The plants are indispensable to man for his life. Nature’s beauty in terms of health care is appreciated by developing various systems of traditional system (Ethnomedicine). Ethnomedicine may be defined broadly as the use of plants by human as medicine, but this use could be called ethnobotanic medicine. There is growing focus on the importance of medicinal plants in the traditional health care system (viz. Ayurveda, Unani, Homeopathy, Yoga) in solving health care problems. Because of this awareness plant materials and herbal remedies derived from them represent substantial portion of the global market . The demand for herbal products is growing exponentially through out the world and major pharmaceutical companies are currently conducting expensive research on plant materials for their potential medicinal value. India is one of 12th leading biodiversity centre in the world and also one of the oldest, richest and most diverse cultural living traditions associated with the use of medicinal plants. Currently, natural products pass through a phase of reduced interest in drug discovery because of the enormous efforts which are necessary to isolate the active principles and to elucidate their structures.
