研究了叶类蔬菜（羽衣甘蓝）类胡萝卜素成分的品种差异、季节变化和耕作方法。尽管样本是从商业农场采集的，但采样是经过计划的，以便评估每个因素的影响。夏季品种Tronchuda的类胡萝卜素和维生素A值显着升高；冬季也有同样的趋势，但差异无统计学意义。 CV. 的 β-胡萝卜素、叶黄素-紫黄质和总类胡萝卜素水平以及维生素 A 值在冬季显着高于夏季。曼泰加羽衣甘蓝。另一方面，Tronchuda 品种的新黄质含量在夏季显着较高。与来自使用农用化学品的农场的样品相比，来自“天然”农场的样品中的所有类胡萝卜素成分均显着较高。
Cultivar differences, seasonal variations, and farming practices on the carotenoid composition of a leafy vegetable (kale) were studied. Although the samples were taken from commercial farms, sampling was planned so that the effect of each factor could be assessed. The carotenoids and the vitamin A value were significantly higher in the cultivar Tronchuda in the summer; the same tendency was observed in the winter, but the differences were not statistically significant. The beta-carotene, lutein-violaxanthin, and total carotenoid levels, as well as the vitamin A value, were significantly higher in the winter than in the summer for cv. Manteiga kale. On the other hand, the neoxanthin content was significantly higher in the summer for the Tronchuda cultivar. All the constituent carotenoids were significantly higher in the samples from the "natural" farm as compared to those from the farm that used agrochemicals.
