| Abstract | ||
| Phlorotannins are a group of complex polymers of phloroglucinol which are unique compounds from marine brown algae. In the present study, Phlorotannins polyphenol compounds have been extracted from Sargassum linifolium brown alga and identified by FT-IR and UPLCMS/ MS. Moreover, the total phenolic content was determined by the Folin–Ciocalteu assay. The results demonstrated the presence of poly phenolic compounds in the extract with higher levels about (22.19 ± 3.42) mg / gram gallic acid. In addition S. linifolium phlorotannins extract showed higher antioxidant activity about 63.56 mg/g dry weight. Also, the bactericidal activity of phlorotannins extract has been examined against food-borne pathogenic bacteria. The result showed that phlorotannins has higher bacteriostatic activity, which lead to bacterial growth inhibition and bacterial death .These results suggested that S.linifolium phlorotannins extract could be utilized as a good source of antimicrobial agent in pharmaceutical industry. | ||
