Abstract

 it contains polysaccharide compound. This research aims to isolate and examine the activity of antioxidant and toxicity of polysaccharide extract and fraction fromred algae Gracilariaverrucosa. The study was carried out by isolating the polysaccharide extract using aqueous 100 o C and methanol-ethanol precipitation .Purification of polysaccharide done by Column Chromatography DEAE-Cellulose and analysis polysaccharide concentration was using phenol-sulfuric acid. Antioxidant activity of crude extract and polysaccharide fraction was examined using DPPH method, and toxicity test was carried out using Brine Shrimp Lethality Test (BSLT). The research results reveals that the highest polysaccharide concentration was fraction 7 with value of 0,267 mg/mL, and  the crude extract and fraction  4 have strongest antioxidant activity with IC50 values of 51,22 and 62,25 ppm, respectively. The result of BSLT assay showed that the crude extract and fraction 6 has a highest toxicity with LC50 values of 47,73and 58,48 ppm, therefore it is classified as toxic. The polysaccharide of crude extract and fraction 7 has a potential to be developed as an alternative antioxidant and antitumor agent. Identification with FT-IR shows the characteristic bands of agarocolloid.

Abstract

Red algae Eucheuma cottonii and Eucheuma spinosum which one alternative source of antioxidant and anticancer because contains polysaccharide compound. This research aims to isolate and examine the activity of antioxidant and toxicity polysaccharide extract from red algae Eucheuma cottonii and Eucheuma spinosum . The study was carried out by isolating the polysaccharide extract using water and methanol-ethanol precipitation. Antioxidant activity of crude extract was examined using 1,1-Difenil-2-pikrilhidrazil (DPPH) method, and toxicity test was carried out using Brine Shrimp Lethality Test (BSLT). The research results showed that the crude extract polysaccharide for Eucheuma cottonii and Eucheuma spinosum have strong antioxidant activity with IC50 value of 72,49 ppm and 75,98 ppm. The result of BSLT assay showed that the crude extract polysaccharide has a highest toxicity with LC50 value of 165,88 ppm and 337,21 ppm there are classified as toxic. The crude extract polysaccharide Eucheuma cottonii and Eucheuma spinosum has a potential to be developed as an alternative antioxidant and anticancer agent.
