title: Four new acetylated ginsenosides from processed ginseng (sun ginseng).
abstract: Four new acetylated ginsenosides were isolated from the processed ginseng (SG, sun ginseng). Their structures were determined to be 3beta,12beta-dihydroxydammar-20(22),24-diene-3-O-beta-D-glucopyranosyl(1-->2)-beta-D-6"-O-acetylglucopyranoside; 3beta,12beta-dihydroxydammar-20(21), 24-diene-3-O-beta-D-glucopyranosyl(1-->2)-beta-D-6"-O-acetylglucopyranoside; 3beta, 6alpha, 12beta-trihydroxydammar-20(22),24-diene-beta-O-beta-D-6'-O-acetylglucopyranoside and 3beta,6a,12beta-trihydroxydammar-20(21),24-diene-6-O-beta-D-6'-O-acetylglucopyranoside based on spectroscopic evidences. The compounds were named ginsenoside Rs4, Rs5, Rs6 and Rs7, respectively.
