Abstract:
To study the chemical constituents of Cirsium setosum (Willd.) MB., 70% ethanol extract of the aerial parts was subjected to column chromatography. One new phenylpropanoid glycoside, sinapyl alcohol 9-O-(E)-p-coumaroyl-4-O-beta-D-glucopyanoside (1) was isolated, along with three known compounds: lycoperodine-1 (2), apigenin-7-O-(6"-(E)-p-coumaroyl)-beta-D-galactopyranoside (3) and quercetin (4). The structures were elucidated on the basis of spectral and chemical evidence. Compound 2 was obtained from Cirsium genus for the first time, compounds 3 and 4 were obtained from this plant for the first time.
