Abstract

The phytochemical investigation of both chloroform and ethyl acetate extracts of Coss. & Dur. led to the isolation of a new cyanogenic glucoside 6'-methacrylate prunasin () together with seven known compounds: hydroxy-11,13-dihydro onopordaldehyde , -sitosterol , daucosterol ), nepetin (), prunasin (), astragalin () and 7---D-glucopyranosyl centaureidin (). Their structures were established by spectral analysis, mainly UV, IR, ESI-MS, 1D & 2D-NMR experiments (COSY, HSQC, HMBC and ROESY).

摘要

对 Coss. & Dur. 的氯仿和乙酸乙酯提取物进行的植物化学研究导致分离出一种新的氰基葡萄糖苷 6'-甲基丙烯酰基紫堇醇灵 ()，以及七种已知化合物：羟基-11,13-二氢吴茱萸醛、-谷甾醇、豆甾醇、新橙皮苷 (), 紫堇醇灵 (), 槲皮素 () 和 7---D-葡萄糖基芹糖基木犀草素 (). 它们的结构通过光谱分析，主要是 UV、IR、ESI-MS、1D 和 2D-NMR 实验（COSY、HSQC、HMBC 和 ROESY）确定。
