title: Dihydrolicoisoflavone, a new isoflavanone from Swartzia polyphylla.
abstract: Fractionation of an ethanolic extract of Swartzia polyphylla, guided in part by an assay for inhibition of protein kinase C, led to the isolation of the known flavonoids biochanin A, dihydrobiochanin A, ferreirin, dalbergioidin, and naringenin, and one new prenylated isoflavonone, dihydrolicoisoflavone [1].
