ABSTRACT:
The seaweed is a large and diverse group of marine macro algae that can be found in intertidal and sub tidal coastal regions around the world.Seaweed are simpler in their structural composition because they take up the nutrients into their blades or fronds directly from the seawater, unlike more complex land plants which take up the nutrients through their roots.There are three different types of marine macro algae–red algae (Rhodophyta), brown algae (phaeophyta), green algae (chlorophyta). They are grouped according to their unique photosynthetic pigments, which give them their characteristics color and unique properties. Secondary metabolites from natural resources are a potential source that leads and drugs can exploited to combat antimicrobial resistance in microorganisms. The present study investigated to explore the preliminary phytochemical constituents of marine red and brown seaweed such as Gracilaria corticata, Gracilaria edulis, Saragussum wightii wherelse Methanol, Acetone and Aqueous were used as a solvent system for the preparation of the extract.
