The present study was carried out to evaluate the antimicrobial and antioxidant activities of methanol extract of Careya arborea (MECA) stem barks (Myrtaceae) in various in-vitro systems. Antimicrobial activities of MECA were carried out using disc diffusion methods with Gram positive and Gram negative bacteria and some fungal species. MECA showed broad-spectrum antimicrobial activity against a...

The present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of Ervatamia coronaria leaves (Apocynaceae) in various systems. DPPH radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. The antioxidant activity of methanolic ex...

Purpose: To investigate the cytotoxic and antioxidant activities of the fruit and fruit waste (residue and marc) extracts of Antidesma thwaitesianum Müll. Arg., known as mamao in Thai, using chemical and cell-based assays. Methods: The cytotoxicity of mamao fruit and fruit waste extracts obtained by expression, maceration and decoction against a panel of six human cancer cell lines (COR-L23, A5...

IH-901 (20-O-β-D-glucopyranosyl-20(S)-protopanaxadiol or compound K) is a final intestinal bacterial metabolite of ginseng in humans. It has various pharmacologic effects such as antiaging, immunopotentiation, antistress, and antimetastatic activities. We analyzed the antioxidant activities of IH-901 using several assays including: total antioxidant activity, reductive potential, 1,1-diphenyl-2...

Methanolic extract of Jasminum mesnyi Hance leaves having antidiabetic activity was subjected to fractionation to obtain antioxidant and antihyperglycemic rich fraction. Different concentrations of ethyl acetate and n-butanol fractions were subjected to antioxidant assay by DPPH method, nitric oxide scavenging activity and reducing power assay. The fractions showed dose dependent free radical s...

Mallotus philippinensis is an important source of molecules with strong antioxidant activity widely used medicinal plant. Previous studies have highlighted their anticestodal, antibacterial, wound healing activities, and so forth. So, present investigation was designed to evaluate the total antioxidant activity and radical scavenging effect of 50% ethanol fruit glandular hair extract (MPE) and ...

Introduction: punicalagin, a hydrolysable tannin polyphenol from pomegranate, reported to have a protective effect against many diseases due to its high antioxidant and free radical scavenging activities. Aim, this study investigated the potential antihypertensive activity of punicalagin in human derived EA.hy926 endothelial cell model, via two mechanisms. In first mechanism, punicalagin enhanc...

The objective of the study was to investigate the anti-oxidant and anti-inflammatory effect of aqueous extract of Ocimum sanctum leaf. The antioxidant and anti-inflammatory activities were evaluated using in vitro Ferric reducing power, Free radical scavenging activity by DPPH method, hydroxyl radical scavenging activity, Nitric oxide radical scavenging activity, Hyaluronidase inhibition assay....

Methods: The antioxidant potential of pyrrolo [1, 2-A] pyrazine-1, 4-dione, hexahydro-3-(2-methylpropyl) (diketopiperazine) extracted from Streptomyces sp. VITMK1 was studied using reducing power assay. The scavenging of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical and nitric oxide (NO) radical by the compound was also studied. The cytotoxic activity of the compound on RAW 264.7 macrophage cel...
