This study investigates the total phenolic and flavonoid contents, antioxidant activity, and metal chelation capacity of acetone and water extracts from Anethum graveolens L.. The total phenolic content of the acetone extract was significantly higher (173.49 ± 4.91 µg GAE/mg extract) than the water extract (98.52 ± 3.62 µg GAE/mg extract). Similarly, the flavonoid content of the acetone extract (72.81 ± 1.15 µg QE/mg extract) exceeded that of the water extract (27.69 ± 1.72 µg QE/mg extract). Concentration-dependent responses revealed higher antioxidant activity for the acetone extract across

The emulsifying and demulsifying abilities of ethanol, n-hexane and distilled water extracts of Gmelina arborea leaves in oil-in-water phase was investigated. Quantitative and qualitative phytochemical analyses of the extracts were done by GCMS method. The results obtained showed the presence of many bioactive compounds like saponins, alkaloids, flavonoids, tanins etc. The emulsification and demulsification tests were carried out at different volume concentrations of the extract and different time, using total volume of water separated as the yard stick.

Abstract A cyclic reheat system for a wet flue gas desulfurization system extracts heat from the inlet flue gas and transfers this heat to the outlet flue gas. One method of achieving this uses tube-type heat exchangers in the inlet and outlet gas streams with a fluid (e.g., water) circulated between them. For high sulfur coal, questions of materials selection and cleaning methods of the inlet heat exchanger exist because of the potential for acid condensation. An inlet gas heat exchanger test apparatus was built and installed on a slipstream from a high-sulfur coal-fired power plant. Results

Abstract The chemical, physical-chemical and electrochemical properties of a soil characterize its corrosivity, and external factors determine its relative aggressivity. Buried structures are subject to corrosion and the intensity of the process is related to the aggressivity of the soil. Several parameters such as resistivity, pH, water retention capacity and the presence of soluble salts are characteristics that indicate the corrosivity. In this work, several experimental techniques have been used to analyze soil samples collected in different regions of Rio de Janeiro, considering mountain

Abstract A cyclic reheat system for a wet flue gas desulfurization system extracts heat from the inlet flue gas and transfers this heat to the outlet flue gas. One method of achieving this reheat uses tube-type heat exchangers in the inlet and outlet gas streams with a fluid (e.g., water) circulated between them. For plants burning high sulfur coal, questions of materials selection and cleaning methods of the inlet heat exchanger exist because of the potential for acid condensation. An inlet gas heat exchanger test apparatus was built and installed on a slipstream taken after the precipitator

The flowers of Tyoha augustifolia were extracted with 70% methanol and distilled water in comparison. When the aqueous extracts obtained from both methanol and distilled water were tested for their effect on germination of the seeds of Mimosa pigra, the results showed inhibition by both extracts. Evidences from chemical tests and absorption spectra suggested presence of condensed tannins in both aqueous extracts. The addition of 10% bovine serum albumin to the aqueous extracts from both water and 70% methanol resulted in light brown precipitates. When the seeds of Mimosa pigra were grown in th

Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was

J2 labelled with radioiodine and biotin released 125I and biotin-labelled molecules into water after 20 hours incubation, indicating that SC proteins may be loosely attached to the nematode.
