Abstract

Kelakai is known as traditional remedy for treating several diseases, such as fever, anemia, and stimulate the production of breast milk for breastfeeding mother. Instead of those benefits, kelakai also proved has several kinds of antioxidant properties. Therefore, extracting antioxidant properties from kelakai is one way to discover the amount of antioxidant activity contained in kelakai. In this research, the multiplestage extraction process was done in order to optimize the antioxidant activity. Moreover, based on data obtained from single stage extraction process, the most suitable condition was discovered. It turns out that the use of milled sample in water solvent for 12 hours at 44oC produce the highest antioxidant activity, which is 4599.76 ppm to inhibit 50% of DPPH.. Referred to the experiment, the antioxidant activity of the extract which gained from multiple-stage was higher than from single stage. Multiple-stage process has proven the increasing of antioxidant activity up to 72.43%, which is needed 2020 ppm to inhibit 50% of DPPH.
