INTRODUCTION
Spectroscopy is the measurement and interpretation of Electromagnetic radiation (EMR) absorbed or emitted when the molecules or atoms or ions of a sample move from one energy state to another energy state. This change may be ground state to exited state or vice-versa. EMR is made up of discrete particles called photons. EMR has got both wave characteristic as well as particle characteristics. This means that it can travel in vacuum also.

INTRODUCTION
Dioscorea is a slender twining annual herbs distributed throughout the tropical and subtropical region of the world. Dioscorea is a fascinating plant with many uses in the history of the development of modern pharmacy. The number of species is quite overwhelming (over 600) and the Ethno-botanical uses are most interesting. Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae. They are tuberous herbaceous perennial climber, growing to 2–12 m or more tall. The leaves are spirally arranged, mostly broad heart-shaped. The flowers are individually inconspicuous, greenish-yellow, with six petals; they are mostly dioecious, with separate male and female plants, though a few species are monoecious, with male and female flowers on the same plant. The fruit is a capsule in most species, a soft berry in a few species. Several species, known as yams, are important agricultural crops in tropical regions, grown for their large tubers. Some species produces large cylindrical tubers penetrating deep into the ground, while other varieties produce small or large tubers close to the soil surface. Sometimes 1-2 tubers are produce at the base of the plant while in the other cases cluster of tubers are observed. Many of these are toxic when fresh, but can be detoxified and eaten, and are particularly important in parts of Africa, and Asia.

INTRODUCTION
Nature always stands as a golden mark to exemplify the outstanding phenomenon of symbiosis. The biotic & abiotic elements of nature are all interdependent. The plants are indispensable to man for his life. The knowledge of drug has accumulated over  thousands of years as a result of man’s inquisitive nature so that today we posses many effective means of ensuring health care.
In the part, almost all the medicines used were from the plants, the plant being men’s only chemist for ages. The history of medical plants dates back to RIG VEDA, perhaps the oldest repository of human knowledge, which was written in about 4500-1600 B.C. then there is the Ayurveda which given us detail accounts of many herbal drugs.
