Abstract

The chemical structures of cabenosides I-L were investigated. These are four of the 12 cucurbitacin glycosides isolated from 'Cabeça-de-negro', the roots of Caput nigri. By means of chemical analyses the structures of cabenosides I-L were elucidated as 10 alpha-cucurbit-5-ene-3 beta,11 alpha,20S,24 xi,25-pentaol [3, 25-di-O-beta-D-glucopyranoside, and 3-O-beta-D-glucopyranosyl-(1-2)-beta-D-glucopyranosyl (sophorosyl), 25-O-beta-D-glucopyranoside], and 10 alpha-cucurbit-5,20,24-triene-11-oxo-3 beta,26-diol [3-O-beta-D-glucopyranosyl-(1-6)-beta-D-glucopyranosyl (gentiobiosyl), 26-O-beta-D-glucopyranoside and 3,26-di-O-gentiobioside], respectively.

摘要

对卡贝诺苷I-L的化学结构进行了研究。它们是从黑首（Caput nigri）的根中分离出的12种葫芦素糖苷中的4种。通过化学分析，卡贝诺苷I-L的结构被阐明为10α-葫芦-5-烯-3β,11α,20S,24ξ,25-戊醇[3,25-二-O-β-D-吡喃葡萄糖苷，以及3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基（槐糖基），25-O-β-D-吡喃葡萄糖苷]，以及10α-葫芦-5,20,24-三烯-11-氧代-3β,26-二醇[3-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖基（龙胆二糖基），26-O-β-D-吡喃葡萄糖苷和3,26-二-O-龙胆二糖苷]。
