Frontiers in Natural Product Chemistry is a book series devoted to important advances in natural product chemistry. The series features volumes that cover all aspects of research in the chemistry and biochemistry of naturally occurring compounds, including research on natural substances derived from plants, microbes and animals. Reviews of structure elucidation, biological activity, organic and experimental synthesis of natural products as well as developments of new methods are also included in the series.Volume 12 of the series brings together the following discussions:-Importance of organoleptic evaluation as a cornerstone of virgin olive oil quality assessment.-The chemical diversity and biological activities of the marine fungi Asperlligus-Melatonin biosynthesis, circadian regulation, and its presence in foods of plant and animal origin.-The complex chemistry of tea in relation to processing methods and health outcomes.-A critical analysis of the chemistry, mechanisms and the structure-activity relationships of flavonnes, aiming to establish them as promising antiviral agents
