摘要
紫红獐牙菜(Swertia punicea Hemsl)系龙胆科(Gentianaceae)獐牙菜属植物。分布于去南、四川、贵州、湖北、湖南等省。民间全草入药,具清肝利胆,除湿清热功效,治急性黄疸型肝炎,胆囊炎等。国内外至今尚未见有关其化学成分的报道。我们从紫红獐牙菜乙醇提取物中分得五个(口山)酮类成分,经光谱分析及化学反应,鉴定为芒果甙(mangiferin,1,3,6,7-四羟基(口山)酮-2-C-β-D-吡喃葡萄糖甙,Ⅰ),bellidifodin(1,5,8-三羟基-3-
A new xanthone glycoside, swertiapuniside (Ⅴ), has been isolatedfrom the whole plant of Swertia punicea Hemsl. The structure was elucidated as 1, 5,8-trihydroxy-3-methoxyxanthone-8-O-β-D-glucopyranosyl (1-6)-O-β-D-glucopyranoside by means of chemical and spectroscopic data. Four other known xantho-nes mangiferin (Ⅰ), bellidifodin (Ⅱ), 1, 3, 5, 8-tetrahydroxyxanthone (Ⅲ) and swerti-nolin (Ⅳ) were also identified.
