【 摘 要 】

Free radicals are highly reactive molecules due to unpaired electron in their outer orbital. Excess of free radicals inside human body as consequences of environmental exposure such cigarette smoke may lead to degenerative diseases such as diabetic, cancer etc. This negative effect can be limited by the utilization of natural antioxidant substances, especially produced from plant. Avicennia alba dan A. marina are mangrove species that widely distributed in Indonesia and are expected potential as antioxidant. The objective of this study is to evaluated Avicennia alba dan A. marina potency as antioxidant performed with DPPD (1,1-diphenyl-β-picryl hydrazyl) method. Leaf and bark of Avicennia alba dan A. marina were collected from Nguling District, Pasuruan, East Java. Results shows that based on 50% inhibition Concentration (IC50), Avicennia alba leaf were categorized had a very high antioxidant potential (IC50 14,85 ppm) whereas the bark were categorized had a weak antioxidant potential IC50 167,17 ppm). For A. marina, the leaf were categorized had a moderate antioxidant (IC50123,23 ppm) whereas the bark were categorized had a weak antioxidant potential (IC50198,15 ppm).
