摘要
Objective:To deal with the assessment of the chemical composition of carbohydrate,protein,phenol,flavanoid,chlorophyll,and carotenoid and antifungal activity of various marine seaweeds collected from Okha coast,Gujarat during September,2013.Methods:Biochemical compounds of selected seaweeds were quantified and antifungal activity of these species belonging to red,green,and brown seaweeds was explored and the seaweeds were extracted in acetone,ethanol and chloroform.Results:The carbohydrate content was highest inCystoseira indica Mairh,protein was highest inGracilaria corticataJ.Agardh and phenol content was highest inPadina boergesenii;flavanoid content was found greater inCystoseira indica,chlorophyll content was found greater inMonostroma latissimum Wittrock and carotenoid content was more inDictyopteris acrostichoides Bornet.The highest inhibiting effect was noted forSargassum tenerrimum J.Agardh andTurbinaria ornata J.Agardh belonging to brown algae,againstAspergillus niger andPenicillium janthinellum in chloroform extracts and ethanolic extracts,which caused opportunistic infection ofHIV-infected person,lung disease,aspergillosis,and otomycosis(fungal ear infections).Conclusions:The study reveals that the seaweeds contain high amount of biochemical constituents.Besides,the crude extracts of the seaweeds showed promising activity against the tested fungal pathogens.Therefore,seaweeds collected from Okha coast,Gujarat region are biochemical compounds with potential capacity which make them useful for screening natural products for pharmaceutical industry.
