The hydro-alcoholic extract of Opuntia elatior fruits was studied for its in-vitro antioxidant and cytotoxic activity by using DPPH radical scavenging and MTT assay on K-562 cell line (Human chronic myelocytic leukemia). The total phenolic, flavonoid, flavonone and betanin pigment content were also estimated by spectrophotometric methods. It showed the significant antioxidant activity with IC50 value 88.16µg/ml and potent cytotoxic action against K-562 cell line with IC50 value of 25 µM/ml compared with the standard.
