Abstract
A new prenylflavanone dimer named bis-sigmodiol was isolated from Erythrina sigmoidea, along with six known constituents isobavachin, lupiwighteone, orientanol A, ergosta-4, 6, 8 (14), 22-tetraen-3-one, lupenyl acetate, and p-hydroxybenzoic acid. These known constituents have not been reported so far from E. sigmoidea. Their structures were elucidated by spectroscopic methods.
