本文介绍了原料药物或各种制荊中测定羟基保泰松(Ⅰ)的一种简易方法。Ⅰ在冰醋酸和盐酸中加热,其水解产物可与香草醛或对-二甲氨基苯甲醛(PDAB)作用呈色,于424毫微米或406毫微米处分别测定其最大吸收。标准曲线的制备:精密吸取若干份标准溶液(100毫克/100毫升冰醋酸),从0.5毫升到2.5毫升配成色阶,分别移入10毫升容 This article describes a simple method for the determination of hydroxy phenylbutazone (I) in raw materials or in various preparations. I was heated in glacial acetic acid and hydrochloric acid. The hydrolyzate was colored with vanillin or p-dimethylaminobenzaldehyde (PDAB) and its maximum absorption was measured at 424 nm or 406 nm. Preparation of standard curve: Precision drawing several standard solutions (100 mg / 100 ml of glacial acetic acid), from 0.5 ml to 2.5 ml dubbed the color level, respectively, into 10 ml volume
