Abstract
Magnolosides B and C. new phynylpropanoid glycosides have been isolated from the MeOH extract of (Magnolia)___- (obovata)___- Thunb. on the basis of spectroscopic data and chemical evidence. their structures have been established respectively as 3, 4-dihydroxy-β-phenyl-ethyl-o-α-L-rhamnopyranosyl-(1→2)-o-β-D-glucopyranosyl-(1→6)-3-O-caffeoyl-β-D-allopyranoside and 3, 4-dihydroxy-β-phynyl-ethyl-O-α-L-rhamnopyranosyl-(1→2)-O-[O-β-D-glucopyranosyl-(1->4)-β-D-glucopyranosyl-(1→6)]-3-O-cayyeoyl-β-D-allopyranoside.
