Two new triterpenoid saponins, aster-yunnanosides F and G, were isolated from the roots of Aster-yunnanensis. Their structures were determined as oleanolic acid-28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside and 3-O-beta-glucopyranosyloleanolic acid-28-O-beta-D-glucopyranosyl-(1-->6)-[alpha-L-rhamnopyranosyl-(1-->2) ]- beta-D-glucopyranoside by spectral data, especially 2D NMR analysis including COSY, HETCOR, HOHAHA, and ROESY techniques, and chemical transformation.
从云南紫菀根部分离得到两种新的三萜皂苷，紫菀云南苷F和G。通过光谱数据，尤其是包括COSY、HETCOR、HOHAHA和ROESY技术的二维核磁共振分析以及化学转化，确定它们的结构分别为齐墩果酸-28-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖苷和3-O-β-吡喃葡萄糖基齐墩果酸-28-O-β-D-吡喃葡萄糖基-(1→6)-[α-L-鼠李吡喃糖基-(1→2)]-β-D-吡喃葡萄糖苷。
