Abstract
Chemical constituents and biological activities of the Mitrella kentii leaf oil were investigated in this study. Gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used to determine the chemical constituents of the oil. The oil was evaluated for its ability to inhibit prostaglandin E 2 (PGE 2 ) and thromboxane B 2 (TXB 2 ) productions in human whole blood using a radioimmunoassay technique. Its inhibitory effect on platelet-activating factor (PAF) receptor binding with rabbit platelets using 3 H-PAF as a ligand and its free radical scavenging effect on DPPH were also investigated. Caryophyllene oxide (33.8%), E , Z -farnesol (6.9%), benzyl benzoate (6.5%) and viridiflorol (6.5%) were among the major components of the oil. Even though weak inhibitory activities were observed in both PGE 2 and TXB 2 assays, significant results were obtained in both PAF receptor binding inhibition and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging effect with IC 50 value of 6.6 µg/mL and 155.6 µg/mL respectively. These promising activities warrant the development of the oil as an anti-inflammatory agent. DOI : http://dx.doi.org/10.17576/JSKM-2021-1901-17
