2kg of pollen extracted with EtOH(98%), concentrated, and fractionated with a series of hexane, CH$_2$Cl$_2$ EtOAc and $H_2O$ on a separately funnel. Each fraction was freeze dried to give dark-brown powder and EtOAc soluble portion of the powder was chromatographed on a Sephadex LH-20 column using a series of aqueous methanol as eluents. Spectrometric analysis such as NMR and FAB-MS including TLC were performed to characterize the structures of isolated compounds. Pollen contained a small amount of flavonol derivatives such as quercetin-3-O-$\beta$-D-glucopyranoside and kaempferol-3-O-$\beta$-D-rutinoside in addition to a small amount of flavanonol compound such as aromadendrin-5-methyl ether and acid compound such as.
