Abstract
Caulerpa racemosa know as sea grape is green seaweed that found in the Intertidal Zone of Lhok Bubon, West Aceh but this green seaweed has not yet been utilized by the coastal community. The aim of this study was to determine the antioxidant activity of C. racemosa extract from intertidal zone of Lhok Bubon. In research method, the sample of C. racemosa were collected from Intertidal Zone of West Aceh and crude extracts were prepared using ethanol, ethyl acetate, and n-hexane. The yield and phytochemical assay were measured then followed by the in vitro antioxidant assays and total phenolic content. The result showed the highest yield was found in the methanol (6.07 of percent), followed by ethyl acetate extract (3.79 of percent) and n-hexane (0.75 of percent). C. racemosa crude extract have detected phenolic, flavonoid, saponin and steroid compounds. The antioxidant activity measurement with DPPH method showed the methanol extract had higher activity with value of 26.11 compared than ethyl acetate crude extract with value of 49.42 and n-hexane extract 59.42. It is corroborated with the total phenolic content correlation with antioxidant activity as much as 99 of percent of antioxidant activity contributed from phenolic compound. Some of these bioactive compounds possess a new antioxidant agent with interesting potential for the nutraceutical industry.
