【摘要】 自香蒲科（Typhaceae）植物狭叶香蒲（Typha augustifolia L.）的干燥花粉中分离到五个黄酮醇甙,包括两个黄酮醇-3-三糖甙（Ⅰ,Ⅱ）和三个黄酮醇-3-双糖甙（Ⅲ,Ⅳ,Ⅴ）。其中,化合物Ⅰ是一个新的黄酮醇甙,为本植物的主要成分,经光谱分析(UV,IR.MS;¹HNMR和¹³CNMR)和水解试验确定为异鼠李素-3-0-（2^G-α-L-鼠李糖基）-α-L-鼠李糖（1→6）-β-D-葡萄糖甙,命名为香蒲新甙（typhaneoside,Ⅰ）。其它四种为已知成分。Ⅱ从本属植物中首次发现。更多还原

【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.更多还原
