This work characterises and distinguishes Italian and Asian goji berries, combining three analytical approaches to determine 5 light stable isotope ratios, 57 mineral elements and 14 carotenoids.

The study analyses stable isotope ratios and provides full HPLC-DAD-MS characterisation of the carotenoid fraction in goji berries for the first time. The isotopic composition of Italian berries was characterised by δ¹³C values ranging between −28.2‰ and −25.7‰, δ¹⁵N between 2.3 and 7.3‰, δ³⁴S between 2.6 and 7.9‰, and D/H between −112 and −49‰.

Italian goji berries were shown to have a particular composition and interesting nutritional characteristics, specifically a higher total carotenoid content (355 mg/100 g dw mean content vs 198 mg/100 g dw) and higher content of some micronutrients: K, B, Cu, Mo, Se, and Zn.

On the basis of δ³⁴S, Y, U, Cu, Rb, zeaxanthin palmitate and total carotenoid content, discriminant analysis correctly classified all samples according to their geographical origin.

这项工作表征和区分了意大利和亚洲枸杞，结合了三种分析方法，确定了5种光稳定同位素比，57种矿物质和14种类胡萝卜素。

该研究首次分析了稳定的同位素比率，并首次提供了枸杞中类胡萝卜素成分的完整HPLC-DAD-MS表征。意大利浆果的同位素组成的特点是δ ¹³ C值之间的范围内-28.2‰和-25.7‰，δ ¹⁵ Ñ2.3和7.3之间‰，δ ³⁴ 2.6和7.9‰之间S，和d / H -112之间- 49‰。

已显示意大利枸杞浆果具有特殊的成分和有趣的营养特征，特别是较高的总类胡萝卜素含量（355 mg / 100 g dw平均含量对198 mg / 100 g dw）和某些微量元素：K，B，Cu的含量较高，Mo，Se和Zn。

关于δ的基础³⁴ S，Y，U，铜，RB，玉米黄质棕榈酸酯和总的类胡萝卜素含量，判别分析根据其地理起源正确地分类的所有样本。
