Chemical Composition, Bioactivity, and Thermal Properties of Buckthorn Seed Oil

Material science and Engineering

This study focused on the chemical composition, thermal properties, antioxidant, and antimicrobial activities of buckthorn seed oil. The GC/MS analysis identified twelve compounds, with cis-Vaccenic acid (20.39%) and 9,12-Octadecadienoic acid (Z,Z) (18.71%) as dominant constituents. Heating caused significant transformations, including the formation of Trilinolein (20.77%). Antioxidant activity, measured using the DPPH method, showed a moderate % Radical Scavenging Activity (%RSA) of 70.5%, compared to 90.5% for the synthetic control, Propyl Gallate. Antimicrobial tests indicated low sensitivity against Staphylococcus aureus and resistance to Escherichia coli and Candida albicans, suggesting limited antimicrobial efficacy. DSC analysis revealed a melting point near 40°C and thermal stability up to 150°C, followed by additional endothermic transitions. These findings suggest that buckthorn seed oil has promising applications in food processing, cosmetics, and pharmaceuticals, although its antimicrobial activity may require further enhancement for broader use.
