Preliminary phytochemical analysis of the ethanolic extract of brown Seaweed Sargassum wightii

Abstract

The big stores for the favorable algae are the Seas and Oceans and the study of seaweeds is called as phycology or ecology. The identification and isolation of new substances are growing from the source of marine organisms. The seaweeds live in salty water and are eukaryotic organisms considered as a good source of bioactive natural products. The present study investigated to explore the phytochemical constituents of the seaweed Sargassum wightii (Brown algae). The brown marine algae “Sargassum wightii” belongs to the family “Phaeophyceae”. Ethanol was used as a solvent system for the preparation of the extract of Sargassum wightii. The ethanolic extracts of Sargassum Wightii were undergone to the qualitatively phytochemical test by means of typical measures. Phytochemical analysis shows the presence of alkaloids, tannins, steroids, flavonoids, and carbohydrates, whereas proteins, free amino acids and saponins were found to be absent. The results of the study may lead a foundation for the further studies on this marine algae Sargassum wightii.
