Assessment of Antioxidant Activity, Total Phenolic and Flavonoid Content of Methanol Extracts From Meyna spinosa

Abstract

The current study investigates the in vitro antioxidant potential, total polyphenolic contents, total flavonoid contents and qualitative phytoconstituent analysis of the methanol extract of the traditionally employed herb Meyna spinosa, by using standard techniques. The results revealed that the methanolic extract of Meyna spinosa is enriched with phytoconstituents such as tannins, terpenoids, alkaloids, saponins, flavonoids, and phenolic compounds. It contains no carbohydrates, fixed oils, or fats. The TPCs of the leaf and stem MeOH extracts were determined to be 92.51 ± 1.87 mg GAE/g and 52.47 ± 0.46 mg GAE/g, respectively. On the evaluation of TFC, the value for the TFC was 63.23±1.12 mg QE/g for leaf extract and 36.48±1.38 for the stems. The DPPH radical scavenging assay evaluated the antioxidant ability of the leaf and stem extracts. The IC50 values of the leaves were 19.88±0.52 μg/ml, and the stems were 52.46±0.67 μg/ml. These findings indicate that methanol extract of Meyna spinosa leaves and stems is a potential source of phytoconstituents which may be helpful to improve health and reduce its adverse effects in food technology, pharmaceutical industries, and ethnopharmacological.
