IN VITRO ANTIOXIDANT AND FREE RADICAL SCAVENGING POTENTIAL OF HOLOSTEMMA ADA – KODIEN K. SCHUM., AN IMPORTANT RARE MEDICINAL PLANT
AbstractThe present study was undertaken to evaluate the in vitro antioxidant activities of hexane, ethyl acetate and methanolic extracts of Holostemma ada kodien root tubers. The above extracts exhibited a dose dependent scavenging activity against DPPH radicals, Superoxide radicals, and Nitric oxide radicals. Further, the MeOH, EtOAC extracts showed relatively higher reducing power compare to that of BHT. TLC of the above extracts using the DPPH as a spraying reagent revealed yellow spots against purple background indicating the presence of potent antioxidant compounds
