BACKGROUND:Tomatoes (Solanum lycopersicum) are important fruits in the Mediterranean diet and are considered to reduce the risk of different human diseases due to their antioxidative powers. OBJECTIVE:The purpose of the present study was to investigate the biodiversity within a set of 50 tomato fruit accessions collected across Turkey concerning their antioxidant capacities and the levels of potential health-beneficial compounds including phenolic compounds, carotenoids, ascorbic acid and tocopherols. METHODS:All accessions were simultaneously grown in an open experimental field in 2017 and ripe fruits were harvested for analysis. Antioxidant capacities of both hydrophilic and lipophilic extracts were determined using spectrophotometric assays after which individual antioxidants were identified by HPLC using an on-line antioxidant detection system. Phenolic acids, flavonoids, carotenoids and vitamins C and E were quantified using HPLC. RESULTS:The results indicated that there is a wide diversity within this small collection with respect to their hydrophilic and lipophilic antioxidants. CONCLUSION:Hydrophilic antioxidant capacity of the tomatoes was generally related to chlorogenic acid and Vitamin C levels, while lipophilic antioxidants were correlated to all-trans lycopene.

土耳其番茄中与健康相关的植物化学物质的自然多样性

背景：番茄（Solanum lycopersicum）是地中海饮食中的重要水果，由于其抗氧化能力，被认为可降低人类疾病的风险。目的：本研究的目的是调查整个土耳其收集的一组50个番茄果实的生物多样性，这些番茄的抗氧化能力和潜在有益健康的化合物（包括酚类化合物，类胡萝卜素，抗坏血酸和生育酚）的水平。方法：所有种质均在2017年的开放实验田中同时种植，并收获成熟果实进行分析。使用分光光度法测定亲水性和亲脂性提取物的抗氧化能力，然后使用在线抗氧化剂检测系统通过HPLC鉴定单个抗氧化剂。酚酸，类黄酮，类胡萝卜素和维生素C和E使用HPLC进行定量。结果：结果表明，该小系列产品在其亲水性和亲脂性抗氧化剂方面具有广泛的多样性。结论：番茄的亲水抗氧化能力通常与绿原酸和维生素C水平有关，而亲脂抗氧化剂与全反番茄红素有关。
