Abstract: Steeping of poppies in 7.5% Na2CO3 or 10% NH4OH and extn. for 4 hrs. were found satisfactory for detn. The detn. of alkaloids is divided into 2 parts: (1) the detn. of morphine and (2) the detn. of other opium alkaloids. A titration method for morphine was described and compared with a gravimetric method by Mannich (C.A. 38, 4754.2). The titration method gives 0.04% higher results because it includes the narcotine present in poppies. The other opium alkaloids were detd. by a gravimetric method which may show higher results.
