中文摘要 | 中草藥品質評估試驗中,用於檢驗分析比對之中藥成分對照標準品,因缺乏公認之標準,其品質參差不齊。本計畫依前所建立之「中藥成分對照標準品實驗室間共同比對試驗機制」模式,除本局外,邀請其他6個實驗室共同參與試驗,進行葛根素(Puerarin)檢品原料之各項理化學共同試驗。彙整7個實驗室之試驗結果,UV光譜最大吸收波長λmax = 249.9,305.7 nm,比吸光度E1 % = 736.8,248.8。IR光譜吸收位置在3366,3234,1633,1515及1059 cm-1具有Puerarin特有之吸收。高效液相層析檢測結果,7個參與實驗室分別檢出1-6個微量不純物,其不純物之含量均≦0.50%,總不純物之含量亦均≦0.84%。以上數據顯示,本批葛根素原料,其品質應可做為葛根素對照標準品。本計畫除供應具有公認品質基礎之中藥成分對照標準品外,亦建立未來供應中藥成分對照標準品之品管模式,使中藥成分對照標準品品質邁向國際水準。 |
英文摘要 | The raw material of Puerarin was examined prior to the preparation of the “Puerarin Reference Standard”. The physico-chemical properities of the candidate material were evaluated by a collaborative study among seven laboratories. Analytical data obtained were summarized as follows: the UV maximum absorption wavelengths and the corresponding specific absorbencies (E1%) were 249.9, 305.7 nm, and 736.8, 248.8, respectively. IR Spectra showed that IR absorption at 3366, 3234, 1633, 1515 and 1059 cm-1. HPLC analysis revealed 1-6 impurities which individual amount was≤0.50% and the total amount from any single laboratory was ≤ 0.84%. Based on the above results, the candidate material met the requirement of authorization as thePuerarin Reference Standard. |
