Preface

From the down of human civilization man is in close contact of nature and is still trying to find out solutions of their problems from natural sources. The plants have been considered as the most natural of all the other natural things and, therefore, attracted the attention of scientific community. There was a time not too long ago when most compounds came from plants. But beginning about 50 years ago, chemistry took over the charge from botany and started synthesizing the compounds. Infact, with increasing population, maintenance of our current standard of living and improvement in our quality of life forced the society to depend on the products of chemical industry. The 20th century has been highly successful in this regards. However, with advent of 21st century, a wave of environmental awareness and consciousness is developed regarding the side effects of used and generated hazardous chemical substances. An increasing concern is realized for using renewable natural resources in a manner which does not diminish their usefulness for sustainable development of future generations. Today, chemists, botanists, microbiologists, environmentalists, engineers and medicos have joined their hands for greening the chemistry and working for the search of remedies from natural resources.

The research all over the world on known and unknown plants has resulted in good amount of natural magic bullets. These researches have created interest and awareness among the people and they are changing their taste. The picture of advertisements noticed these days demonstrates the unmistakable trends of popularity of natural green products. Phytochemicals are classified as prim
