Investigation of cytotoxicity and in-vitro antioxidant activity of Asparagus racemosus root extract

This attempt is made to address the phytoconstituents, free radical scavenging activity and brine shrimp lethality bioassay of five different extracts of Asparagus racemosus roots. Preliminary phytochemical examination of the crude extracts of Asparagus racemosus root disclosed the existence of different sort of chemical groups such as flavonoids, tannin, saponin, alkaloids, carbohydrate. The root displayed significant DPPH free radical scavenging activity with highest IC50 value showed by ethanol extract with a value of 78.15 µg/ml followed by methanol and petroleum ether having value of 106.44 µg/ml and 273.31 µg/ml respectively as opposed to that of the scavenging effects of ascorbic acid and BHT of 5.698 µg/ml and 8.816 µg/ml respectively. The highest reducing power was showed by ethanol extract followed…
