Three new dammarane glycosides were isolated from the processed ginseng (SG; Sun Ginseng). Their structure were determined to be $3{eta},{;}12{eta}-dihydroxydammar-20(21),24-diene-3-O-{eta}-D-glucopyranosyl(1{;}{ ightarrow}{;}2)-{eta}-D-glucopyranoside;{;}3{eta},{;}12{eta}-dihydroxydammar-20(21),24-diene-3-O-{eta}-D-{;}glucopyranoside{;}and{;}3{eta},6{alpha},12{eta}-trihydroxydammar-20(21),24-diene-6-O-{eta}-D-glucopyranoside$ based on spectroscopic evidences. The compounds were named as ginsenoside $Rk_1,{;}Rk_2,{;}and{;}Rk_3$ respectively.
