摘要:

从川续断(Dipsacus asperoides C.Y.Cheng et T. M. Ai)的根中分离得到了2个三萜皂苷. 该文结合其理化性质,并通过波谱分析(ESI-MS, 1H NMR, 13C NMR,1H-1H COSY,HMQC,HMBC)鉴定了化合物1的结构为3-O-α-L-吡喃阿拉伯糖齐墩果酸28-O-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷,且报道了1H NMR谱的全归属.

Abstract:

Two triterpene saponins were isolated from the roots of Dipsacus asperoides C. Y. Cheng et T. M. Ai. The structure of compound 1 was determined by chemical and physical methods, including spectral analysis techniques such as ESI-MS, 1H NMR, 13C NMR, 1H-1H COSY, HMQC and HMBC. The compound was found to be oleanolic acid-3-O-α-L-arabinopyra-28-O-β-D-glucopyranoside-(1→6)-β-D-glucopyranoside ester. Moreover, the 1H NMR chemical shifts of the compound were assigned.

Key words: NMR, structure, 2D NMR, oleanane triterpenoids
