Abstract
The species H. micronesica and H. macroloba are a group of green seaweed (Chlorophyta) which are found in the waters of Pulau Maspari. The purposes of this study was to analyze the activity of antioxidant and phytochemicals compounds of the active extract of seaweed H. micronesica and H. macroloba originate from the Maspari Island. The procedures in this study include; collecting and handled samples, stratified maceration both samples using a solvent ethyl acetate (Hmi-EA and Hma-EA) and methanol (Hmi-M and Hma-M), extraction, antioxidants test with DPPH, phytochemical test and analysis IC 50 . The results showed that of the four extracts tested contained an extract that had the ability to inhibit free radicals which extract Hmi-EA. Active extract Hmi-EA had a value of IC 50 52.81 ppm. Active extract Hmi-EA contained alkaloids, steroids and flavonoids. Hmi-EA extract will be highly potential as an antioxidant.
