title: Three new dammarane glycosides from heat processed ginseng.
abstract: Three new dammarane glycosides were isolated from the processed ginseng (SG; Sun Ginseng). Their structure were determined to be 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D-glucopyranosyl(1 --> 2)-beta-D-glucopyranoside; 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D- glucopyranoside and 3beta,6alpha,12beta-trihydroxydammar-20(21),24-diene-6-O-beta-D-glucopyranoside based on spectroscopic evidences. The compounds were named as ginsenoside Rk1, Rk2, and Rk3 respectively.
