仙茅的萜类化学成分研究

The study of terpeniods from Curculigo orchioides

  • 摘要: 通过各种分离纯化方法和结构鉴定手段,从仙茅的乙醇提取物中分离鉴定了6个萜类化合物. 分别为(3S, 5R, 6S, 7E, 9R)-megatigma-7-ene-3,5,6,9-tetrol (1),actinidioionoside (2),(6S, 9R)-roseoside (3),(−)-angelicoidenol 2-o-β-D-lucopyranoside (4),(−)-angelicoidenol-2-o-β-apiofuranosyl-(1→6)-β-D-glucopyranoside (5)和tetillapyrone (7R, 9S, 10R)-3-methyl-5-(4-hydroxyl-5-hydroxylmethyltetrahydrofuryl)-6-hydroxypyran-2-one (6). 这是首次报道仙茅中的萜类化合物,丰富了仙茅的化学成分.

     

    Abstract: Six terpeniods were isolated from the EtOH extracts of Curculigo orchioides by a series separation method. They were identified as (3S, 5R, 6S, 7E, 9R)-megatigma-7-ene-3,5,6,9-tetrol (1), actinidioionoside (2), (6S, 9R)-roseoside (3), (−)-angelicoidenol 2-o-β-D-lucopyranoside (4), (−)-angelicoidenol-2-o-β-apiofuranosyl-(1→6)-β-D-glucopyranoside (5) and tetillapyrone (7R, 9S, 10R)-3-methyl-5-(4-hydroxyl-5-hydroxylmethyltetrahydrofuryl)-6-hydroxypyran-2-one (6) through manifold spectroscopic means (HRESIMS and NMR). This was the first time that reported the terpeniods from Curculigo orchioides and enriched the chemical constituents of this species.
