Studies on the Constituents of the Leaves of Cassia torosa CAV. I. : The Structures of Two New C-Glycosylflavones

Abstract

Two novel C-2, 6-dideoxyglycosylflavones, torosaflavones A (1) and B (2), were isolated from the leaves of Cassia torosa CAV. The structures of the new compounds 1 and 2 were established as apigenin 6-C-β-D-olioside and diosmetin 6-C-β-D-olioside, respectively, on the basis of spectral and X-ray analysis.
