title: Ginsenoside Rf2, a new dammarane glycoside from Korean red ginseng (Panax ginseng).
abstract: A new dammarane glycoside named ginsenoside Rf2 has been isolated from Korean red ginseng (Panax ginseng) and its chemical structure has been elucidated as 6-O-[alpha-L-rhamnopyranosyl (1-->2) beta-D-glucopyranosyl]dammarane-3 beta, 6 alpha, 12 beta, 20(R), 25-pentol by chemical and spectral methods.
