Abstract

This study investigates the effectiveness of natural extracts from avocado leaves (Persea americana) as antioxidants in biodiesel. The oxidative stability of biodiesel supplemented with these extracts was evaluated in comparison to synthetic antioxidants such as BHA and BHT. The results demonstrated that the ethanolic extract of avocado leaves exhibited the longest induction time, suggesting its potential as a natural substitute for synthetic antioxidants.
