Courgette is considered as a low-calorie vegetable with health-promoting properties. However, scientific publications focused on the profile and content of bioactive compounds in courgette, as well as the potential fruit quality modulating factors, are rare. Due to the high adaptability of courgette to weather and agronomic conditions, it is produced on a global scale. The aim of this study was to analyse the impact of organic versus conventional agronomic practices on the concentration of selected antioxidants in courgette fruits. Fruits of two courgette varieties (Astra Polka and Nimba) produced in an organic and conventional system were tested by high performance liquid chromatography (HPLC) to determine the content of polyphenols (flavonoids and phenolic acids), carotenoids, chlorophylls, and vitamin C. Organic courgette fruits were characterised by their significantly higher content of phenolic acids and flavonoids when compared to the conventionally grown fruit. The organic cultivation might be a good method to increase concentration of bioactive compounds with antioxidant properties in courgette fruits. Nevertheless, the identified trends should be further confirmed, with attention paid to other courgette varieties, as well as to the potential interactions between the plant genotype, agronomic system and the location-specific growing conditions.
西葫芦被认为是一种具有促进健康特性的低热量蔬菜。然而，专注于西葫芦中生物活性化合物的概况和含量以及潜在果实品质调节因素的科学出版物却很少。由于西葫芦对天气和农艺条件具有高度适应性，因此在全球范围内都有种植。本研究的目的是分析有机与传统农艺实践对西葫芦果实中选定抗氧化剂浓度的影响。通过高效液相色谱法（HPLC）对在有机和传统系统中种植的两个西葫芦品种（阿斯特拉波尔卡和宁巴）的果实进行测试，以确定多酚（类黄酮和酚酸）、类胡萝卜素、叶绿素和维生素C的含量。与传统种植的果实相比，有机西葫芦果实的酚酸和类黄酮含量明显更高。有机栽培可能是提高西葫芦果实中具有抗氧化特性的生物活性化合物浓度的一种好方法。然而，所确定的趋势应进一步得到证实，同时要关注其他西葫芦品种，以及植物基因型、农艺系统和特定地点生长条件之间的潜在相互作用。
