of Mattinata, a rare and ancient Mediterranean citrus fruit, was investigated by sequence analysis of the ribosomal internal transcribed spacer regions, which assigns it as a variety of L. Morphological, chemical, and biomolecular approaches, including light and electron microscopy, HPLC-ESI-MS/MS, and antioxidant and anti-inflammatory assays, were used to characterize the flavedo and albedo parts, usually rich in bioactive compounds. The morphological findings showed albedo and flavedo cellular structures as "reservoirs" of nutritional components. Both albedo and flavedo hydroalcoholic extracts were rich in polyphenols, but they were different in compounds and quantity. The flavedo is rich in acid and rutin, whereas the albedo contains high levels of hesperidin and quercitrin. Antioxidant, anti-inflammatory, and genoprotective effects for albedo and flavedo were found. The results confirmed the health properties of flavedo and highlighted that albedo is also a rich source of antioxidants. Moreover, this study valorizes of Mattinata's nutritional properties, cueing its crops' repopulation.
马蒂纳塔橘（Citrus medica L. var. ）是一种罕见的古老地中海柑橘类水果，对其核糖体内部转录间隔区（ITS）进行序列分析，将其鉴定为 L. 的一个品种。采用形态学、化学和生物分子学方法，包括光学和电子显微镜、HPLC-ESI-MS/MS 和抗氧化和抗炎测定，对通常富含生物活性化合物的橘白和橘红部分进行了表征。形态学研究结果表明，橘白和橘红的细胞结构是营养成分的“储存库”。橘白和橘红的水醇提取物均富含多酚，但在化合物和数量上有所不同。橘红富含柠檬酸和芦丁，而橘白则含有高水平的橙皮苷和槲皮苷。发现橘白和橘红具有抗氧化、抗炎和基因保护作用。研究结果证实了橘白的健康特性，并强调了橘白也是抗氧化剂的丰富来源。此外，本研究还强调了马蒂纳塔橘的营养价值，提示其作物的重新种植。
