Analysis of Antioxidant in Curcuma Angustifolia Rhizome by 2,2-diphenyl-1-picrylhydrazyl (dpph) Method
Curcuma angustifolia also known as ‘haledo’ is commonly found in Sikkim and has many medicinal uses and has been used traditionally since ancient ages. Its rhizome is aromatic and the solvent extract of the rhizome has free radical scavenging activity which was carried out in this study by 2,2-diphenyl-1-picrylhydrazyl DPPH. Hot methanol extract and cold methanol extract of the dried powder of ...
متن کاملDPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity of flavonoids obtained from some medicinal plants.
A reactive oxygen species has been implicated in a range of human pathological diseases such as atherosclerosis and certain cancers. Flavonoids are reported to exhibit various biological activities, including antioxidative and free radical scavenging activities. Several flavonoids obtained from barley leaves, soybean and some medicinal plants, Silybum marianum, Sophorae Flos, Cinnamon, Ephedrae...
متن کاملExtracts and Constituents of Rubus chingii with 1,1-Diphenyl-2-picrylhydrazyl (DPPH) Free Radical Scavenging Activity
The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity of the fruits of Rubus chingii was studied in vitro. Ethanolic extract, ethyl acetate and n-butanol fractions from dried R. chingii fruits revealed strong DPPH free radical scavenging activity with IC(50) values of 17.9, 3.4 and 4.0 μg/mL, respectively. The ethyl acetate and n-butanol fractions were further purified by a ...
متن کاملA Theoretical Study of 1, 1-diphenyl-2-picrylhydrazyl (dpph) Radical Scavenging Activities of Flavonoids Using Electrotopological State Atom (e-state) Parameters
This study gives a quantitative structure activity relationship (QSAR) correlation of the thirty five flavonoid derivatives having 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities reported by Seyoum et al. The study was performed using electrotopological state atom (E-state) parameter as descriptors. Stepwise regression analysis was used as a chemometric tool. The predictive ...
