A rapid method for the extraction and estimation of morphine in Indian opium is described. Methanolic extract of opium is treated with activated charcoal and the colorless extract obtained contains all of the major opium alkaloids. Morphine content is estimated colorimetrically by using hydrogen peroxide-copper-ammonia. The reaction is specific for morphine, and no other major opium alkaloid responds. The results obtained by the proposed method are in general agreement with those obtained by the nitroso method.
本文描述了一种快速提取和测定印度鸦片中吗啡的方法。鸦片的甲醇提取物用活性炭处理，得到的无色提取物含有所有主要鸦片生物碱。吗啡含量通过过氧化氢-铜-氨比色法测定。该反应对吗啡具有特异性，其他主要鸦片生物碱无反应。该方法得到的结果与亚硝基法得到的结果总体一致。
