Chemical Characterization, Antioxidant Activity and GC-MS Analysis of the Extracted Oil from Seeds of Persea americana Mill. (Avocado) Pa Pa San Thida Kyaw From ancient times plants have provided a source of inspiration for novel drug compounds, as plant derived medicines have made large contribution to human health and well being. There is a long tradition of using the pits for various medicinal purposes. Medicinal plants have been of age long remedies for human diseases because they contain components of therapeutic value. In this research work, Avocado seed was selected for chemical analysis. Avocado (Htaw-Bat- Thee) was collected from Pyin-Oo-Lwin Township, Mandalay Region. Firstly, phytochemical screening for the Avocado seed was performed. According to phytochemical screening, alkaloid, glycoside, saponin, phenolic compound, polyphenol, reducing sugar, terpene, lipophenol and tannin compound were found to be present in the Avocado seed. The oil extracted from Avocado seed was done with petroleum ether by using Soxhlet extraction method. The physicochemical parameters, such as specific gravity, viscosity, acid value, saponification value, iodine value and unsaponifiable matter were determined by conventional method. Then, elemental analysis of Avocado seed was performed by using Energy Dispersive X-ray Fluorescence (EDXRF) method. Moreover, the fatty acid composition of Avocado seed oil was analyzed by Gas Chromatography Mass Spectrometry (GC-MS) method. Moreover, antioxidant activities of Avocado seed evaluated on the basis of their scavenging activity of the stable 1, 1-diphenyl 2-picrylhydrazyl (DPPH) free radical. IC50 value was 180.06 g/mL compare to that of ascorbic acid which was 0.65 g/mL. 2019 http://hdl.handle.net/20.500.12678/0000000438 https://meral.edu.mm/records/438
