Abstract: Five flavonoid glycosides were isolated from the alcoholic extract of the pollen of Typha angustifolia L. (Typhaceae). Two of them are triglycosides including a new compound, and the other three are diglycosides. On the basis of spectroscopic (UV, IR, MS, ¹HNMR and ¹³CNMR) analysis and identification of the acidic hydrolytic products the structure of the new compound was elucidated as isorhamnetin-3-o- (2^G-α-L-rhamnopyranosyl) -α-L-rhamnopyranosyl- (1→6)-β-D-glncopyranoside and named typhaneoside(Ⅰ). The four known compounds were identified as kaempferol-3-O-(2^G-α-L-rhamnosyl) rutinoside (Ⅱ), isorhamnetin-3-O-neohesperidoside(Ⅲ), kaempferol-3-O-rhamnosylglucoside(Ⅳ) and quercetin-3-O-neohesperidoside(Ⅴ), respectively. Compound Ⅱ was found in this genus for the first time.
