Biomolecules can be oxidized by free radicals. This oxidative damage has an important etiological role in aging and the development of diseases like cancer, atherosclerosis, and other inflammatory disorders. Synthetic antioxidants, like butylated hydroxyanisole, are good free radical scavengers, however, the synthetic antioxidants can be carcinogenic. Therefore, there is an increasing interest ...

in the present study the volatile organic compounds of e. azerbaijanica rech.f. were identified. phytochemical assessment of meoh extract of aerial parts of this plant was also performed and its free radical scavenging properties was evaluated. the essential oil of the air-dried aerial parts was obtained by hydro-distillation using a clevenger type apparatus. the oil was then analyzed by gas ch...

BACKGROUND S. sylvestre Wright is an extremely rare plant, found only in the sub-Himalayan Terai region of West Bengal and neighboring Sikkim foot-hills. The plant has never been evaluated for any pharmaceutical properties. The phytochemical status of the plant is still unknown. Therefore, the aim of the study was to explore the antioxidant and free radical scavenging activities and analysis of...

Tagetes mendocina (Asteraceae) is a medicinal plant widely used in the Andean provinces of Argentina. Preliminary assays showed free radical scavenging activity in the methanol extract of the aerial parts, measured by the decoloration of a methanolic solution of the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and scavenging of the superoxide anion. Assay-guided isolation led to 4'-hydroxyaceto...

The study explored on the commonly available weed plant Commelina nudiflora which has potential in-vitro antioxidant and antimicrobial activity. The different polar solvents such as ethanol, chloroform, dichloromethane, hexane and aqueous were used for the soxhlet extraction. The extracts were identified pharmacologically as important bioactive compounds and their potential free radical scaveng...

The air dried powdered plant materials were extracted with different organic solvents, screened for phytochemicals and analyzed for their biological activities. The antioxidant potential was evaluated by scavenging of DPPH radical, TPC and TFC, while antimicrobial activity by disc diffusion assay against a set of bacterial and fungal strains. Ethylacetate extracts showed higher free radical sca...

background cancer is one of the leading causes of human death. the discovery of new generations of low-cost anticancer drugs with high efficacy and low toxicity is necessary, and is only possible by screening medicinal plants with prior knowledge. objectives in this study, the bioactivities of three medicinal plants from india, including alstonia scholaris, alstonia venenata, and moringa oleife...

Background and objectives: Phlomis olivieri Benth. (Lamiaceae) is a medicinal plant widely distributed in Iran. In the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. Methods: Silica gel (normal and reversed phases) and Sephadex LH-20 colu...

The present study was aimed at evaluating the antioxidant activities of Cordia dichotoma known for their medicinal properties in folk medicine. In an effort to reduce the undesirable consequences of synthetic food conservatives in human health and food industries, scientists have recently changed their interest to search new conservatives. Antioxidants are important inhibitors of lipid per-oxid...

Varied medicinal plants are known as a source of natural phytochemicals with antioxidant activities that can protect organisms from oxidative stress and from various chronic diseases. Papaver rhoeas has a long history of medicinal usage, especially for ailments in adults and children. The possible cytotoxicity, genotoxicity and potential antioxidant effect of plant extract isolated from flowers...
