OBERST YR 1942 UL http://jpet.aspetjournals.org/content/74/1/37.abstract AB A modified method for the micro-determination of morphine in quantities from 0.03 to 0.2 mgm. by the morphine-molybdate-vanadate procedure has been described. Morphine analyses were made on urine, feces, saliva, gastric contents, perspiration, bile, and blood from morphine addicts, as well as liver obtained at autopsy on two patients who were addicted at the time of death. Feces, liver, and perspiration contained free morphine; bile contained only bound morphine; urine and gastric contents contained both free and bound morphine; no morphine was found in saliva or blood.
