Phytochemicals are nonnutritive compounds in plants that have health-protective benefits. A diet rich in plant foods, including certain fruits, vegetables, whole grains, nuts, and legumes, will provide various phytochemicals, including phenolic compounds, terpenoids, carotenoids, and other antioxidants. The intake of phytochemicals has been associated with protection from and/or treatment of cardiovascular disease, certain cancers, diabetes, and hypertension, among many other diseases and conditions. As such, research efforts on the profiling of phytochemicals and on the understand of their mechanisms of action and health benefits are highly important.

This Methods Collection will focus on the methods used to study phytochemicals, including but not limited to the screening, extraction, isolation, quantification, and characterization of phytochemicals from various sources, as well as the investigation on the bioavailability, metabolism, pharmacokinetics, molecular mechanism, and functionality of phytochemicals utilizing in vitro or in vivo models.
