This paper deals with the determination of flavonoids and quality evaluation of Chinese Typha. Four species, viz. Typha angustata, T. angustifolia, T. davidiana and T. latifolia and eight commercial samples of Chinese traditional drug "Puhuang" were collected. Five flavonoids in pollen, filaments, female flowers and leaves were determined by HPLC using mu-Bondapak C18 column, water--isopropanol--tetrahydrofuran = 83.5:14:2.5, as mokile phase and detected at 287 nm). The qualities of different Typha species and commercial "Puhuang" samples have been compared, and the criteria for their quality control were also discussed.
本文研究了香蒲属植物中黄酮类化合物的测定及质量评价。采集了四种香蒲属植物，即狭叶香蒲、水烛、小香蒲和宽叶香蒲，以及八个中药“蒲黄”的商业样品。采用μ-Bondapak C18柱，以水-异丙醇-四氢呋喃=83.5:14:2.5为流动相，在287nm波长下，用高效液相色谱法测定了花粉、花丝、雌花和叶片中的五种黄酮类化合物。比较了不同香蒲属植物和商业“蒲黄”样品的质量，并讨论了其质量控制标准。
