摘      要：Objective:To reveal the antibacterial,cytotoxicity,larvicidal potentials of Dictyota ciliata ***(***).Methods:Phytochemical,antibacterial screening,cytotoxicity and larvicidal properties of the *** extracts were carried out according to standard *** and larvicidal potentials were analyzed by means of computerized probit analysis ***:The phytochemical screening showed the presence of steroids,alkaloids,phenolic groups,cardiac glycosides,flavonoids and tannins in the crude extracts of *** methanolic extracts of *** showed the highest metabolites presence compared to other tested *** antibacterial activity illustrated that the acetone extracts of *** exhibited the highest zone of inhibition[(10±0.2)mm]against Morganella *** larval mortality(50%)was observed in the crude methanolic extracts of *** against Culex quinquefasciatus(LC_(50)=202.82 mg/L and LC_(90) value is 488.52 mg/L).The result of brine shrimp lethality bioassay showed highest cytotoxicity in methanolic extracts of *** with LC_(50) and LC_(90) values at 340.14 mg/L and 555.58 mg/L ***:The results of the present phytochemical analysis and biological assays will help the manufacturers for identification and selection of raw materials for drug production.
