Rose hips are particularly high in vitamin C, one of the richest plant sources available. However, RP-HPLC assays of fresh rose hips and several commercially available products revealed a wide range of L-ascorbic acid (vitamin C) content, ranging from 0.03 to 1.3%.
Rose hips have been used as a source of vitamin C.
Rose hips contain the carotenoids beta-carotene, lutein, zeaxanthin and lycopene, which are under basic research for a variety of potential biological roles, such as inhibiting oxidation of low density lipoprotein.
