Antioxidative Effects of Maytenus Dasyclada Mart. (celastraceae)
Maytenus dasyclada is a trees belonging to the Celastraceae family. The species of Maytenus genus are popularly used to treat gastrointestinal diseases and inflammatory processes as well. The aim of this study was to evaluate the antioxidant activity of hexanic, ethyl acetate and ethanolic extracts from leaves of species, verifying the ability in protect the DNA and remove reactive species , id...
متن کاملStatic magnetic susceptibility of 1.1 diphenyl-2-picryl hydrazyl recrystallized powders
2014 The powder susceptibilities of crystalline stable free radical 1.1-diphenyl-2-picryl hydrazyl and its samples recrystallized from various solvents have been measured at room temperature. The value of static susceptibility has also been evaluated with the help of the data obtained from microchemical analysis of the sample as well as from ESR measurements. The discrepancies in the two values...
متن کاملConsumption of strawberries on a daily basis increases the non-urate 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity of fasting plasma in healthy subjects
Strawberries contain anthocyanins and ellagitanins which have antioxidant properties. We determined whether the consumption of strawberries increase the plasma antioxidant activity measured as the ability to decompose 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) in healthy subjects. The study involved 10 volunteers (age 41 ± 6 years, body weight 74.4 ± 12.7 kg) that consumed 500 g of strawberri...
متن کاملA comparative chemical study of Maytenus ilicifolia mart. reiss and Maytenus robusta reiss (Celastraceae).
This work describes a comparative qualitative and quantitative chemical analysis of Maytenus ilicifolia and Maytenus robusta (Celastraceae), extracts by high-resolution gas chromatography (HRGC), using external standards as the method of determination and thin layer chromatographic (TLC). The results show that both plants have a similar chromatographic profile. However, M. robusta exhibited abo...
متن کاملEffects of Salviae Miltiorrhizae Radix Hot Aqueous Extract on Nitric Oxide and Prostaglandin E2 Production and on 1,1-diphenyl-2-picryl hydrazyl Radical Scavenging in Macrophages
OBJECTIVES The objective of this study is to investigate the effects of Salviae Miltiorrhizae Radix hot aqueous extract on nitric oxide (NO) and prostaglandin E2 (PGE2 ) production and on 1,1-diphenyl-2-picryl hydrazyl (DPPH) free-radical scavenging in macrophages. METHODS Salviae Miltiorrhizae Radix(300 g) was heated at 100℃ with distilled water (2 L) for 4 hours. The extract was filtered an...
