摘要
从川续断干燥根中分离得到一种常春藤皂苷元型三萜皂苷(化合物1),其结构被鉴定为3-O-[β-D-吡喃木糖(1-4)-β-D-吡喃葡萄糖(1-4)][α-L-吡喃鼠李糖(1-3)]-β-D-吡喃葡萄糖(1-3)-α-L-吡喃鼠李糖(1-2)-α-L-吡喃阿拉伯糖-常春藤皂苷元28-β-D-吡喃葡萄糖(1-6)-β-D-吡喃葡萄糖脂苷,该文利用HSQC-TOCSY技术,并结合1 H-1 H COSY、HSQC、HMBC等二维谱技术对该化合物13 C,1 H化学位移进行了明确归属.
A triterpene saponins compound (compound 1) was isolated from the roots of Dipsacus asperoides C. Y. Cheng et T. M. Ai. and its structure was established as 3-0- [-β-D-xylopyranosyl ( 1-4 )-β-D-glucopyranosyl (1-4) ] [ α-L-rhamnopyranosyl ( 1-3 ) ]-fl-D- glucopyranosyl ( 1-3 ) -β-D-rhamnopyranosyl ( 1-2 ) -α-arabinopyranosyl-hederagenin-2 8-0-fl- D-glucopyranoside-(1-6)-β-D-glucopyranoside ester. This paper describes the application of HSQC-TOCSY and other techniques in the NMR assignment and structure elucidation of this compound.
