水法提取黄连素已在部队推广应用,但黄連素的含量测定迄今尚无簡便的方法,一般多采用重量法,操作費时,又不准确,且需恒温干燥設备。我們对黄連素含量測定法作了研究后,得出一种簡便可行的容量分析法——碘酸鉀法,現簡单介紹如下,供部队药工人員参考采用。准确称取一定量的黄連素样品(0.2—0.3克即可),在150毫升燒杯中,加沸蒸餾水約40毫升,使溶解,泠至室温移入100毫升容量瓶中,自滴定管准 Water extraction of berberine has been in the army to promote the application, but the determination of berberine so far there is no easy way, the general use of weight method, the operation time-consuming, not accurate, and the need for constant temperature drying equipment. After we studied the determination of berberine content, obtained a simple and feasible capacity analysis method - potassium iodate method, is now briefly described below, for the military and pharmaceutical workers reference. Accurately weigh a certain amount of berberine sample (0.2-0.3 g can be), in a 150 ml beaker, add boiling distilled water about 40 ml, the dissolved, cooled to room temperature into 100 ml volumetric flask, burette
