Four new compounds isolated from the aerial part of belamcanda chinensis (L.) and their effect on vascular smooth muscle cell (VSMC) proliferation

Abstract

Bio-guided fractionation of the 70% ethanol extract of Belamcanda chinensis (L.) DC. revealed four new compounds, including 6″-O-acetylembinin (5), 3″-O-acetylembinin (6), irigenin 3′-O-β-glucopyranoside (8), and 2′-acetyl-1,3-O-diferuloylsucrose (9), along with five known compounds (1–4, 7). Their chemical structures were determined using extensive NMR data, mass spectroscopy, and comparison with published literature. Among the isolates, compounds 1 and 4–7 achieved good regulation of the growth and proliferation of vascular smooth muscle cells.
