Three new di-O-glycosyl-C-glucosyl flavones from the leaves of Caesalpinia ferrea Mart

Z Naturforsch C J Biosci. 2014 Sep-Oct;69(9-10):357-62. doi: 10.5560/znc.2014-0113.

Abstract

Three hitherto unknown di-O-xylosyl-C-glycosyl flavones were isolated from the leaves of Caesalpinia ferrea. The structures of all isolated compounds were elucidated by conventional methods and spectroscopic analysis, including 1D and 2D NMR, as well as by HRESIMS.
