title: Flavonol sinapoyl glycosides from leaves of Thevetia peruviana.
abstract: From the leaves of Thevetia peruviana four new flavonol glycosides, kaempferol 3-glucosyl(1 --> 4) [6"'-sinapoylglucosyl] (1 --> 2) galactoside and 3-[2""-sinapoylglucosyl](1 --> 4)[6"'-sinapoylglucosyl](1 --> 2)galactoside and kaempferol and quercetin 3-[6"'-sinapoylglucosyl](1 --> 2)galactoside were isolated, together with the known compounds, kaempferol and quercetin 3-glucosyl(1 --> 2)galactoside. The glycosides were characterized from FAB mass, 1H and 13C NMR and UV spectral data.
