Abstract

Two new isoflavone glycosides, mucodianins E (1) and F (2), have been isolated from the vine stems of Mucuna birdwoodiana Tutch. Their structures have been established as retusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (1) and 8-O-methylretusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (2) by means of spectroscopic analysis and chemical methods.

摘要

从白花油麻藤的藤茎中分离出两种新的异黄酮苷，即黏油麻藤苷E（1）和黏油麻藤苷F（2）。通过光谱分析和化学方法确定它们的结构分别为刺芒柄花素7 - O - β - D - 吡喃木糖基 -（1→6）- β - D - 吡喃葡萄糖苷（1）和8 - O - 甲基刺芒柄花素7 - O - β - D - 吡喃木糖基 -（1→6）- β - D - 吡喃葡萄糖苷（2）。
