摘要
A new natural diterpene glycoside was isolated from Aster ageratoides Turcz.Its structure was elucidated by means of IR, MS (FAB, EI), NMR ( 1 H , 13 C , DEPT), 2D NMR ( 1 H 1 H COSY, 13 C 1 H COSY, J resolved, CoLoC) spectra and chemical method as 16β,17 dihydroxy (-) kauran 19 oic acid β D glucopyanosyl ester.
