From the methanolic extract of callus tissue of Rehmannia glutinosa four phenolic glycosides and one aliphatic glycoside were isolated.Two of the phenolic glycosides were identified as acteoside and forsythiaside and the structures of the other two were elucidated as 3,4-dihydroxy-β-phenethyl-O-β-D-glucopyranosyl-(1->3)-4-O-caffeoyl-β-D-glucopyranosideand 3,4-dihydroxy-O-β-D-glucopyranosyl-(1->3)-α-L-rhamnopyranosyl-(1->6)-4-O-caffeoyl-β-D-glucopyranoside.
