• Gynostemma pentaphyllum (Thunb.) Makino
• Dammarane-type
• Triterpene saponin

One new dammarane-type triterpene saponin, named (20S)-3 beta,20,21-trihydroxydammar-24-ene 3-O-[alpha-L-rhamnopyranosyl(1 -> 2)][beta-D-xylopyranosyl(1 -> 3)]-beta-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.
