摘要
A cyclolanostene-type triterpene and two saponins derived thereform, namely MP-C,D and F,were isolated from the acid-hydrolyzate of the mixture of saponins of Mussaenda pubesecus.Their structures were elucidated on the basis of chemical and UV,IR,~1H,^(13)C NMR and MS spectral evidence.The two new saponins MP-D and F were named Mussaendoside A and C,respectively.
