ABSTRACT
The phenolic constituents of Wikstroemia chamaedaphne were investigated by various column chromatographic methods including silica gel,Sephadex LH-20,ODS and preparative HPLC,and their chemical structures were identified by physico-chemical properties and spectral analyses. Thirteen phenolic compounds were isolated and elucidated,including five flavonoids luteolin 7-O-β-D-glucopyranoside(1),luteolin 4'-O-β-D-glucopyranoside(2),kaempferol 3-O-β-D-glucopyranoside(3),chrysoeriol 4'-O-β-D-glucopyranoside(4),chrysoeriol(5); and eight lignans(-)-secoisolariciresinol(6),acanthosessilin A(7),(-)-nortrachelogenin(8),(+)-isolariciresinol(9),sesamin(10),syringaresinol(11),(+)-epipinoresinol(12),and [3,3',4,4'-tetrahydro-6,6'-dimethoxy-3,3'-bi-2 H-benzopyran]-4,4'-diol(13). Compounds 1, 3, 5-8, 10, 11 and 13 were obtained from the plants of W. chamaedaphne for the first time,and compounds 1,5,7,10 and 13 were obtained from the Wikstroemia genus for the first time.
