分。方法:采用硅胶和聚酰胺柱色谱进行分离,根据化合物理化性质和光谱数据鉴定其结构。结果:分离得到6个化合物,分别为杨梅苷(myricitrinⅠ)、木犀草素(luteolinⅡ)、没食子酸(gallicacidⅢ)、儿茶素(catechinⅣ)、原儿茶酸(protocatechuicacidⅤ)、对羟基桂皮酸(p hy droxycinnamicacidⅥ)。结论:6个化合物均为首次从该种植物中分离得到。

Objective: To study the chemical constituents of the essential substance from Polygonum oriental. Method: Compounds were isolated with silica gel and polyamide chromatography and their structures were determined by spectral analysis and chemical evidence. Result: Six compounds were obtained and identified as myricitrin, luteolin, gallic acid, catechin, protocatechuic acid, p-hydroxycinnamic acid. Conclusion: Six compounds were isolated from P. oriental for the first time.
