In this work, we reported the application and validation of an improved high-performance liquid chromatography method coupled with a fluorimetric detector (HPLC-FL) to screen the activity of two heterocyclic derivatives reported as serine palmitoyl transferase (SPT) inhibitors. The analytical conditions were optimized in terms of the derivatization procedure, chromatographic condition, extracti...
apigenin is best known as an irreversible inhibitor of monoamine oxidase (mao), an intracellular enzyme associated with the outer membrane of mitochondria. the purpose of this study is to establish a reliable and quick method for the assignment of apigenin in cosmos bipinnatus, apium graveolens and petroselinum crispum by high performance liquid chromatography with ultraviolet detection (hplc-u...
