<br/><br/> Objective<br/>: <br/>Phytochemical is naturally present in the seaweeds which biologically play a<br/>significant role. The intention of this study was designed to <br/>screen the phytochemical constituents and antimicrobial potential of selected seaweed collected from Rameshwaram and Tuticori<br/>n Southern coast <br/>of India.<br/>Method<br/>s: <br/>The  present  study  investigated  the  presence  of  phytochemical  constituents  and<br/>  also <br/>total  phenol,  total  carbohydrate  and  total  protein  <br/>quantity  of  the  brown  seaweed.  <br/>Dictyopteris <br/>delicatula<br/>,<br/>Padina  gymnospora<br/>,<br/>Acanthophora  spicifera<br/>,<br/>Portieria<br/>hornemannii<br/>and<br/>  Ulva <br/>faciata<br/>were <br/>extracted with solvents having different polarities like<br/>methanol, ethanol, chloroform and water and screened for the phytochemical constituents, <br/>total  phenol,  total  carbohydrate,  total  protein  and  DPPH  with  standard  procedure.  The  antibacterial  activities  of  the  seaweed<br/>s  were  examined  by  <br/>agar well diffusion met<br/>hod.<br/>Result<br/>s: <br/>Among the five seaweeds, <br/>U. <br/>faciata<br/> showed the maximum number of active constituents in the methanol extract likewise <br/>P.  gymnospora<br/>was  found  to  have  a  number  of  diligent  compounds  in  ethanol  extract.  <br/>A.  spicifera<br/>showed  minimum  compounds  in  ethanol  as  well  as  chloroform  <br/>extract. Moreover <br/>A. spicifera<br/>, <br/>P. <br/>hornemannii<br/> have shown <br/>the <br/>superior<br/> quantity of protein and carbohydrate when compared to other species. The <br/>scavenging activity of methanol extracts at 5 mg<br/>/ml<br/> concentration <br/>P. hornemannii<br/> shows 18.2% and<br/>A. spicifera<br/> possess 17.1%. In the antibacterial <br/>activity,  methanol  extracts  of  all  the  seaweed  showed  <br/>a <br/>potential<br/>  inhibitory  activity  against  <br/>B<br/>.  c<br/>ereus<br/>and <br/>P.  a<br/>eruginosa<br/>  compared  to  other  <br/>pathogens.
