Flavonoids from flowers of Malva crispa L. (Malvaceae).
The following flavonoids were isolated and identified from the flowers of Malva crispa L.: kaempferol 3-O-beta-glucopyranoside, 3-O-(6"-tran-p-coumaroyl)-beta-D-glucopyranoside, 7-O-beta-D-glucopyranoside, 3-O-alpha-L-rhamnopyranosyl (1-->6)-beta-D-glucopyranoside and 3,7-O-diglucoside as well as quercetin 3-O-beta-D-glucopyranoside, 3-O-alpha-L-rhamnopyranosyl (1-->6) -beta-D-glucopyranoside and apigenin 7-O-beta-D-glucopyranoside. Their structures were established by chemical analysis, UV, 1H and 13C NMR spectrometry.
