Abstract:Rosehip is fleshy pseudocarp developed from receptacles of faded roses，which has health function and medicinal value. Three rosehip cultivars named Rosa rugosa Thunb. Jilin，R. rugosa Zizhi，and R. centifolia Xiangshui were measured for basic nutritional components，mineral elements，amino acid composition，sugars，organic acids，dietary fiber，and active substances. A principal component analysis （PCA） was conducted to comprehensively evaluate the three cultivars. The results showed that rosehip could be a good source of nutrition，characterized by low fat （0.19-0.69 g/100 g），high protein （1.28-3.14 g/100 g），comprehensive amino acid composition，and high content of potassium （405.00-486.00 mg/100 g），calcium （79.40-260.00 mg/100 g），and dietary fiber（5-12 g/100 g）. Its sugars are mainly composed of fructose and glucose. It has high content of organic acids，mainly citric acid，with a sugar-to-acid ratio of 3-4. It is also rich in folic acid，α-tocopherol，β-carotene，riboflavin，ascorbic acid，and other active substances that are highly beneficial to human body. The PCA results indicated that the indicators contributing most to the principal components were primarily lysine，valine，fructose，riboflavin，iron，vitamin E，arginine，and total dietary fiber. The comprehensive nutritional quality scores of the three rosehip cultivars were in descending order of R. centifolia Xiangshui，R. rugosa Zizhi，and R. rugosa Thunb. Jilin.
