The larvicidal activities to determine the efficacies of acetone, ethyl acetate, chloroform and butanol dried leaf extracts of Annona squamosa, Cynodon dactylon, Melia azedarach and root extract of Hemidesmus indicus tested against 3 instar Culex quinquefasciatus and Aedes aegypti. The highest larvae mortality was found in the acetone followed by ethyl acetate, chloroform and butanol extract of...

In the present investigation the acetone extracts of three marine macroalgae Laurentia obtusa, Codium elongatum and Cutleria multifida were tested for antioxidant, antimicrobial and cytotoxic potential. Antioxidant activity was evaluated by free radical scavenging, superoxide anion radical scavenging and reducing power. C. elongatum extract had most potent free radical scavenging activity (IC50...

The first paper of this series (Roy, 1953) reported the presence of two distinct fractions exhibiting sulphatase activity in an aqueous extract of an acetone powder of ox liver, and gave preliminary data on the properties of the two crude enzymes, which were separated by fractional precipitation with acetone. The present paper describes the further purification and properties of fraction A, now...

Extracts of acetone powders of Flavobacterium heparinum which have been adapted to heparin catalyze a rather extensive degradation of this mucopolysaccharide. This ‘Lheparinase” activity is due to the presence in the extract of a sulfamidase, a sulfesterase, and at least one glycosidase (1, 2). Such extracts also catalyze the hydrolysis of hyaluronic acid and chondroitin sulfate. This paper com...

The aim of this study was the use and revalorization two persimmon by-products A B generated in juice production process. by-product resulting from a pectinase enzymatic treatment peels pulp to optimize extraction especially suitable for recovery valuable bioactive carotenoids. solvents solvent combinations used were: ethanol, acetone, ethanol/acetone (50:50 v/v) ethanol/acetone/hexane (25:25:5...

Mosquito-borne diseases have an economic impact, including loss in commercial and labor outputs, particularly in countries with tropical and subtropical climates; however, no part of the world is free from vector-borne diseases. Vector borne diseases are major sources of illness and death worldwide. Mosquitoes are primary vectors for many dreadful and fatal diseases. Culex quinquefasciatus is t...

The cuticular lipid compounds, usually named waxes, present in the layering of Quercus suber adult leaves were extracted with solvents different polarities (n-hexane, dichloromethane and acetone) analysed by GC–MS. Q. have a substantial wax layer (2.8% leaf mass 239 μg/cm2), composed predominantly terpenes (43–63% all compounds), followed aliphatic long chain molecules, mainly fatty acids, smal...

Synergistic activity of Salvia officinalis and Cichorium intybus extracts and commonly used antibiotics, amoxicillin and chloramphenicol, were evaluated. Interactions between plant extracts and antibiotics were tested by checkerboard method and interpreted as FIC index. Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and clinical isolates Staphyl...

In this study, it was aimed to compare the antioxidant properties of extracts obtained from extraction olive leaves in Hatay province prepared with different solvents. For purpose, were extracted using pure methyl alcohol soxhlet and also by maceration 60% ethanol, 70% methanol, 90% acetone (v/v) distilled water. Total Flavonoid Content (TFC), Phenolic (TPC), Ferric Antioxidant Reducing Power (...
