Abstract

Four new acetylated ginsenosides were isolated from the processed ginseng (SG, sun ginseng). Their structures were determined to be $3{\beta},{\;}12{\beta}-dihydroxydammar-20(22),24-diene-3-O-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-6"-O-acetylglucopyranoside;{\;}3{\beta},12{\beta}-dihydroxydammar-20(21),{\;}24-diene-3-O-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-6"-O-acetylglucopyranoside;{\;}3{\beta},{\;}6{\alpha},12{\beta}-trihydroxydammar-20(22),24-diene-6-O-{\beta}-D-6'-O-acetylglucopyranoside{\;}and{\;}3{\beta},6{\alpha},12{\beta}-trihydroxydammar-20(21),24-diene-6-O-{\beta}-D-6'-O-acetylglucopyranoside$ based on spectroscopic evidences. The compounds were named ginsenoside $Rs_4,{\;}Rs_5,{\;}RS_6{\;}and{\;}Rs_7$, respectively.pectively.
