1 | 2021 thesis | Investigation of essential oils, Phytochemistry and anatomical of Vitex negundo, Vitex trifolia, Plectranthus amboinicus and Plectranthus monostachyus (LAMIACEAE) Fakhira Liyana Mohd Zaki 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..... 604 hits |
