Abstract
Phytochemical investigation of the ethyl acetate soluble fraction of the methanol soluble extract of the roots of Daphne oleoides resulted in isolation and identification of two new isomeric biisoflavonoids characterized as 8,8"-bi-6-hydroxyorobol (1) and 8,8"-bi-6, 2'-dihydroxygenistein (2). The structures of these compounds were established by analysis of their 1D and 2D NMR and HRMS data.
