Cancer is a group of diseases characterized by uncontrolled division of cells in the part of the body and is able to invade to other tissues or parts of the body through blood and lymph system. Cancer is of different types that based on the organ or type of cell in which they start. Different cancer types like cancer of lung, esophagus, stomach, oral, pharynx, colon and skin, are affecting the human population. In the developed world, cancer is the leading cause of death whereas in the developing world it is the second leading cause of death as evidenced by the projected number of new cases and death worldwide.1 About 12.7 million people were suffering from cancer and 7.6 million people died of cancer in 2008 worldwide. Of the above estimate 56% of the cancer cases and 64% of the deaths were reported in the developing countries. Cancer burden in India is lower than that of developed countries like United States,2 and WHO, projected the dramatic rise in cancer burden to 20 million by 2020 with 70% in the developing countries.3 The cause for higher cancer burden in developing countries is due to population growth and ageing that would have massive impact on the number of new cancer cases and deaths. In India, the more prevalent cancers in men are lung, esophagus, stomach, oral and pharynx, while in women, breast and cervix cancers followed by stomach and esophagus. Recently it has been reported that there were more than 5 lakhs people died of cancer in India in the year 2010, and in female most deaths were due to breast cancer. The present study aimed to investigate the plants Celosia cristata and Gomphrena globosa, for anticancer property by invitro method and select the best plant with potent antitumor property and investigate the plant in detail. The objectives of the study were as follows: _ Authentication of the selected plant, _ Successive extraction of the plant material using non-polar to polar solvents, _ Screening of the plant extracts for anticancer property by in-vitro, _ Selection of the plant extract with potential anticancer property, _ Toxicity study on the selected plant extract, _ Screening of the selected plant extract for anticancer property by in-vivo, _ Phytochemical screening of the selected plant extract, _ Isolation and structural elucidation of the active constituent(s) from the Extract, _ Screening of the active constituent(s) for anticancer property by in-vitro and in-vivo, _ Studying the mechanism of anticancer activity of the active constituent. In conclusion, the results of the study demonstrated that the plant, Gomphrena globosa posses anticancer activity and the compound responsible for this activity was found to be Oleuropein.
