摘要
滇杨(Populus yunnanensis Dode)又名云南白杨,为杨柳科(Salieaceae)杨属植物,该属植物约有100多种,广泛分布于欧,亚、北美诸洲,我国约有62种,分成5组,滇杨属青杨组(Sect.Tacamahaca Spach)。杨属系速生树种。
Three triterpenoids (Ⅰ, Ⅱ and Ⅲ) were isolated from the roots of Populus yunnanensis Dode. which has been used as a folk remedy for the treatment of urinary tract infection and calculus in Yunnan Province.
Compound Ⅰ and Ⅲ were identified as friedelin and 21α-hydroxyfriedelan-3-one and comoound Ⅱ as 21α-acetoxyfriedelan-3-one which is a new triterpenoid. ^(13)C NMR data of Ⅱ showed that the presence of an α-acetoxy group at C-21 does not affect the boat conformation of ring E similar to the results in the study of some other D:A-friedo-oleananes.
