Abstract 1. Nowadays, seaweeds have been considered as sources of bioactive compounds used for antioxidant and anti-pathogen in medical experiments and cosmetic ingredients including used as elicitor for induced resistance in agricultural sciences. Acanthophora spicifera is a non-valuable red seaweed that can be found in Andaman sea and gulf of Thailand. In this study, we have used this red seaweed to search for its bioactive compounds that could be served as alternative sources. Two methods were compared between extracted with hot water and methanol. Using hot water, we obtained high content of phenolic
2. in contrast, using methanol gave high amount of flavonoid. The phenolic content using hot water was 3.42 mg gallic acid equivalent/g dry weight and flavonoid content extracted with methanol was 2.93 mg rutin equivalent/g DW. We measured in vitro antioxidant activities using DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (ferric reducing antioxidant power) methods. For DPPH, the IC50 of DPPH scavenging activity using hot water and methanol were 7.33 mg and 25.32 mg, respectively. For FRAP, the hot water extract had reducing activity higher than the methanol extract which were 8.08 and 4.66 mg ascorbic acid equivalent/g DW, respectively. In conclusion, the hot water extract had antioxidant activity higher than the methanol extract. These results provided the evident of using low cost extraction method but obtained higher amount of active compounds
3. consequently, could up value of this non-valuable seaweed. The ABTS Scavenging of (2,2-azinobis-(3ethylbenzothiazoline-6-sulfonic acid)) activity, anti-tyrosinase and antibacterial activities will be further conducted before applying these active compounds on food and cosmetic industries.
