To study the changes of chemical constituents in Pollen Typhae(Puhuang) after processing.
The contents of two flavonoids, typhaneoside(I) and isorhamnetin-3-O-neohesperidoside(II), in Pollen Typhae (Puhuang) and its different processed products were determined by HPLC.
Compared with the crude drug, the contents of I and II decreased by 40.22% and 49.87% respectively in the stir-fried product. I and II were not detected in the carbonized product.
The decrease of contents of I and II after processing shows that the chemical constituents in Pollen Typhae (Puhuang) have changed after processing.
研究蒲黄炮制后化学成分的变化。
采用高效液相色谱法测定蒲黄及其不同炮制品中两种黄酮类成分异鼠李素-3-O-新橙皮糖苷（I）和异鼠李素（II）的含量。
与生品相比，炒制品中I和II的含量分别降低了40.22%和49.87%。炭制品中未检测到I和II。
炮制后I和II含量降低，表明蒲黄炮制后化学成分发生了变化。
