Cancer is one of the most common devastating disease affecting millions of people per year. Cancer has been estimated as the second leading cause of death in humans. So there has been an intense search on various biological sources to develop a novel anti-cancer drug to combat this disease. Plants have proved to be an important natural source of anti-cancer therapy for several years. The plant-derived compounds have been an important source of several clinically useful anti-cancer agents. Plants have played an important role as a source of effective anti-cancer agents, and it is significant that over 60% of currently used anti-cancer agents are derived in one way or another from natural sources, including plants, marine organisms and micro-organisms. The marine floras are rich in medicinally potent chemicals predominantly belonging to polyphenols and sulphated polysaccharides. The chemicals have displayed an array of pharmacological properties especially antioxidant, immune stimulatory, and anti-tumor activities. This paper deals with the Modern technologies have opened vast areas of research for the extraction of biomedical compounds from tropical herbals, marine and coastal associated medicinal plants for anticancer properties which could be further designed to produce novel cancer drugs.
