Abstract
Many active chemical substances are synthesized from plants especially medicinal plants; some substances of them produce important pharmacological effects on various physiological systems of organisms. In this study, ethanolic extract of whole part of the plant Spilanthes calva (Family- Asteraceae) was taken to explore phytochemicals and antioxidant activities. The phytochemical research of the plant extract exhibited the existence of glycosides, tannins, carbohydrates, flavonoids, alkaloids gums, phenolic compounds, steroids, proteins & amino acids, acidic compounds etc. The percentage yield of extract was found to be 1.54% w/w. In DPPH Free Radical Scavenging Assay, the IC50value of extract was 32.42 µg/ml where the IC50 value of ascorbic acid (standard antioxidant) was 12.90 µg/ml. Ethanol extract showed considerable total phenolic content(TPC) of 459.89 mg GAE/gm of dry extract by using Gallic acid calibration curve, total flavonoid content(TFC) of 123.59 mg QE/gm of dry extract by using Quercetin calibration curve and total tannin content (TTC) of 22.83 mg GAE /gm of dry extract by using Gallic acid calibration curve. The above study suggests that the plant may be an important source of natural products of health benefits.
