The anti-inflammatory, antioxidant, and antimicrobial properties of artemisinin derived from water, methanol, ethanol, or acetone extracts of Artemisia annua L. were evaluated. All 4 artemisinin-containing extracts had anti-inflammatory effects. Of these, the acetone extract had the greatest inhibitory effect on lipopolysaccharide-induced nitric oxide (NO), prostaglandin E2 (PGE2), and proinfla...

Metallic monoliths were prepared by anodized aluminum-scale pilot plant, using sulfuric acid as electrolyte. Anodisation tests were conducted at different times and different temperatures of the electrolytic bath. Aluminum monolith anodized at 40oC for 30 min was selected for catalysts support. The monoliths were impregnated by two methods: i) impregnation in two stages using two Mn salts in an...

The antioxidant activities and phenolic contents of mulberry leave extracts obtained by aqueous mixture acetone, ethanol methanol were determined. Both alkaline hydrolysis acid used to extract bound phenolics. HPLC was determine the profile extracted Three experimental assays, namely, Fe3+ reducing power (FRAP), ABTS- DPPH-radical scavenging activity, employed characterize their activity. This ...

The Lowry method and a capillary electrophoresis method were used to analyse protein residues in the supernatant after solvent deproteination of plasma. Acetonitrile and acetone were much more effective than methanol and ethanol at reducing the levels of proteins in plasma. The ability of different solvents to decrease levels of phospholipids in plasma samples was assessed using electrospray io...

Dried stem bark extracts of Saraca asoca Roxb. Prepared by different extraction methods (Soxhlet, Ultrasonication assisted & Microwave assisted extraction) with ethanol 90%, ethanol 60% and acetone. The acetone extract prepared by Ultrasonication assisted extraction, showed significant antidiarrhoeal property in castor-oil induced diarrhoea in albino rats at a dose of 200 mg/kg, b.w. as compare...

cluster ions is a function of cluster size with reactivity decreasing as cluster size increases. Ethanol cluster ion distributions that formed at atmospheric pressure from 24 ppbv, 900 ppmv, and 1% ethanol/N2 gas mixtures were studied. Small (C2H5OH)nH + clusters, those formed using the 24 ppbv ethanol/N2 mixture, react at or near the collisional rate with DMSO, NH3, acetone, and methyl vinyl k...

conclusions in this study, we isolated b. licheniformis producing an organic solvent-stable protease from oil-contaminated soil. the protease was stable and active in various organic solvents. by purification, the protease could be used as a biocatalyst for organic solvent-based enzymatic synthesis. results according to 16srdna sequencing, strain isa9 was identified as a new strain of bacillus ...

The development of tools for genetic manipulation of Clostridium ljungdahlii has increased its attractiveness as a chassis for autotrophic production of organic commodities and biofuels from syngas and microbial electrosynthesis and established it as a model organism for the study of the basic physiology of acetogenesis. In an attempt to expand the genetic toolbox for C. ljungdahlii, the possib...
