英文摘要 |
Despite the fact that chromatographic fingerprint analysis has been used increasingly for the identification of Chinese herbal medicines, there is no recognized procedure for the establishment of characteristic fingerprint chromatogram. In this paper, a chromatographic response function (CRF) was introduced to quantitatively compare chromatograms obtained under different experimental conditions. As a result, the optimum experimental conditions for the establishment of characteristic fingerprint chromatogram could be identified. Moreover, since the proposed function involved data that were directly available from the workstation after each chromatographic analysis, calculation could be automated. In this paper, the function was successfully applied to obtain characteristic fingerprint chromatogram for Chinese herb Langdu.
雖然指紋圖譜分析愈來愈多被應用於中草藥材的鑑定,但如何取得一幅特徵指紋圖譜,至今仍未見文獻中有所報導。我們知道不同的實驗條件,會給出一個對應的色譜圖譜。要分辨那一個圖譜可作為鑑定用的特徵指紋圖譜,就需要一個客觀和合理的指標,用來比較在不同實驗條件下所產生的色譜圖譜。本文介紹一個新的色譜響應函數,去定量比較由不同實驗條件下所產生的指紋圖譜,從而辨別出那一個是特徵指紋圖譜。另外此色譜響應函數所需的數據資料,均可於每次色譜分析後,直接從儀器工作站取得,因此可利用自動化運算。本文成功利用此色譜響應函數,取得中草藥材狼毒的特徵指紋圖譜,且證明這特徵指紋圖譜能用於分辨不同品種的狼毒藥材及其他有關藥材。 |
