近年來政府積極推行中藥GMP政策，以提高中藥及中藥製劑水準。然而有些中藥材之基原頗為複雜，商品名稱及來源亦很混亂，且常有代用品或膺偽品充斥其間，因此有必要對基原較複雜之藥材加以釐清。因此本年擬繼續進行臺灣市售易混用、誤用中藥品種之檢討，以板藍根、大青葉及青黛等藥材為對象，進行(1)各種市售板藍根、大青葉及青黛市場品之收集(2)文獻調查：本草考察、藥用植物學考察、化學成分考察、藥理及臨床應用文獻考察；(3)臺灣本產板藍根、大青葉及青黛植物之收集；(4)顯微鑑別；(5)化學鑑別：以TLC及HPLC與指標成分作定性定量比對；(6)市售含板藍根、大青葉及青黛中藥方劑製劑中，板藍根、大青葉及青黛藥材選用調查；(7)對各種市售板藍根、大青葉及青黛進行藥理活性評估比較；(8)利用現有? B藥理、臨床等文獻資料及本實驗所作藥理活性評估結果，依各成方方劑之臨床主治，對該方中所應使用之板藍根、大青葉及青黛種類加以建議統一；以期對此三類藥材作有系統之分析，提供中醫界、中藥界及各中藥廠參考，做到「藥知病用，醫知藥情」，以達到全面提昇中藥品質之理想。

Studies on the Commonly Misuesd, Adulterated Chinese Crude Drug Species in Taiwan(Ⅱ)

In recent years, the Chinese Government in Taiwan started GMP policies to elevate the quality standard of the Chinese crude drug preparations. However, the name and origin of some crude drugs are confusing. Substitution and adulteration are very common. Therefore it is essential to clarify the origins of those confused drugs.

In the current year, Ban-Lan-Gen(Isatidis Radix), Da-Ching-Yeh(Isatidis Folium), Ching-Dai(Indigo Naturalis) and the preparations containing those three herbs will be studied. Each drug will be investigated in the following aspects:


1.Various commercially available samples of the three drugs will be collected. 
2.Literature search on Pentsaology, medicinal plants, chemical components, pharmacological activities and clinical efficacy of the three herbs will be carried out. 
3.Native species of Ban-Lan-Gen and Ta-Ching-Yeh will be collected and compared. 
4.Microscopic examinatin of the three species will be performed for identification. 
5.Chemical
