Abstract


In this study, the chemical composition of the essential oil of Premna coriacea leaves was investigated. Extraction by hydrodistillation followed by gas chromatography and mass spectrometry (GC-MS) yielded 27 compounds representing 99.89% of the oil. The major volatile components of the oil were aromadendrene (23.51), caryophyllene (19.27), tetracontane (11.90), 17-pentatriacontene (6.61), 3',8,8'-trimethoxy-3-piperidyl-2,2'- binaphthalene-1,1',4,4'-tetrone (4.68), cis-α-bisabolene (4.65), octadecane, 3-ethyl-5-(2-ethylbutyl)- (4.21), 2-mercaptobenzothiazole (3.17) and tetratetracontane (2.38).

Keywords: Premna coriacea, essential oil, aromadendrene, caryophyllene
