In vitro anticancer and antioxidant potential of Cestrum species

The methanolic extract of leaves and stem of Cestrum nocturnum and Cestrum diurnum were investigated for their antioxidant and anticancer attribute through standard methods. 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was carried out to estimate the antioxidant activity of the extracts. Whereas, anticancer potential of extracts were tested against colon cancer cell line, HCT 116 and acute myeloid leukemia (AML) cell lines, THP-1. Results showed that extracts of both plants exhibited a very strong antioxidant activity in a dose dependent manner. In addition, both extracts efficiently increased the cell death in two different cancer cell lines. Moreover, DNA fragmentation analysis further strengthens the anticancer potential of extracts of both types of plants. Current study, therefore, provide a preliminary data highlighting the antioxidant and anticancer activities of methanolic extract of leaves and stem of Cestrum nocturnum and Cestrum diurnum.
