A new dammarane-type triterpene saponin from Gynostemma pentaphyllum
摘要:
One new dammarane-type triterpene saponin, named (20S)-3β,20,21-trihydroxydammar-24-ene 3-O-[α-L-rhamnopyranosyl-(1→2)] [β-D-xylopyranosyl (l→3)]-β-D-glucopyranoside (1), was isolated from the aerial parts of Gynostemma pentaphyllum (Thunb.) Makino. Its structural elucidation was accomplished mainly on the basis of the interrelation of spectroscopic methods, such as IR, HR-TOF-MS, NMR.
