摘要:

从番麻(Agave americana L.)发酵的叶汁中分离得到红光皂甙元(hongguanggenin)、Cantalasaponin-1及一个新的甾体皂苷Agameroside-1. 运用2D NMR技术,包括DQF 1H-1H COS Y,HSQC,HMBC,HSQC-TOCSY,ROESY等技术,首次全归属了3个甾体化合物的氢和碳的化学位移,并总结了红光皂甙元的甙化位移效应,从而修正了文献中部分碳信号归属以及甙元的甙化位移效应.

关键词: Agameroside-1, 番麻(Agave americana L.), NMR全归属, 甙化位移效应

Abstract:

Hongguanggenin and two hongguanggenin-based saponins, Cantalasaponin-1 and  Ag ameroside-1 were isolated from fermented leaf of Agave americana L. recentl y. On  the basis of 2D NMR techniques, including DQF 1H-1H COSY,HSQC,HMBC,H SQC-TOCSY,ROESY and so on, NMR complete assignments of  the three compounds and the glyc osylation shift effect of hongguanggenin were obtained. This led to the revision of some carbon assignments and glycoylation shift effect in the reference.

Key words: Hongguanggenin, Cantalasaponin-1, Agameroside-1,  Agave americana L, NMR complete assignments, Glycosylation shift effect
