Selection Of

Morphine (MO) as an opioid analgesic is used for the treatment of moderate-to-severe pains, particularly cancer-related pains. Pharmacologic studies on MO are complicated due to drugs binding to the protein or metabolization to active metabolites, and even inter-individual variability. This necessitates the selection of a reliable analytical method for monitoring MO and the concentrations of its metabolites in the biological samples for the pharmacokinetic or pharmacodynamic investigations. Therefore, this study was conducted to review all the analytical research carried out on MO and its metabolites in the biological samples during 2007–2019 as an update to the study by Bosch et al. (2007).

Good Agreement

Abstract An objective analytical method for the estimation of bitterness of fresh and fermented olives has been developed. Results of the bitterness estimation by the proposed method were in good agreement with organoleptic tests performed concomitantly. The method is based on the extraction with acetone of a bitter constituent from the olive, adsorption of possible interfering materials on gelatin and alumina, and spectrophotometric determination of the resulting bitter solution.
