Fruits of Lycium barbarum L. have been used in Chinese traditional medicine for centuries. In the last decade, there has been much interest in the potential health benefits of many biologically constituents of these fruits. The high level of carotenoids offers protection against development of cardiovascular diseases, diabetes and related comorbidities.

In the present work two different selections of Lycium barbarum L., cultivated in Italy and coming from three discrete harvest stages, were subjected to two different grinding procedure and to a simplified extraction method of carotenoid component. CIELAB colorimetric analysis of the freshly prepared purees and HPLC-DAD analysis of carotenoid extracts were performed and compared. Different harvesting dates and grinding procedures deeply influence the carotenoids content and statistical analysis showed high correlation between carotenoid content and colorimetric data.

The final model provides a reliable tool to directly assess carotenoid content by performing cheap and routinely colorimetric analyses for food industry.

枸杞的果实已经在中药中使用了几个世纪了。在过去的十年中，人们对这些水果的许多生物学成分对健康的潜在益处产生了浓厚的兴趣。高水平的类胡萝卜素可预防心血管疾病，糖尿病和相关合并症的发展。

在目前的工作中，来自意大利的三个不同收获阶段的枸杞的两个不同选择经过了两种不同的研磨程序和简化的类胡萝卜素成分提取方法。并比较了新鲜制备的果泥的CIELAB比色分析和类胡萝卜素提取物的HPLC-DAD分析。不同的收获日期和研磨步骤对类胡萝卜素含量有深远的影响，统计分析表明类胡萝卜素含量与比色数据之间具有高度相关性。

最终模型提供了一种可靠的工具，可以通过对食品行业进行廉价且常规的比色分析来直接评估类胡萝卜素的含量。
