title: Acylated flavonol glycoside from Psidium gauijava L. seeds.
abstract: Ten phenolic and flavonoid compounds including one new acylated flavonol glycoside were isolated from Psidium gauijava seeds. The structures of the new compound quercetin-3-O-beta-D-(2"-O-galloyl glucoside)-4'-O-vinylpropionate and of the known compounds were elucidated by different chemical and physical methods, 1H- and 13C NMR spectral analysis.
