摘要:

运用2D NMR技术,如DQF 1H-1H COSY,HMQC,HMBC,TOCSY等,对3 个原人参二醇型双糖链配糖体人参皂甙-Rd,三七皂甙-E和七叶胆皂甙XVII的氢和碳的化学位移首次进行了全归属.

关键词: 人参皂甙-Rd, 三七皂甙-E, 七叶胆皂甙XVII, NMR全归属

Abstract:

Three protopanaxadiol bisdesmosides were elucidated as ginsenoside-Rd,gypenosi de XVII, and notoginsenoside-E on the basis of MS and NMR data comparison with  thos e in the references. The complete assignments of 1H and 13C NMR  chemical  shifts of these 3 compounds were obtained by means of 2D NMR spe ctra,such as DQF 1H-1H COSY, HMQC, HMBC and TOCSY.

Key words: ginsenoside Rd, notoginsenoside E, gypenoside XVII, N MR complete assignments
