Studies on Adulteration and Misusage of Baitouweng in Marketing

白頭翁藥材係毛莨科（Ranunculaceae）植物白頭翁Pulsatilla chinensis(Bunge)Regel之乾燥根。於大台北地區中藥店採逢機取樣方式價購了25件白頭翁檢體，此25件白頭翁檢體中，經性狀特徵及組織切片鏡檢，並與對照藥材及文獻比對，確認20件為薔薇科（Rosaceae）植物委陵菜Potentilla chinensis Seringe，5件為石竹科（Caryophyllaceae）植物白鼓釘Polycarpaea corymbosa Lamarck，而未發現正品。另由國內中藥廠提供白頭翁藥材8件，經鑑別確認白頭翁1件，委陵菜6件，白鼓釘1件。由此可見白頭翁藥材使用情形頗為混亂。

The origin of Baitouweng (Pulsatillae Radix) is the root of Pulsatilla chinensis (Bunge) Regel (Ranunculaceae). In this study, we purchased twenty-five samples of Baitouweng from twenty-five Chinese herbal stores in Taipei area, and eight samples received from pharmaceutical manufactories. Samples were compared with authentic materials to identify their characteristics by morphology and microscopy.The results shown that the twenty-five samples of the Baitouweng were analysed and conformed to the Potentilla chinensis Seringe (委陵菜) and the Polycarpaea corymbosa Lamarck (白鼓釘). The former were of twenty one samples and the latter were of five, respectively. None of the true Baitouweng was purchased from the Chinese herbal stores this time.Among the eight samples obtained from pharmaceutical manufactories, one of them was Pulsatilla chinensis (Bunge) Regel, one of them was Polycarpaea corymbosa Lamarck and six of them were Potentilla chinensis Seringe.According to the results, the adulteration and misusage of Baitouweng in the market are serious.
