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,共邀請5個實驗室參與,進行甘草酸(Glycyrrhizinic acid)對照標準品原料之各項理化學共同試驗。彙整6個實驗室之試驗結果,UV吸收光譜λ max =251.1nm,比吸光度E1 %1cm (EtOH) = 140.8。IR吸收光譜在1719,1654,1216及1170 cm-1具有Glycyrrhizinic acid特有之吸收。另薄層層析檢測結果,僅1家實驗室,除主斑點外,亦檢測出2個不明顯之斑點。至於高效液相層析檢測結果,6個參與實驗室分別檢出1~7個微量不純物,其不純物之含量均 ≦ 0.22%,總不純物含量亦均 ≦ 0.50%。另實驗材料之融點測定結果為213 ~ 215℃。以上數據顯示,本甘草酸對照標準品原料,其品質應可做為甘草酸對照標準品。本計畫除完成我國第一個具有公認品質基礎之中藥成分對照標準品,供應所需外,亦建立未來製造中藥成分對照標準品之品管模式,使我國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 glycyrrhizinic acid was examined prior to the preparation of the “Glycyrrhizinic Acid Reference Standard”. The candidate material was evaluated physico-chemically by a collaborative study in which six laboratories participated. Analytical data obtained were as follows: The UV absorption maximum showed at 251.1 nm and the specific absorbance at the maxima was 140.8. IR Spectrum showed specific
absorption at 1719, 1654, 1216 and 1170 cm-1. Only one laboratory detected trace amount of two spots by thinlayer chromatography. HPLC analysis showed 1~7 impurities where individual amount were estimated to be equal to or less than 0.22% and the total amount from a single laboratory was equal to or less than 0.50%.
Base on the above results, the candidate material was authorized as the Glycyrrhizinic Acid Reference Standard.
