- W2007990062 abstract "Pharmaceutical preparations of heroin and cocaine more than seventy years old were analyzed using RP-HPLC. The composition of mobile phase was optimized. The components were identified by MS2 or MS3, and the APPI fragmentation mechanisms of compounds found were proposed. The sample of heroin hydrochloride injection solution consists of 96.1% morphine and 3.9% of codeine. The sample of cocaine hydrochloride injection solution consists of 26.9% cocaine, 31.5% benzoylecgonine, 17.4% ecgonine, and 24.2% ecgonine methyl ester." @default.
