摘要：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.
