摘要: 从粘叶莸(Caryopteris glutinosa Rehd)地上部分的乙醚萃取物中分得一新二萜酸——粘叶莸酸(glutinic acid),其结构经IR,UV,MS,H1-NMR,13C-NMR,DEPT和13C-1H COSY分析确定。Abstract: A new diterpenoid compound named glutinic acid has been isolated from Caryopteris glutinosa Rehd by liquid chromatography on Al2O3 and silica gel column. The structure of glutinic acidwas elucidated on the basis of IR, UV, MS, H1-NMR, 13C-NMR, DEPT and 13C-1H-COSY spectralanalyses.
