Studies on the Constituents of Sophora Species. II. Constituents of Sophora subprostrata CHUN et T. CHEN. (2). Isolation and Structure of New Flavonoids, Sophoradochromene and Sophoranochromene

Abstract

From the root of Sophora subprostrata CHUN et T. CHEN two new flavonoids, named sophoradin and sophoranone, have been isolated, whose structures have been established to be I and IX, respectively, by the spectral properties of them and their derivatives and by chemical data.
