厚叶算盘子中黄烷醇类成分的研究

Study on flavanols from Glochidion hirsutum

目的:研究厚叶算盘子的化学成分。方法:用硅胶和凝胶柱色谱进行分离,采用波谱学的方法进行结构鉴定。结果:分离鉴定了5个黄烷醇类化合物:3-O-(3-methylgalloyl)catechin(1),3-O-(3-methylgalloyl)gallocate-chin(2),3-O-galloylgallocatechin(3),gallocatechin(4),catechin(5)。结论:化合物1为新化合物,其余4个化合物均为首次从该植物中分离得到。

Objective： To investigate the flavanols from Glochidion hirsutum. Method： The column chromatographic methods were employed for the isolation and purification of the chemical constituents. The structures were elucidated by spectroscopic methods. Result： Five flavanols were isolated and identified as 3-O- （ 3-methylgalloyl ） catechin （ 1 ）, 3-O- （3-methylgalloyl） gallocatechin （2）, 3-O-galloylgallocatechin （3）, gallocatechin （4）, catechin （5）. Conclusion： Compound 1 is a new compound. The other four compounds were isolated from this plant for the first time.
