Rosehip (pseudo-fruit) of dog rose ( L.) is highly valued, and owing to nutritional and sensory properties it has a significant place in the food industry. This work represents an innovative report focusing on the evaluation of the phytochemical composition of rosehips (hypanthium and seed) grown in different locations in Serbia, using Raman microspectroscopy combined with multivariate data analysis. Some significant differences arose between the analysed rosehip samples with regard to the chemical profile of both hypanthium parenchyma cells and seed, although no evident discrimination was recorded between the samples of wild and cultivated rosehip. The differences between the hypanthium samples compared were mainly determined by the content of carotenoids, phenolic compounds and polysaccharides, whereas phenolics, polysaccharides (pectin, cellulose and hemicellulose) and lipids (to a lower extent) contributed to the seed sample discrimination. The differences observed between the rosehip samples may be attributed to abiotic factors (growing, ripening and storage conditions), which had a significant impact on the carotenoid and polyphenols biosynthesis.
犬蔷薇（Rosa canina L.）的玫瑰果（假果）具有很高的价值，因其营养和感官特性，在食品工业中占有重要地位。这项工作是一份创新性报告，重点是利用拉曼光谱结合多变量数据分析，评估在塞尔维亚不同地点种植的玫瑰果（花托和种子）的植物化学成分。在所分析的玫瑰果样品中，花托薄壁细胞和种子的化学特征存在一些显著差异，尽管野生和栽培玫瑰果样品之间没有明显的区分。所比较的花托样品之间的差异主要由类胡萝卜素、酚类化合物和多糖的含量决定，而酚类、多糖（果胶、纤维素和半纤维素）和脂质（程度较低）则导致了种子样品的区分。玫瑰果样品之间观察到的差异可能归因于非生物因素（生长、成熟和储存条件），这些因素对类胡萝卜素和多酚的生物合成有显著影响。
