title: Flavone C-glycosides from Trichuriella monsoniae (L.f.) Bennet.
abstract: In the first phytochemical investigation of Trichuriella monsoniae, three known flavonoidal C-glycosides, isoswertisin 1, 2″-O-β-d-galactosyl isoswertisin 2 and 2″-O-β-d-xylosyl isoswertisin 3 were isolated from the methanolic extract of the whole plant. Their structures were elucidated by extensive NMR spectroscopic studies including 2D NMR and HRMS, and the structure of 2 was supported by single crystal X-ray data studies. Further, NMR assignments for 3 are being reported for the first time.
