Chemical constituents of Caragana bungei shoots

ABSTRACT

The phytochemical study of flowering shoots of Caragana bungei Ledeb., Fabaceae, collected in Tuva Republic (Russian Federation) resulted in the isolation of sixteen compounds identified as β-sitosterol, β-sitosterol-3-O-glucoside, umbelliferone, kaempferol, quercetin, isorhamnetin-3-O-glucoside, isoquercitrin, rutin, narcissin, nicotiflorin, caffeic acid, 3-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid, gallic acid and sucrose. The structures of the compounds were established by spectral analyses. This is the first phytochemical investigation of C. bungei. The nicotiflorin, phenylpropanoids and gallic acid were isolated from the Caragana genus for the first time.
