肉蓯蓉基原為荒漠肉蓯蓉Cistanche deserticola Y. C. Ma的乾燥帶鱗葉的肉質莖,為補腎壯陽常用中藥,使用歷史悠久,《神農本草經》列為上品。肉蓯蓉為產於沙漠的寄生植物,藥源一直非常緊缺,故歷代時有代用品、偽品出現。為了解市售肉蓯蓉之基原,本計劃除收集正品荒漠肉蓯蓉對照藥材外,另收集鹽生肉蓯蓉Cistanche salsa (C. A. Mey)Benth. et Hook. F.、管花肉蓯蓉Cistanche tubulosa (Schrenk.) R. Wight 與草蓯蓉 Boschniakia rossia (Cham. et Schitdl) Fedtsch. et Flerov等對照藥材一併比較,利用性狀特徵、組織鏡檢及薄層層析法,建立肉蓯蓉藥材之鑑別方法。 市售50件肉蓯蓉檢體採逢機取樣方式於台北、台中和高雄地區之中藥店價購,所購之檢體與對照藥材比對,並參照文獻之記載進行基原鑑別。結果顯示50件均為正品荒漠肉蓯蓉,並無偽品使用情形。
Cistanchis Herba, the dried entire plant of Cistanche deserticola Y. C. Ma of the Orobanchaceae Family, was recorded in Shen Nung Pen Tsao Ching as a superior herb. Cistanchis Herba is a parasitic plant, and the yield was insufficient for demand. Therefore, there were a number of alternatives and adulterants stated in ancient books. In order to clarify the botanical origins of Cistanchis Herba in Taiwan market, fifty samples of Cistanchis Herba were purchased from Chinese herbal stores in Taipei, Taichung and Kaohsiung. In addition, Cistanche deserticola, Cistanche salsa, Cistanche tubelosa and Boschniakia rossia were collected as authentic materials. Commercial samples were compared to the authentic materials and identified with their characteristics by morphology, microscopy and thin layer chromatographic analysis. The result showed that all commercial samples were Cistanche deserticola. Furthermore, this study presented approaches for the identification of Cistanchis Herba.
