Abstract
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-UV). A rapid and sensitive high performance liquid chromatographic (HPLC) method has been developed for determination of Apigenin in human apigenin. Mobile phase was composed water-acetonitrile (55:45 v/v) with a flow rate of 1 ml/min. The eluted peaks were detected by a UV detector was set at wavelength of 340 nm. The method was validated in the range of Apigenin concentrations from 0.01 to 500 µg/ml. The limits of detection (LOD) and quantitation (LOQ) of the method were 0.005 and 0.01 µg/ml, respectively. The average recovery was 97.28 percent throughout the linear concentration range. The average within-run and between-run accuracy values of 99.32 and 96.79 respectively. The method is quick, simple, sensitive and precise for the screen, assignment, and evaluation of Apigenin in plants by HPLC.
