Screening of Phytochemicals and Antioxidant Potential of Leaves Extract of Litsea glutinosa

摘要

Litsea glutinosa Lour leaves are deliberated as worthy traditional medicine. The aim of this study was to screen the phytochemicals, to evaluate the total flavonoid contents as well as antioxidant activity of various extract of Litsea glutinosa Lour . The phytochemical analysis of each solvent extract was also carried out. Total flavonoid content was determined by aluminium chloride colorimetric assay. Antioxidant activity was determined using 2, 2-diphenyl-1-picrylhydrazyl DPPH , Ferric reducing ability of plasma FRAP and Hydrogen Peroxide H2O2 free radical scavenger methods. Phytochemical screening of various extract revealed the presence of Alkaloids, Flavonoids, Diterpenes, Proteins, Carbohydrate and Saponins. The total flavonoid content was found 1.89, 5.01 and 3.16 mg/100mg of dry weight of pet ether, ethanol and aqueous extract respectively, expressed as Quercetin equivalents. Antioxidant activity was performed using three methods DPPH, Ferric reducing ability of plasma FRAP assay and Hydrogen Peroxide scavenging activity.  Our current results emerged that Litsea glutinosa Lour act as an antioxidant agent due to its free radical scavenging. So, the plant may be further pursued to find out for its pharmacological active natural products.
