Abstract
This study intended to conduct a qualitative phytochemical test and an antioxidant assay on Lansium domesticum seeds grown in the Philippines. The seeds were extracted through maceration in methanol, ethyl acetate, and hexane. The antioxidant activity of the seeds were tested by measuring the absorbance of the free radical, 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonate) or ABTS through the use of a UV/Vis spectrophotometer. The results were measured in % free radical scavenging activity, using 2% [g/ml] Vitamin C in distilled water as the positive control.
