Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

The study investigated the Phaeophyceae during year 2019 at sixteen sampling sites representative for Cham islands. Specimens were collected by scuba diving, snorkelling and walking upper tidal zone in both dry rainy seasons. Twenty-five species of identified islands from four orders, families eleven genera. Sargassaceae family is most abundant composition, followed Dictyotaceae, Scytosiphonace...

The present study aimed to find the toxicity of aqueous and methanol extracts three different brown macroalgae viz., Padina tetrastromatica, Sargassum wightii Turbinaria conoides against tobacco cutworm, Spodoptera litura. Larval mortality was noticed in both at all concentrations tested a dose-dependent increase after 96 h exposure with 73.33, 56.66, 50.00 per cent extract; 50.00, 46.66 43.33 ...
