The book deals with novel applications of plant derived natural agents and their derivatives in the food, textile dyeing, medicinal, and environmental areas. Plant based natural products and their derivatives have strong influence on our everyday lives. They are needed for many everyday applications ranging from food, medicine, agriculture, textiles, and healthcare. This new book presents significant research advances about the use of plant-based natural products, mainly dyes and pigments, bioactive compounds and other plant extracts in the textile coloration, food, medicine, bioremediation and environmental applications. The topics of the ten informative chapters in Plant-Based Natural Products include the following: potential resurgence of natural dyes in applied fields; natural colorants from indigoid rich plants; phytochemical and pharmacological aspects of Butea monosperma plant; irradiation as novel pretreatment methods to improve wash fastness properties of plant derived natural dyes; dyeing studies with colorants extracted from the Lawsonia inermis plant; effect of drumstick leaf powder incorporation on quality of khakhra; physico-chemical properties of pineapple pomace powder and its incorporation in buffalo meat products; synthesis of curcumin complexes for medicinal and other industrial uses and phyto-remediation of toxic arsenic from wastewaters. Audience This book is a useful reference for academics, engineers and post-graduate students working in the fields of dyes and pigments, medicinal chemistry, bioremediation and environmental sciences, textiles, and materials science.
