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.
