Determination of promethazine hydrochloride in Shangfeng zhike granules by colorimetry-dual wavelength spectrophotometry

, : Determination of promethazine hydrochloride in Shangfeng zhike granules by colorimetry-dual wavelength spectrophotometry. Zhongguo Yiyao Gongye Zazhi 25(12): 549-551

Promethazine hydrochloride in SHANGFENG ZHIKE granules, was determined by colorimetry-dual wavelength spectrophotometry without. preliminary separation. The average recovery was 100.1% (RSD=0.88%). The method was simple, rapid and accurate.
