In present study, possible radical scavenging activity water (WEB) ethanol extracts (EEB) basil was investigated using different methodologies: 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free scavenging,...

Heavy metal toxicity is one of the major abiotic stresses caused by physiological and biochemical changes. Plants have evolved various phytochemical defense mechanisms to cope with this stress conditions. Phenolic compounds are responses multiple roles in respect adaptation plants environment. In present study, we aimed evaluate differential accumulation phenolics HPLC leaves corn exposed increasing heavy doses plant growth medium. The application Cd, Cu, Pb increased total all treatments...

Abstract This study aimed at evaluating the in vitro antioxidant activity of water and ethanol extracts juniper (Juniperus communis L., Family Cupressaceae) fruit. The properties both Juniper were studied using different assays, including reducing power, free radical scavenging, superoxide anion hydrogen peroxide metal chelating activities. Both exhibited strong total activity. concentrations 20, 40, 60 µg/mL fruit showed 75%, 88%, 93%, 73%, 84%, 92% inhibition on peroxidation linoleic acid...

The ethanol extracts of Morchella vulgaris (EEMV) and esculanta (EEME) were analysed for their antioxidant activities in different systems including reducing power, free radical scavenging, superoxide anion total activity, metal chelating activity. EEMV EEME had similar hydrogen peroxide activity at concentrations 50, 100, 150 microg/mL. These various compared to standard antioxidants such as butylated hydroxyanisole (BHA), hydroxytoluene (BHT), alpha-tocopherol. percent inhibition on...

Echinacea is valuable for its pharmaceutical, medicinal and agricultural properties. Flowers leaves of purpurea (L.) Moench pallida (Nutt.) Nutt. were extracted with methanol, filtered, solvents removed by rotary evaporator to get four separate extracts. The flowers both plants boiled in water then ethyl acetate achieve another Quantifications chemical constituents extracts determined TOF-LC/MS. main compound methanol E. was cichoric acid. Caffeic acid the chief plant flowers. antioxidant...
