SECTION I: MOLECULAR GENETIC ENGINEERING AND BIOCHEMICAL TECHNOLOGY 123major compounds included cis-sabinene hydrate acetate, %u03b1-Pinene, trans-Isosafrole, and %u03b3-Terpinene, with relative abundances of 3.38%, 6.44%, 6.45%, and 11.04%, respectively (Table 3). These findings suggest that 1,8-Cineole may be a primary contributor to the bioactivity observed in this essential oil. Previous research by [14] has shown that essential oils with high 1,8-Cineole content exhibited DPPH free radical scavenging activity, with an EC50 of 63.58 %u00b5g/mL. In contrast, compounds such as %u03b3-Terpinene and trans-Isosafrole have been reported to show negligible DPPH activity (EC50 > 1000 %u00b5g/mL) as noted by [15, 16]. This highlights the potential of 1,8-Cineole as the main active component driving the antioxidant properties of the light oil fraction. Further studies should focus on isolating 1,8-Cineole and other active compounds to better understand their individual contributions to the oil%u2019s overall efficacy.4. CONCLUSIONSThis study demonstrated the antioxidant and antiinflammatory potential of the light (LO) and heavy (HO) essential oil fractions from Cinnamomum camphora. The LO fraction exhibited higher efficacy in both activities, likely due to its distinct phytochemical composition dominated by 1,8-Cineole. The presence of additional compounds such as cis-sabinene hydrate acetate, %u03b1-Pinene, trans-Isosafrole, and %u03b3-Terpinene contributes to the oil%u2019s complexity and bioactivity. While the activity of these oils was lower than some synthetic or more potent natural controls, their moderate efficacy and natural origin make them promising candidates for further research. Future studies should aim to isolate and characterize individual compounds especially the major components such as 1,8-Cineole, %u03b3-Terpinene, and %u03b1-Pinene to investigate their
