In the present study, various mixtures of aqueous ethanol and acetone solutions were utilized to extract anthocyanins from eggplant peel by a discontinuous process to obtain a natural red-purple colorant. First, the most appropriate combination for extraction solvent was selected as ethanol 70 wt in water acidified with acetic acid 3 wt, which was determined by analysis of extraction yields and...
One of the main components of lung alveoli is surfactant. DPPC (Dipalmitolphosphatidylcholine) is thepredominant lipid component in lung surfactant that is responsible for lowering surface tension in alveoli in thisarticle. We used a very approximate model with computational method of Ab initio to describe the interactionsbetween DPPC as important component of lung surfactant and some chemical ...
Workers are commonly exposed to mixtures or combinations of chemical agents, and these mixtures often consist of solvents. One group of solvents that has been extensively studied for its neurotoxic properties has been the ketones. However, previous research has focused on neuropathies produced by extended exposures and not on the simple pharmacokinetics or the reversible central nervous system ...
Background: This study was devoted to assessing the inhibitory potential of acetone, methanol, and ethanol extracts of Acroptilon repens against disease-associated enzymes, as well as their antioxidant/antibacterial activity and phytochemical composition. Methods: Comparative assessment using various antioxidant evaluation methods, including ferric reducing antioxidant power, scavenging ability...
This study aims to evaluate the effects of solvents extraction and drying methods on selected fucoxanthin content in Sargassum polycystum that was collected from Blue Lagoon, Port Dickson Malaysia. Two different were used this study, i.e sun-drying air-drying. Acetone, methanol ethanol as extract S. polycystum. The results showed both had a statistically significant effect (p < 0.05) Among thre...
Medicinal plants have assumed the basis of traditional medicine and proven effective in human health care across world. There is a growing interest role complementary alternative medicines to treat various illnesses. The continued consumption antibiotic with little or no impact on bacteria negatively affected delivery. Bitter leaf (Vernonia amygdalina) popular shrub belonging family Asteraceae ...
Background: In acetone-butanol-ethanol (ABE) fermentation by Clostridium acetobutylicum ATCC 824 using corn-based substrate, the solvents are generally produced at a ratio of 3:6:1 (A:B:E, w/w). Results: A higher butanol/acetone ratio of 2.9:1 was found when cassava was used as the substrate of an in-situ extractive fermentation by C. acetobutylicum. This ratio had a 64% increment compared to t...
