Rosaceae, a rose family, includes numerous genera of shrubs both those wild-growing and those cultivated. The Wild Rose species (Rosa canina) is a raw material, which constitutes a source of many valuable substances. Compared to the synthetic vitamin C, the natural vitamin C contained in wild rosa hips is better absorbed by human body and 3 to 5 times more active than the synthetic one. One of the most valuable rose varieties is the Polish ‘Konstancin’ agricultural rose variety that is characterized by a high content of vitamin C and very high fecundity. Both the rose hips and the rose flower petals are valuable raw materials used in the food processing industry. Conserves made from rose show a high nutritional and pro-health value verified by many researches and attributed to the occurrence of biologically active components therein that act synergistically in human organisms.
