摘要

以採逢機取樣方式價購大台北地區中藥材商市售白前、白薇檢體各50件，合計100件，並與芫花葉白前、柳葉白前、直立白薇、徐長卿等四種對照藥材比對，由文獻之比對並以性狀特徵、組織切片、理化及鏡檢鑑定其基原。
經調查市售白前檢體50件中，經確認3件為芫花葉白前，47件為直立白薇；市售白薇檢體50件中，經確認2件為直立白薇，48件為白前。48件白前中有46件為芫花葉白前，2件為柳葉白前。50家中藥商所販賣的兩種藥材皆為芫花葉白前者有3家，皆為直立白薇者有2家，其餘皆使用相反；50家中藥商中未有所販賣之兩種藥材皆為正品者；由此可見中藥之白前與白薇混淆使用頗為嚴重。

The Baiqian (白前) and the Baiwei (白薇) are widely used as herbal medicine in Asian countries. They possess different pharmacological effects in the clinical therapy. The adulteration and misusage of each has been reported in the literature. In this study, we purchased samples of both from fifty sellers of Chinese natural drugs in Taipei area, and identified their origins by morphology, microscopy and thin layer chromatography methods with their authenticated materials.
The results showed that the identification of fifty samples of the Baiqian as the Cynanchum atratum Bunge. (直立白薇) and the Cynanchum glaucescens (Dec.) Hand.-Mazz (芫花葉白前) were forty seven and three, respectively. On the contrary, the identification of fifty samples of the Baiwei as the Cynanchum glaucescens (Dec.) Hand.-Mazz., the Cynanchum stauntoni (Decne.) Schltr.ex Levl. (柳葉白前) and the Cynanchum atratum Bunge. were forty six, two and two, respectively.
Furthermore, none of the sellers of Chinese natural drugs sold the correct origins of the products. Selling samples of both with no difference as the Cynanchum glaucescens and the Cynanchum atratum was found in three and two herbal stores, respectively. Misusage of each was present in the other stores. The adulteration and misusage between the Baiqian and the Baiwei in marketing were found to be very serious in this study.
