Unripe tomatoes are among the main waste produced during tomato cultivation and processing. In this study, unripe tomatoes from seven different Italian cultivars have been investigated to evaluate their nutraceutical potential. Phytochemical investigation allowed shedding light on the identification of seventy-five bioactive compounds. The highest amount of polyphenolic and glycoalkaloids along with the high level of antioxidant activities was found in the Datterini tomatoes variety. The peculiarity of this variety is the high chlorogenic acid content, being ten times higher compared to the other cultivars examined. Moreover, the total α-tomatine amount has been found substantially higher (34.699 ± 1.101 mg/g dry weight) with respect to the other tomato varieties analyzed. Furthermore, the cultivars metabolomic profiles were investigated with the PCA approach. Based on Datterini cultivar's metabolomic profile, its waste-recovery could represent a good option for further added value products in pharmaceutical and nutraceutical areas with a high α-tomatine content.
未成熟的番茄是番茄种植和加工过程中产生的主要废弃物之一。在这项研究中，研究了来自意大利的七个不同品种的未成熟番茄，以评估其营养潜力。植物化学研究揭示了 75 种生物活性化合物的鉴定。在 Datterini 番茄品种中发现了最高量的多酚和糖苷生物碱以及高水平的抗氧化活性。该品种的特点是绿原酸含量很高，是其他检测品种的十倍。此外，总α-茄碱的含量（34.699 ± 1.101 mg/g 干重）与其他分析的番茄品种相比也显著更高。此外，还采用 PCA 方法研究了品种的代谢组学图谱。基于 Datterini 品种的代谢组学图谱，其废物回收可能是制药和营养保健品领域具有高α-茄碱含量的附加值产品的一个很好的选择。
