Abstract Background Melanoma and breast cancers are two common cancers worldwide. Due to the side effects of chemotherapy drugs and the occurring resistance against them, the development of green drugs has been received more attention. Methods The anticancer effects of three essential oils from the Citrus family and their identified major constituents (limonene) were first investigated against melanoma and breast cancer cell lines (A-375 and MDA-MB-468). By preparing chitosan nanoparticles containing them, an attempt was then made to improve their effectiveness. Results Chitosan nanoparticles containing Citrus sinensis and Citrus limon essential oils with IC50s of 0.03 and 0.124 μg/mL on A-375 cells, and 23.65 and 40.32 μg/mL on MDA-MB-468 showed distinct anticancer efficacies. Conclusion The prepared formulations could thus be considered as green anticancer agents in complementary medicine and therapies.
