近來,因中医界發現紫草可用於预防麻疹,各地並試制紫草制剂以供臨床使用,故有關紫草化学研究的文献極被注意,但外國舊雜誌或文献流傳不廣,故特摘譯出紫草素化学性質及其提取法的資料,以供医藥界同人研究参考,制剂工作同人可根据此資料設計紫草素的提煉制剂以及含量测定方法。 Recently, due to the discovery by Chinese medicine practitioners that comfrey can be used to prevent measles, lithospermum preparations have been trial-produced for clinical use. Therefore, the literature on lithosperm chemical research is extremely noted, but foreign old magazines or documents have not been widely circulated. The chemical properties of shikonin and its extraction method are used for research and reference in the pharmaceutical industry. Formulate colleagues can design shikonin extract preparation and content determination methods based on this data.
