摘要
两种新的齐烷三萜;2 α，3 α，24-三羟基齐墩-12-烯-28,30-二酸([结构:见文])和2 α，3 α，24,28-四羟基齐墩-12-烯([结构:见文])已从阿特罗帕(Atropa acuminata)根部分离得到。抗氧化剂对羟基苯乙基反式阿魏酸酯([结构:见文本])，β -谷甾醇-3- o - β - d -葡萄糖吡喃苷([结构:见文本])和齐墩果酸([结构:见文本])也首次从该物种中报道。结构是通过波谱研究确定的，包括二维核磁共振。
Highly oxygenated triterpenes from the roots of Atropa acuminata.
Two new oleanane triterpenes; 2alpha,3alpha,24-trihydroxyolean-12-ene-28,30-dioic acid ([structure: see text]) and 2alpha,3alpha,24,28-tetrahydroxyolean-12-ene ([structure: see text]) have been isolated from the roots of Atropa acuminata. Anti-oxidant p-hydroxyphenethyl trans-ferulate ([structure: see text]), beta-sitosterol-3-O-beta-D-glucopyranoside ([structure: see text]) and oleanolic acid ([structure: see text]) have also been reported for the first time from this species. The structures were determined by spectroscopic studies including 2D-NMR.
