Abstract
Two glucosides were isolated from the roots of Lamiophlomis rotata(Labiatae).Their structures were determined on the basis of chemical and spectral analysis(IR,MS, 1HNMR and13CNMR).The two compounds were3-hydroxy-4-methoxy-phenethyl-O-α-L-rhamnopyranosyl(1→3)-O-β-D-apiofuranosyl(1→6)-4-O-feruloyl-β-D-glucopyanoside(1)and3-methoxy-4-hydroxy-phenethyl-o-α-L-rhamnopyranosyl( 1→3)-O-β-D-apiofuranosyl (1→6)-4-O-feruloyl-β-D-glucopyanoside(2).The latter is a new compound and named as lamiophlomioside A.
