摘要
Nagao等(1988)报道了紫菀(Aster tataricus L.f)中两个新单萜甙的结构。本文报道另一新单萜甙(1)的结构(图 1)。 4.5kg紫菀根的70％乙醇提取物,依次用苯、乙酸乙酯萃取。乙酸乙酯萃取物(40g)上硅胶柱。氯仿-甲醇(4:1)洗出物再经硅胶柱及制备薄层层析,得无色针状结晶(1)120mg。结晶(1)mp 68—70℃。
A new monoterpene glycoside named shio noside C was isolated from the root of Arter ta- taricus L. f. (Compositae). Its structure was elucidated as L-endo-camphanol-8-O-3,5-isopro- pylidene-β-D-apiofuranosyl-(1-6)β-glucopyranoside (1) by means of spectral and chemical evidence.
