Background d‐Limonene, a monoterpene from citrus fruit has been found to have chemopreventive and chemotherapeutic activities in various types of cancers. In this study, we evaluated the in vivo effect of d‐Limonene on a K562‐induced model of chronic myeloid leukemia (CML) in C57BL/6 mice. Method The tail vein injection model of K562 cells in immunocompromised C57BL/6 mice was developed and evaluated for characteristics of the disease. The mice were treated with d‐Limonene and evaluated for haematological parameters. We also evaluated the effect of d‐Limonene on angiogenesis using the chick chorioallantoic membrane (CAM) assay. Results In a complete blood count, a significant dose‐dependent reduction in white blood cell, neutrophil and lymphocyte counts, but an elevation in red blood cell count and haemoglobin content was observed with d‐Limonene treatment compared to the disease control or untreated group. In the CAM assay, d‐Limonene produced a significant dose‐dependent reduction in number of blood vessels in treatment groups compared to the vehicle‐treated group. Conclusion These studies suggest promising anti‐leukemic and anti‐angiogenic effects of d‐Limonene in the treatment of CML.
