Three novel dammarane glycosides together with six known compounds wer
e isolated from a methanol extract of the aerial parts of Gynostemma p
entaphyllum. Their structures were elucidated by one- and two-dimensio
nal NMR experiments, including H-1-H-1 correlation spectroscopy (DQFCO
SY and TOCSY) and H-1-C-13 heteronuclear correlation (HMQC and HMBC).
