Abstract
A novel acylated quercetin tetraglycoside, namely quercetin 3-O-(2G-p-coumaroyl-3G-O-β-l-arabinosyl-3R-O-β-d-glucosylrutinoside) was isolated from oolong tea (Camelia sinensis) extracts. Structural analysis of this compound was achieved by NMR, TOF-MS and high-resolution FAB-MS. Triglycosyl flavonols have previously been reported from tea leaves and tea seeds however this is the first report of an aromatic acylated and tetraglycosyl flavonol.
