Cancer is the uncontrolled development of abnormal cells in the body. It is considered as the leading public health problem in both developed and the developing countries. As no drug of cancer is establish to be completely efficient and safe as anticancer therapy and is responsible for the prolonged toxicity and also causes various side effects. Chemoprevention of cancer by natural products is beneficial, as these compounds have the nominal side effects and short of toxicity compared to the synthetic compounds. The phenomena of Carcinogenesis is very complex and includes so many signaling pathways. Thus Phytochemicals are measured as the right candidates for developing the anticancer drug. The study for developing more potent candidates which can obstruct or slow down the expansion of the cancer cells without c au s in g any side effects from these phytochemicals are still in progress and Many new phytochemicals and its derived analogs have been recognized as potential candidates for anticancer therapy among these one of the potent plant is Stevia rebaudiana. The leaves of Stevia rebaudiana tends to possess zero calories, and consists mainly of ent kaurene diterpene glycosides generally recognized as steviol glycosides. Stevioside is the main sweet component found in S. rebaudiana. studies suggest that the stevioside along with v other associated compounds including rebaudioside A, steviol, and isosteviol tends to have therapeutic benefits including anticancer activity. Taking in consideration the above mentioned factors we have investigated the Anticancer potential of extracts of S. rebaudiana. Four extracts was prepared using petroleum ether, chloroform, ethyl acetate and aqueous methanol. T47D cell line have been used to evaluate the anticancer potential using MTT assay. AD-2 that is chloroform extract showing IC50 value of 7.79μg/ml. Moreover IC50 value of AD-4 that is aqueous methanol was also comparatively better and found to be 9.53 μg/ml and AD-1 that is petroleum ether had shown IC50 value of 9.58μg/ml. Thus, various extracts have shown good Antiproliferative activity and S. rebaudiana can be further investigated for its anticancer potential. Furthermore docking study on estrogen receptor–alpha, androgen receptor and aromatase receptor discovered that the phytochemicals of the plant have good binding affinity towards all the three mentioned receptors and can be suitably customized to search its anticancer potential. Moreover unfavorable ADME profile can be overcome by structure modification. Thus on the basis of in-vitro and in-silico data we can conclude that S. rebaudiana extracts have promising anticancer potential. further isolation of compounds have been done successfully and total four compounds have been isolated. two compounds ASP-2 and ASP-4 have been successfully characterized and found to be Stevioside and Rebaudioside A respectively which are already known compounds.
