Our research was aimed at assessing the effect of accumulation of carotenoids, polyphenols, vitamin C and ripening stage in the rosehip fruits of two species—Rosa canina, Rosa rugosa and two cultivar—Rosa rugosa ‘Rubra’ and Rosa rugosa ‘Alba’. The amounts of carotenoids, polyphenols and vitamin C were determined using the high-performance liquid chromatography (HPLC) method. The obtained results showed that the significantly highest amount (107.15 mg 100 g⁻¹) of total carotenoid was determined in the fruits of Rosa canina at ripening Stage V. While results indicated that significant amount of total polyphenols were established at Stages I and II in the Rosa Rugosa ‘Alba’ and Rosa rugosa ‘Rubra’ cultivars (110.34 mg 100 g⁻¹, 107.88 mg 100 g⁻¹ and 103.20 mg 100 g⁻¹ 103.39 mg 100 g⁻¹). At ripening Stage I, in the fruits of Rosa rugosa the greatest increases were established in the contents of vitamin C (3036.08 mg 100 g⁻¹).

成熟阶段对玫瑰果品种/品种中类胡萝卜素、多酚和维生素 C 积累的影响

我们的研究旨在评估两种玫瑰果果实中类胡萝卜素、多酚、维生素 C 和成熟阶段的影响 - Rosa canina、Rosa rugosa和两个栽培品种 - Rosa rugosa 'Rubra' 和Rosa rugosa 'Alba'。使用高效液相色谱 (HPLC) 方法测定类胡萝卜素、多酚和维生素 C 的含量。获得的结果表明，在成熟阶段 V 的犬蔷薇果实中测得的总类胡萝卜素含量最高（107.15 mg 100 g ^-1）。而结果表明，在阶段 I 和 II 中建立了大量的总多酚在玫瑰'Alba'和Rosa rugosa'Rubra'栽培品种（110.34 mg 100 g ^-1、107.88 mg 100 g ^-1和103.20 mg 100 g ^-1 103.39 mg 100 g ^-1）。在成熟阶段 I，蔷薇果实中维生素 C 的含量增加最大（3036.08 mg 100 g ^-1）。
