New triterpenoid saponins from Mussaenda pubescens.
Three new triterpenoidal saponins, mussaendosides O [1], P [2], and Q [3] were isolated from whole plants of Mussaenda pubescens. These structures were elucidated on the basis of chemical and spectral methods, such as their 1H-1H COSY, HMQC, HMBC, TOCSY, and NOESY nmr spectra.
