The present study reports on the proportion of endocarp, mesocarp and exocarp in green walnuts and on the total phenolic content and antioxidant activity of these fractions and of whole green walnuts (Juglans regia L.). The total phenolic content was determined by the Folin– Ciocalteu method and the antioxidant activity was assessed by the ability to quench the stable free radical 2,2'-diphenyl...

The antioxidant activity and total phenolic content of Sonneratia ovata Back, a mangrove plant, were investigated in this study. Methanol was used to extract the leaf, fruit, stem bark, root S. Back. assay conducted using scavenging radical DPPH, measured following Folin Ciaocalteu method. from leaves Back presented highest than root, fruit. IC50 4.07 mg/L, 25.94 100.94 195.83 respectively. lea...

BACKGROUND Among the potential natural sources of bioactive compounds, those of the macroscopic fungi Phellinus spp. have been identified by previous researches. Phenolic compounds are among the major antioxidant and antimicrobial contributors due to their bioactive properties. AIMS The goal of this study was to determine the total phenolic and flavonoid contents, and its relation with the an...

The present study was to optimize the phenolic recovery from Centella asiatica by investigating the effects of ethanol concentration (0-100%, v/v), extraction time (60-300 min) and extraction temperature (2565°C) on phenolic extraction using single-factor experiments. Total phenolic content (TPC), total flavonoid content (TFC) and condensed tannin content (CTC) were used for determination of ph...

BACKGROUND Flowers of Punica granatum L. (Punicaceae) var. pleniflora, known as "Golnar" in Iranian traditional medicine have been used for the prevention and treatment of foodborne diseases. In this study, antibacterial activities of ethanol extract of Golnar and its fractions were scientifically evaluated against bacteria causing foodborne diseases including Staphylococcus aureus, Bacillus ce...
