The fruits of the dog rose Rosa canina contain phenolic acids, proanthocyanidins, tannins, flavonoids, fatty acids, pectins, carotenoids and fruit acids (ascorbic acid, malic acid and citric acid) (Ashtiyani, S.C. et al, 2013).
The amount of ascorbic acid in Rosa canina has been studied (Ercisli, S., 2007). In addition to vitamin C, the following other nutrients in Rosa canina have been reported: Carotenoids, tocopherol, bioflavonoids, tannins, pectin, sugars, organic acids, amino acids, essential oils, phosphorus, potassium, calcium, magnesium, iron, copper, manganese and zinc (Ercisli, S., 2007).
According to Horvath et al., the following 6 major carotenoids have been identified in Rosa canina: epimers of neochrom, lutein, zeaxanthin, rubixanthin, lycopene and β-carotene (Horvath, G., et. al. 2012).
The anti-inflammatory and anti-oxidative effects of hip-bone powder are well described. However, the specific active ingredients that are responsible for the positive effect on joint health are examined. No component has been identified as the active substance. It is rather a combination of some of the many active ingredients found in rose hip that are responsible for the beneficial effects of hip powder.
Therefore, the rosehip used for SUKO Rosehip Powder is carefully selected and cultivated under optimal climate conditions in southern Chile to optimize the content of active ingredients.
