    • A process for testing a composition as containing an artemisinin derivative is provided that includes contacting the composition with a reagent made up of a hydrogen bonding polar organic solvent and an acid having a pK value of less than 3.8 at 25° Celsius and capable of acid catalyzing a decomposition reaction of the artemisinin derivative so as to provide a reaction mixture. The reaction mixture is allowed sufficient time at a reaction temperature for the artemisinin derivative to decompose to yield a colored decomposition product discerned by a normal unaided human eye. A kit for testing a composition for an artemisinin derivative according to the process is provided together with instructions for contacting the solvent and the acid with the composition to decompose the artemisinin derivative to yield the colored decomposition.
    • 提供了测试含有青蒿素衍生物的组合物的方法,其包括使组合物与氢键极性有机溶剂和pK值小于3.8的酸在25℃下接触并能够酸催化 青蒿素衍生物的分解反应以提供反应混合物。 反应混合物在反应温度下允许足够的时间使青蒿素衍生物分解,从而产生由正常肉眼辨别出的着色分解产物。 提供根据该方法测试青蒿素衍生物的组合物的试剂盒以及用于使溶剂和酸与组合物接触的说明书,以分解青蒿素衍生物以产生着色分解。
