PHYTOCHEMICAL COMPOSITION OF SARGASSUM POLYCYSTUM C. AGARDH AND SARGASSUM DUPLICATUM J. AGARDH
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 8
Abstract
Objective: The present study was aimed to reveal the phytochemical composition of Sargassum polycystum C. Agardh and Sargassum duplicatum J. Agardh from Manapad, Thoothukudi district, Tamil Nadu, India.Methods: Seaweeds Sargassum polycystum C. Agardh and Sargassum duplicatum J. Agardh were collected from Manapad, Thoothukudi district, Tamil Nadu, India by hand picking method. The dried and powdered materials (10 g) of S. polycystum and S. duplicatum were extracted with 60 ml of solvents viz., petroleum ether, chloroform, acetone, Methanol and aqueous. The sample was kept in dark for 72 h with intermittent shaking. The different extracts were tested for steroids, terpenoids, alkaloids, phenolic compounds, saponins, tannins, flavonoids, cardiac glycosides, anthraquinone and sterol. Phytochemical screening of extracts was carried out according to the standard method. To know the extractive values and physicochemical characters of S. polycystum and S. duplicatum, the ash and fluorescence analysis was determined by standard method.Results: Among the various tested extracts, methanolic extracts of S. polycystum showed the presence of the maximum of seven metabolites out of ten metabolites examined. Next to that chloroform and acetone extracts of S. polycystum displayed the occurrence of four metabolites. Petroleum ether extract of S. polycystum demonstrated the presence of three metabolites. Aqueous extracts of S. polycystum showed the occurrence of only two metabolites. The methanolic and chloroform extracts of S. duplicatum showed their presence of maximum of five metabolites out of ten metabolites examined. Next to that acetone extract of S. duplicatum displayed four metabolites. Petroleum ether extract of S. duplicatum demonstrated the occurrence of three metabolites in the crude extracts. Aqueous extract of S. duplicatum displayed the presence of two metabolites. The characteristic fluorescent properties or colours emitted by the powdered thallus of S. polycystum and S. duplicatum before and after treating with various extracts were recorded.Conclusion: To strengthen the global scientific effort, in the present study the phyto-constituents presence in S. polycystum and S. duplicatum are documented.Â
