Antioxidant activity of young leaves extracts of Lygodium microphyllum on boiling variation

Abstract

Lygodium microphyllum is one of the ferns that is often used as raw material for food and traditional medicine. L. microphyllum as food ingredients are usually used in the young leaves. This study aims to determine the antioxidant activity of the young leaves extracts of L. microphyllum by boiling variations.The research method is a pure experiment by extracting the young leaves of L. microphyllum by boiling with variations in temperature (30, 40, and 50°C) and boiling time (10, 15, and 20 minutes).The results showed that boiling at a temperature of 50°C and a boiling time of 20 minutes had the highest antioxidant activity with IC50 99±1.23 μg/mL.
