Melon (Cucumis melo L.) is a significant source of substances able to provide human health benefits. From the 18th century in the Salento area (Apulia region), the cultivation of melon varieties (C. melo L.) has always been intense. Over the years, the production of this fruit has involved a large number of selected and preserved varieties in the different local districts. Unfortunately, most of the characteristics of locally grown vegetable varieties do not match the food industry requirements. Moreover, the agricultural land abandon leads these varieties to quickly disappear, thus affecting the intraspecific biodiversity. In order to characterize the inter-variety diversity of sweet melon (C. melo L. ssp. melo group inodorus) and the potential differences in the nutritional quality of fruits, a first investigation on the juice of five sweet melon varieties (locally known as "allungato", "scurzune", "egiziano", "minna de monaca", "pinto"), cultivated exclusively in the Salento area, was performed by H-NMR spectroscopy and Multivariate Analysis (MVA). The analysis grouped the samples into clusters according to the different variety. Interestingly, a different sugar (mono and disaccharides) content was observed among the grouped varieties, being sweetness the main characteristic of sweet melon quality and taste. A relative higher accumulation of monosaccharides (α-d and β-d glucose and α/β-d fructose) was found, in particular for the "minna de monaca" with respect to "allungato", "egiziano" and "pinto" varieties. Moreover, a marked high content of polyphenols and aromatic aminoacids as phenylalanine and tyrosine characterize the "allungato", "minna de monaca" and "pinto" varieties. An NMR-based metabolomic approach was used for the first time to describe these local landraces. This method may integrate other actions in order to achieving a reduction in the current rate of erosion of the biodiversity of Apulian horticultural species.
甜瓜(Cucumis melo L.)是提供人类健康益处的物质的重要来源。从 18 世纪开始,在萨伦托地区(普利亚大区),甜瓜品种(C. melo L.)的种植一直很密集。多年来,这种水果的生产涉及到不同当地地区大量选择和保存的品种。不幸的是,大多数当地种植的蔬菜品种的特性不符合食品工业的要求。此外,农业用地的废弃导致这些品种迅速消失,从而影响了种内生物多样性。为了描述甜瓜果(C. melo L. ssp. melo inodorus 组)的品种间多样性和果实营养质量的潜在差异,首次对五种甜瓜果(当地称为“allungato”、“scurzune”、“egiziano”、“minna de monaca”、“pinto”)的果汁进行了 H-NMR 光谱和多元分析(MVA)。分析根据不同的品种将样品分为不同的聚类。有趣的是,在分组品种中观察到不同的糖(单糖和二糖)含量,甜味是甜瓜果品质和口感的主要特征。发现单糖(α-d 和 β-d 葡萄糖和 α/β-d 果糖)的积累相对较高,特别是“minna de monaca”与“allungato”、“egiziano”和“pinto”品种相比。此外,“allungato”、“minna de monaca”和“pinto”品种的特征是含有大量的多酚和芳香族氨基酸,如苯丙氨酸和酪氨酸。首次使用基于 NMR 的代谢组学方法来描述这些当地的地方品种。这种方法可以结合其他行动,以实现减少普利亚园艺物种生物多样性的当前侵蚀速度。
