Abstract

Two new triterpenoid saponins named asterbatanoside D and E have been isolated from Aster batangensis and their structures elucidated as 3-O-beta- D-glucopyranosyl-bayogenin-28-O-beta-D-glucopyranosyl-(1-->6)-beta -D- glucopyranoside and 3-O-6'-acetyl-beta-D-glucopyranosyl-bayogenin-28-O-beta-D- glucopyranosyl-(1-->6)-beta-D-glucopyranoside by means of MS, 1D and 2D NMR techniques (COSY, TOCSY, ROESY, HMQC, and HMBC), and chemical reactions.

摘要

从巴塘紫菀中分离出两种新的三萜皂苷，分别命名为紫菀巴塘苷D和E，并通过质谱、一维和二维核磁共振技术（COSY、TOCSY、ROESY、HMQC和HMBC）以及化学反应确定它们的结构分别为3-O-β-D-吡喃葡萄糖基-白桦脂醇-28-O-β-D-吡喃葡萄糖基-（1→6）-β-D-吡喃葡萄糖苷和3-O-6'-乙酰基-β-D-吡喃葡萄糖基-白桦脂醇-28-O-β-D-吡喃葡萄糖基-（1→6）-β-D-吡喃葡萄糖苷。
