本檢驗法旨在鑑定中藥降壓利尿類製劑可能摻加之西藥成分。將檢品經抽取處理後,用薄層層析法與標準品及中藥對照品作對照試驗,若呈「陽性」反應者,即挖取層析斑點再抽取、精製並測繪UV吸收光譜等比對鑑定之。此方法迅速、精確,可供作不法藥物之檢驗基準。
The purpose of this study is to detect and identify medicine ingredients which have been found in some antihypertensive-diuretic Chinese Herb preparations. The sample is extracted with a suitable solvent, at the same time the Reference preparation is also extracted with the same solvent. Using TLC to compare the chromatograms of the sample extract, Reference preparation extract and adulterated reference standard. If the result is positive, then re-extraction and purification of the spots obtained from TLC plate, and use the UV spectrophotometry to conform it. The above method is quick and precious, can be carried out satisfactorily to detect illegal Chinese Herb preparations.
