Objective  To investigate the chemical constituents of the methanolic extract from the stamens of Capparis bodinieri Lévl..

Methods  The dried stamens were extracted with methanol and concentrated to obtain an extract. The extract was then isolated and purified using silica gel column chromatography, ODS column chromatography, Sephadex LH-20 column chromatography, and semi-preparative HPLC. The structures of the compounds were elucidated by spectroscopic methods such as MS and NMR.

Results  Twenty compounds were isolated from the stamens of Capparis bodinieri Lévl, and identified as kaempferol, tamarixetin, kaempferol 3-O-α-D-arabinopyranoside, kaempferol 3-O-β-D-galactopyranoside, guaijaverin, isorhamnetin-3-O-α-L-arabinopyranoside, hyperoside, isoquercitrin, kaempferol-3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside, kaempferol-3-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranoside, quercetin 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside, quercetin 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside, kaempferol 3-O-(2,6-di-α-L-rhamnopyranosyl)-β-D-glucopyranoside, isorhamnetin-3-O-(2″,6″-di-O-α-L-rhamnopyranosyl)-β-D-glucopyranoside, quercetin 3-O-(2″,6″-di-O-α-L-rhamnopyranosyl)-β-D-galactopyranoside, isorhamnetin-3-O-α-L-rhamnopyranosyl-(1→6)-[α-L-rhamnopyranosyl-(1→2)]-β-D-galactoside, benzoic acid, trans-cinnamic acid, stachydrine, and methyl pheophorbide A.

Conclusion  All compounds are reported for the first time from Capparis bodinieri Lévl.
