Current needs in the food and pharmaceutical natural products require more careful study and knowledge of the biochemical composition of non agricultural plant species, respectively briar fruits for cultivating them for alimental use. Rosa canina L. (Rosaceae) is a shrub of the spontaneous flora recognized for its nutritional and therapeutic properties because of the content of vitamin C, carotenoids, vitamins E, K, PP, D, B1, B2, sugars, pectins, malic acid, citric acid, α and β tocopherol (vitamin E) and carotenoids. In terms of the food, rosehip fruits can be used singly or in combination with other fruits (apple, sea buckthorn, tomato, etc) prepared in the soups, pasta, cakes, jam or marmalade, wine, juice or consumed as tea. Currently rosehip extracts are used in traditional medicine as a diuretic, laxative, for arthritis, gout, colds, vitamin C deficience, etc. Rosehip fruits can be sold as organic products derived from spontaneous flora, which do not apply to synthetic or treatments or products from organic plantations. Although in Romania and other countries, sweet briar grows in abundance in wild flora, few know the importance of this species. This species has a key position in the strategy of sustainable culture can offer solutions to problems the social, economic and environmental. As with all other countries rosehip is cultivated from a long time, in Romania recently began to setting up experimental plantations. Natural biodiversity of this species is very high, even in small habitat. The aim of the study is to identify and retrieve some valuable genotypes from tecnological and biochemical point of view, from the spontaneous flora from South-West, Romania. For the study were collected from rose hip fruits of local populations of Rosa canina, derived from the existing biodiversity in this area, on surfaces not worked for a period of over 10 years. Within those populations were studied the variability of technological parameters: length fruit, fruit diameter, weight and ratio L/D and biochemical content: TSS, vitamin C and acidity titrabila. The results were analyzed statistically, using LSD and comparison method (t-Test). The obtained values indicate the existence of populations of Rosa canina of a valuable content in the TSS, which is between 11% (P3) and 21% (P12), especially vitamin C content, over 600 mg/100g populations P1, P7, P12 and P19. The acidity in the study population was 1.5 to 2 %. This material could be used for the selection of plants with superior features, intended to be placed in programs of breeding in order to create varieties that meet the demands of the modern world.
