The objective of this study was to evaluate different biological activities of aqueous and ethanolic extracts from Thymelaea microphylla. Antioxidant capacity was determined using two methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, and the inhibition of lipid peroxidation using the β-carotene/linoleate model system. Disc diffusion method was used to evaluate the antibact...

The influence of particle size and extraction solvent on the antioxidant properties of aqueous and ethanolic extracts of tea (Camellia sinensis), ginger (Zingiber officinale), and tea-ginger (2:1) blend was investigated. The powder sizes studied were 0.425, 0.710, and 1.180 mm. Extracts were analyzed for DPPH radical scavenging activity, ABTS radical scavenging activity, total phenol content (T...

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others...

Various extracts including petroleum ether, chloroform, acetone, ethanol, aqueous and crude aqueous of barks of Acacia catechu (A. catechu) Willd (Leguminosae) and the two fractions of ethanolic extract were tested for antihyperglycaemic activity in glucose-loaded hyperglycaemic rats. The effective extract and fraction of A. catechu were subjected to antidiabetic study in alloxan-induced diabet...

A systematic study on the electrochemical behavior of the S-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (ACDA) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. All the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. Controlled potential coulometry gave n=1 per mol...

The present study was carried out to evaluate the hepatoprotective role of leaf extracts of Azadirachta indica A. Juss. Hepatoprotective activities of ethanolic and aqueous extracts of A. indica were examined against carbon tetrachloride induced liver damage in mice using silymarin as control. Enzyme activities of Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transa...

Bauhinia variegata L. is traditionally used in treating a variety of ailments in India. Phytochemical screening and in vitro free radical scavenging activity of aqueous and ethanolic bark extracts of Bauhinia variegata was assessed by studying its ability to scavenge DPPH, Nitric oxide, hydroxyl radical and reducing power. Phytochemical analysis revealed the presence of steroid, phenol/ tannin,...
