Abstract

Two new alkaloidal glycosides, canthin-6-one-5-o-beta-D-xylopyranosyl- (1 --> 6)-beta-D-glucopyranoside (1) and canthin-6-one-1-o-beta-D-xylopyranosyl- (1 --> 6)-beta-D-glucopyranoside (2) named ailantcanthinosides A and B, were isolated from the root bark of Ailanthus altissima. Their structures were elucidated by one-and two-dimensional (1)H NMR, (13)C NMR, FAB-MS, HRESI-MS spectra and chemical methods.

摘要

从臭椿根皮中分离出两种新的生物碱苷，分别为崖椒碱-6-酮-5-O-β-D-吡喃木糖基-(1→6)-β-D-吡喃葡萄糖苷（1）和崖椒碱-6-酮-1-O-β-D-吡喃木糖基-(1→6)-β-D-吡喃葡萄糖苷（2），命名为臭椿苷A和B。通过一维和二维氢核磁共振谱、碳核磁共振谱、快原子轰击质谱、高分辨电喷雾电离质谱以及化学方法对其结构进行了鉴定。
