Functional foods: Traditional use and European legislation
The concept of functional foods was born in Japan in the 1980s. They are foods that were developed specifically to promote health or reduce the risk of disease. Functional foods have not already been defined by the legislation in Europe. Generally, they are considered as those foods which are intended to be consumed as part of the normal diet and which contain biologically active components which offer the potential of enhanced health or reduced risk of disease. Attention concerning this category of foods has grown, new products have appeared in the European market and interest has turned to define the standards and guidelines for the development and promotion of this kind of foods. In the European Union, there is harmonised legislation on health claims, while compounds, ingredients, plants are still regulated only at national level. The question of traditional use and the role of European Food Safety Authority as European Authority for Food Safety will be examined
A rare bis-rhamnopyranosyl-aromadendrin derivative and other flavonoids from the flowers of Genista cilentina Vals. an endemic species of Southern Italy
A rare bis-rhamnopyranoside of aromadendrin, besides isoflavones of chemosystematic importance and peculiar compounds never reported in the genus, was identified from the flowers of Genista cilentina, an Italian endemic species. The structure of the aromadendrin derivative was elucidated by means of 1D and 2D NMR techniques. The exclusivity of the observed molecular pattern in comparison with other Genista species was further discussed from a chemotaxonomic point of view. A huge quantity of flavonoids in aglycone form resulted selectively accumulated in flowers
Iridoid glucosides from Viburnum macrocephalum
The phytochemical study of the aerial parts of Viburnum macrocephalum Fortune, an ornamental species of Chinese origin, led to the isolation, together with the phenolic glucoside triandrin, of three iridoid glucosides: the novel 7-cinnamoylpatrinoside (1), and the known 7-p-coumaroylpatrinoside (2) and patrinoside (3)
