Abstract: Twelve compounds were isolated from the Polygala sibirica L.var. megalopha Fr. On the basis of the physico-chemical properties and spectral data, they were identified as syringaldehyde(1), 4-hydroxy-3, 5-dimethoxyacetophenone(2), evofolin-A(3), salicylic acid(4), trans-sinapic acid methyl ester(5), 3,4,5-trimethoxycinnamic acid methyl ester(6), 3,4,5-trimethoxycinnamic acid(7), 5-hydroxy-4',6,7-trimethoxy-flavone(8), sinapylalcohol-4-O-β-D-apiofuranosyl-(1→2)-β-D-glucopyranoside(9),(±)-syringaresinol(10),(+)-medioresinol(11),(±)-pinoresinol(12). All compounds except 4 were isolated from P.sibirica L. for the first time.
