Abstract : Universiti Pendidikan Sultan Idris
This study aimed to analyze the essential oils composition, phytochemistry, anatomical and antioxidant activity of the genus Vitex (V. negundo and V. trifolia) and Plectranthus (P. amboinicus and P. monostachyus) from Lamiaceae family. The essential oils were obtained via hydrodistillation technique and their chemical compositions were determined by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The phytochemicals were obtained using chromatography techniques and their structures were confirmed by spectroscopic data and comparison with literatures. The anatomical study have been investigated on the lamina, midrib and petiole of the leaves part. The antioxidant activity of the essential oils was investigated using DPPH free radical scavenging assay. The study showed a total of 14 and 18 components were identified from the leaf oils of V. negundo (92.8%) and V. trifolia (91.5%), respectively. The results revealed that the essential oils are made up principally of δ-elemene (43.1%), spathulenol (9.8%), δ-selinene (7.8%) for V. negundo, while viridiflorol (42.3%), β-caryophyllene (21.7%), and β-elemene for V. trifolia. In the case of Plectranthus essential oils, 20 components was found from P. amboinicus (91.1%) and 37 components were identified from P. monostachyus (98.8%) oils. The major components of P. amboinicus oil were carvacrol (54.4%), β-caryophyllene (8.9%), and α-cisbergamotene (7.7%), whereas P. monostachyus oil gave β-caryophyllene (26.2%), germacrene D (12.5%), δ-cadinene (9.2%), and germcarene B (8.8%). In addition, viridiflorol and carvacrol have been successfully isolated from the crude oils, whereas vanillic acid, vanillin, β-sitosterol and β-sitostenone were identified from the crude extracts. The essential oil of P. amboinicus displayed strong antioxidant activity with IC50 value 32.5 μg/mL. Meanwhile, the oil gland has been found in lamina, midrib and petiole of all essential oils. As conclusion, the composition of the essential oils from four species of Lamiaceae family have shown various chemical components and proved via anatomical study. The implication of this study demonstrates the importance of the characterization of Lamiaceae taxa in elucidating phylogenetic relationships as well as the potential of Plectranthus essential oils as a source of natural antioxidants.
