Plant secondary metabolites have been a fertile area of chemicalinvestigation for many years, driving the development of bothanalytical chemistry and of new synthetic reactions andmethodologies. The subject is multi-disciplinary with chemists,biochemists and plant scientists all contributing to our currentunderstanding. In recent years there has been an upsurge ininterest from other disciplines, related to the realisation thatsecondary metabolites are dietary components that may have aconsiderable impact on human health, and to the development of genetechnology that permits modulation of the contents of desirable andundesirable components.
Plant Secondary Metabolites: Occurrence, Structure and Rolein the Human Diet addresses this wider interest by covering themain groups of natural products from a chemical and biosyntheticperspective with illustrations of how genetic engineering can beapplied to manipulate levels of secondary metabolites of economicvalue as well as those of potential importance in diet and health.These descriptive chapters are augmented by chapters showing wherethese products are found in the diet, how they are metabolised andreviewing the evidence for their beneficial bioactivity.
