This book arose from our lectures on Artificial Intelligence at the Uttaranchal Institute of Technology, Dehradun and later at the Dehradun Institute of Technology, Dehradun. We started writing a new text out of dissatisfaction with the literature available at the time. Most books on Artificial Intelligence seemed to be chaotic collections of models and there was no clear unifying theoretical thread connecting them. The results of my efforts are published in this book. We tried in this book to put the accent on a systematic development of Artificial Intelligence theory and to stimulate the intuition of the reader by making use of many figures. Intuitive understanding fosters a more immediate grasp of the objects one studies, which stresses the concrete meaning of their relations. Since then some new books have appeared, which are more systematic and comprehensive than those previously available, but We think that there is still much room for improvement. The book has been written for undergraduates, and the only mathematical tools needed are those which are learned during the years at Institute.

Anthocyanins are a large group of the bioflavonoids family from the class phenolics. Phenolics are the coloured compounds present in nature in flowers, fruits, leaves etc. These colours play very crucial role in biodiversity. Flowers and fruits, are sole source of rich antioxidant. These antioxidant have potentials to cure various diseases like cancer. Therefore in present book authors tried to compile the various anthocyanins from different plants that possess anthocyanins and their role in curing various human ailments. Its high time to target such molecules and isolate these anthocaynins as a rich source of therapeutic agents.Authors convey deep thanks to our great, young and dynamic Directors Shri Arpit Agarwal and Shri Amit Agarwal ji for unconditional support, family feelings, and everlasting encouragement. Authors feel immense pleasure to give thanks from bottom of our heart to our Academic Director Prof. C. K. Ojha for become a guiding force for all such research work. Authors are also grateful to Department of Science and Technology, Jaipur for financial support under the auspices of Centre with Potential for Excellence in Biotechnology.

Mira realized quickly, though, the road to being a model mommy is not that smooth, her baby seems to think sleep is overrated, her boss has decided to show her the door, her pregnancy fat is staying steadfastly on, and having threatened to beat up the one woman who could get her son into the coveted playschool teddy footprints, plans for her first born are already going awry.
