Quantification of Morphine, Codeine, and Dihydrocodeine in Carissa carandas Leaves and Fruit Using LC-MS/MS: The Impact of Drying on Alkaloid Concentration
Abstract: This study presents a method for quantifying morphine, codeine, and dihydrocodeine in Carissa carandas (Karonda) leaves and fruit, employing morphine-D3 as an internal standard (1 µg/mL) to ensure accuracy. Samples are prepared at 25 ng/mL and extracted using solvent techniques, with an optional solid-phase extraction step to mitigate matrix effects. Quantification is conducted via LC-MS/MS, providing robust sensitivity. Results show that drying concentrates these alkaloids, particularly morphine in fruit, due …
