“Natural products” refers to any substance produced by a living organism. Such compounds are well-known to exert beneficial effects on the matrix where they occur, i.e., natural products, foods, etc. Besides beneficial effects, organoleptic characteristic modifications and improved technological characteristics may also be included. In recent decades, an ever-increasing number of scientific papers have been published on the relationship between diet and the incidence of chronic diseases. It is necessary to correctly evaluate the effects that natural compounds that could exert on both the food matrix and the organism. The aim of this Entry Collection of Enclyclopdia is to collect a number of documents focused on the analysis, applications, and/or evaluation of activities of natural products in food and natural products. Papers focused on the mechanisms underlying the effects produced by the natural products will also be included.

Tautomerism of β-Diketones and β-Thioxoketones
The present overview concentrates on recent developments of tautomerism of β-diketones and β-thioxoketones, both in solution and in the solid state. In particular, the latter has been a matter of debate and unresolved problems. Measurements of 13C, 17O, and 2H chemical shifts have been used. Deuterium isotope effects on chemical shifts are proposed as a tool in the study of this problem. Photoconversion of β-diketones and β-thioxoketones are discussed in detail, and the incorporation of β-diketones into molecules with fluorescent properties is assessed. Finally, docking studies of β-diketones are scrutinized with an emphasis on correct tautomeric structures and knowledge about barriers to interconversion of tautomers.

Bioactive Compounds from Eruca sativa Seeds
Eruca sativa Miller (Brassicaceae) is an insect-pollinated diploid annual species which grows spontaneously in the entire Mediterranean basin from semi-arid to arid-hot conditions and is cultivated in Northern America, Europe, and Asia as either salad or oilseed crop. Here, some essential background was provided on this versatile crop, summarizing the present status of Eruca sativa research focusing on the wealth of bioactive ingredients in its seeds, which may find exploitation in agriculture, in the food industries and as nutraceuticals for their antioxidant and anti-inflammatory properties. Fatty acids of Eruca sativa seed oil, gums, glucosinolates and soluble and insoluble phenol and flavonoid fractions in the defatted press cake are the main bioactive compounds considered to date by the scientific literature and that deserve attention for their physical and biological activities.
