紫红獐牙菜极性部位化学成分研究

目的:对紫红獐牙菜化学成分进行研究。方法:采用硅胶,ODS,MCI,Sephadex LH-20 等柱层析方法进行分离纯化,根据TLC,UV,1H-NMR,13C-NMR 数据进行分析鉴定。结果:从紫红獐牙菜正丁醇萃取部分分离到6 个化合物,经波谱分析鉴定为:1,5,8-三羟基-3-甲氧基酮(I)、1,3,8-三羟基-5-甲氧基酮(II)、1,8-二羟基-3,5-二甲氧基酮(III)、1,3,5,8-四羟基酮(IV)、齐墩果酸(V)、獐牙菜苦苷(VI)。结论:化合物II为首次从该植物中分离得到。

Chemical Constituents of the Polar Part of Swertia Punicea Hemsl

Objective: To investigate the chemical constituents of Swertia punicea Hemsl. Methods: The compounds were isolated and purified by silica gel, ODS, MCI and Sephadex LH-20 column chromatography, and their structures were elucidated by TLC, UV,1H-NMR, and 13C-NMR analysis. Results: Six compounds were isolated and identified from butanol fraction of Swertia punicea extract, and they are 1,5,8-trihydroxy-3-methoxyxanthone (I), 1,3,8-trihydroxy-5-methoxyxanthone (II), 1,8-dihydroxy-3,5-dimethoxyxanthone(III), 1,3,5,8 tetrahydroxyxanthone(IV), oleanolicacid(V)and sweroside(VI). Conclusion: Compound(II) was obtained from this plant for the first time.
