ABSTRACT The quality attributes of two goji berry cultivars, Lasa and New Big, grown in an organic system in the Lithuanian climate were investigated in two consecutive years (2015 and 2016). Concentrations of mineral elements (N, K, P, Mg, Ca, Fe, Zn, B, Cu, Mn, and Se), toxigenic elements (Pb and Cd), dry matter, soluble solids, vitamin C and carotenoids were evaluated. The results showed that the main mineral element in the goji berries was N, with values between 219.4 and 284.8 g kg−1. The New Big berries accumulated significantly higher concentrations of N, K, Fe, Zn, Cu and vitamin C compared with the Lasa berries. Significant differences were found between the two years in the concentrations of macro-elements, such as N, K and P, toxigenic elements (Pb and Cd), and carotenoids (lutein, zeaxanthin and β-cryptoxanthin). Concentrations of toxigenic elements were low and below the permissible limit levels. It was concluded that the goji berries tested in this study were a rich source of essential elements, such as N, K, Fe, Zn, B, Mn, and Cu, vitamin C and carotenoids, especially zeaxanthin and β-cryptoxanthin.

在立陶宛种植的有机枸杞 (Lycium barbarum L.) 中矿物质、可溶性固体、维生素 C、类胡萝卜素和产毒元素的浓度

摘要 连续两年（2015 年和 2016 年）对立陶宛气候下有机系统中生长的两个枸杞品种 Lasa 和 New Big 的质量属性进行了调查。对矿物元素（N、K、P、Mg、Ca、Fe、Zn、B、Cu、Mn 和 Se）、产毒元素（Pb 和 Cd）、干物质、可溶性固体、维生素 C 和类胡萝卜素的浓度进行了评估。结果表明，枸杞中的主要矿物元素是N，含量在219.4~284.8 g kg−1之间。与拉萨浆果相比，新大浆果积累了显着更高浓度的 N、K、Fe、Zn、Cu 和维生素 C。两年间，N、K 和 P 等大量元素、产毒元素（Pb 和 Cd）和类胡萝卜素（叶黄素、玉米黄质和 β-隐黄质）的浓度存在显着差异。产毒元素的浓度很低，低于允许的限度水平。得出的结论是，本研究中测试的枸杞富含必需元素，如 N、K、Fe、Zn、B、Mn 和 Cu、维生素 C 和类胡萝卜素，尤其是玉米黄质和 β-隐黄质。
