**Abstract**

Cancer is one of the most dreadful disease conditions all over the world. With the side effects and cost of conventional treatment, there is a demand for new therapies to prevent cancer. Research studies proved many plant products possess anticancer properties. Currently, a few plant-based drugs are used to treat it. The phytochemicals are investigated by in vitro and in vivo to assess their mechanism of action against cancer. This chapter is an overview of anticancer compounds extracted from plants of Solanaceae family with the potentials results. Many research has confirmed the anticancer efficiency of the biomolecules, such as solanine, solamargine, tomatidine, Withanolides, scopoletin, capsaicin found in Solanaceae, and their mode of action, such as cell cycle arrest, inhibiting signaling pathways, autophagy, suppression of enzymes in various human cancer cell lines of breast, pancreas, colorectal, liver, and cervical and also in animal models. This chapter seeks to provide an outline of key examples of anticancer activity of phytochemicals from the Solanaceae family, which offers a track for the development of novel medicines for cancer treatment as a single drug or in combinational drug. This chapter helps to identify the novel bioactive molecule for cancer treatment as lead molecule with less side effects in future.
