Acylated flavonol glycoside from Psidium gauijava L. seeds.
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.
