The methanolic extract of Clerodendrum viscosum Vent. (Verbenaceae) was evaluated for in vitro antioxidant activity by determination of total antioxidant capacity, assay of nitric oxide scavenging activity and reducing power test and in vivo antinociceptive effect in acetic acid induced writhing model in swiss albino mice. The results revealed the presence of pronounced antioxidant property as ...

Antioxidant and cytotoxic activities of the methanolic and aqueous extracts of Caesalpinia pulcherrima wood were studied in in vitro models. Both extracts exhibited strong antioxidant activity, as evidenced by the low IC50 values in both 1,1-diphenyl-2-picryl hydrazyl (DPPH), nitric oxide and superoxide scavenging methods; the values were found to be less or comparable to those of gallic acid, ...

ABTRACT The macrocyclic ligands are synthesized by taking etylenediamine and semicarbazide hydrochloride with acetyl acetone respectively in ethanolic medium further their Oxovanadium complexes were synthesized by taking metal salt of type VO (acac)2. Ligands and complexes have been analysed for their physical properties with the help of melting point, molecular weight, conductance , TLC determ...

OBJECTIVE To investigate the antioxidant activities as well as phytochemical constituents of Antidesma thwaitesianum Müll. Arg. leaf extracts. METHODS The leaves of A. thwaitesianum were extracted using three different methods: blending with distilled water, maceration with ethanol and decoction. The chemical antioxidant activity of the plant leaf extracts was evaluated using 2,2-diphenyl-1-p...

Costus speciosus (Koen) J.E. Sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. In the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by DPPH radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

The purpose of this study was to evaluate the cytotoxic and antioxidant properties a hydromethanolic extract Rivina humilis L fruits (HMERH) on human cancer cell lines various in vitro models. HMERH concentrations ranging from 5 400mg/ml were utilized several assay methods such as hydroxyl radicals, DPPH, superoxide radical scavenging activity, metal chelating, nitric oxide test, ABTS, reducing...

BACKGROUND Free radical-induced oxidative stress is the root cause for many human diseases. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. The main objective of the present study was to characterize the antioxidant and antiproliferative potential of rice bran extracted from an important Indian rice variety, Njavara and to compare the ...

Diabetes mellitus is a metabolic disorder characterized by high blood glucose level in the body. It occurs due to inadequate amount of insulin secreted body or resistance receptors. In present study, Baicalein flavone glycoside was evaluated for its effect on alpha-amylase and alpha-glucosidase enzymes using in-vitro assays extracting respective from whole wheat barley combination with in-silic...

A new biflavonol glycoside, quercetin-3-O-β-D-glucopyranoside-(3'→O-3''')-quercetin-3-O-β-D-galactopyranoside (9), together with eight known compounds was isolated for the first time from the leaves of Machilus zuihoensis Hayata (Lauraceae). The structure of compound 9 was elucidated by various types of spectroscopic data analysis. Analysis of the biological activity assay found that compound 9...
