摘要:

从三七根的80%乙醇提取物中,分离并鉴定了2 个人参皂苷类化合物,分别为6-O-(β-D-glucopyranosyl)-20-O-(β-D-xylopyranosyl)-3β,6α,12β,20(S)-tetrahydroxydammar-24-ene(化合物1)和notoginsenoside U(化合物2).应用1D 和2D NMR (1H-1H COSY、HSQC和HMBC)对这2 种化合物的结构进行解析,对化合物113C NMR 文献报道数据进行了修正与讨论,并对化合物11H NMR 数据进行全归属.同时在2D NMR 的基础上对化合物2 在氘代吡啶溶液中的1H NMR 和13C NMR 数据进行全归属.

Abstract:

Two ginsenosides were isolated from the 80% ethanol extract of the root of Panax notoginseng, namely 6-O-(β-D-glucopyranosyl)-20-O-(β-D-xylopyranosyl)-3β,6α,12β,20(S)-tetrahydroxydammar-24-ene (compound 1) and notoginsenoside U (compound 2). Their structures were elucidated by one-imensional and two-dimensional NMR (i.e., 1H-1H COSY, HSQC and HMBC) experiments. The 13C NMR spectral data of compound 1 was compared with those reported in the previous references, and corrections were made for some previous assignments which were incorrect. The completed assignments of
compound 1 were obtained. The 1H and 13C NMR signals of compound 2 in prydine-d5 were assigned.

Key words: NMR, ginsenosides, Panax notoginseng, assignment
