Abstract

Background: The globe artichoke (Cynara cardunculus var. scolymus L.) is extensively cultivated in the Mediterranean region, with Italy being a leading producer. Industrial processing of artichoke plants generates substantial amounts of residual materials, which are discarded annually. This accumulation of biowaste presents environmental challenges. However, these by-products remain rich in phytochemicals, such as dietary fibers, phenolic acids, sesquiterpene lactones, flavonoids, vitamins and minerals, similar to those found in the edible parts of the plant. The present study aimed to evaluate the potential of artichoke by-products by analyzing aqueous extracts (AEs) from seven cultivars, comprising two commercial hybrids and five local varieties, focusing on their phenolic content, antioxidant activity, and prebiotic potential.

Results: The primary phenolic compounds identified in the AEs were hydroxycinnamates, notably 5-O-caffeoylquinic acid and 3,5-di-O-caffeoylquinic acid, and flavonoids, primarily apigenin-7-O-rutinoside, luteolin and luteolin-7-O-rutinoside. These bioactive compounds were more abundant in two of the five local varieties, with concentrations exceeding those in commercial hybrids by more than twofold. Local varieties consistently exhibited higher total phenolic content and greater antioxidant activity, as determined by the DPPH (i.e. 2,2-diphenyl-1-picrilyhydrazil) assay. Furthermore, local varieties demonstrated a remarkable prebiotic potential, supporting more robust probiotic cell growth and resulting in greater acidification compared to commercial hybrids.

Conclusion: The findings highlight the potential for valorizing artichoke biowastes as dietary supplements. The rich functional and bioactive properties of these by-products, particularly in local varieties, offer promising applications in food-related industries. This approach not only leverages their nutritional benefits, but also addresses environmental concerns by valorizing biowaste. © 2025 The Author(s).

不同洋蓟品种副产品的酚类特征和营养保健品评估

背景：地中海地区广泛种植朝鲜蓟（Cynara cardunculus var.朝鲜蓟植物的工业加工产生了大量残留物，每年都会被丢弃。这种生物垃圾的积累给环境带来了挑战。然而，这些副产品仍然富含植物化学物质，如膳食纤维、酚酸、倍半萜内酯、类黄酮、维生素和矿物质，与植物可食用部分中的含量相似。本研究旨在通过分析七个栽培品种（包括两个商业杂交品种和五个本地品种）的水提取物（AEs）来评估朝鲜蓟副产品的潜力，重点研究其酚含量、抗氧化活性和益生元潜力：在 AE 中发现的主要酚类化合物是羟基肉桂酸，特别是 5-O-咖啡酰奎宁酸和 3,5- 二-O-咖啡酰奎宁酸，以及黄酮类化合物，主要是芹菜素-7-O-芸香糖苷、木犀草素和木犀草素-7-O-芸香糖苷。这些生物活性化合物在五个本地品种中的两个品种中含量更高，比商业杂交品种高出两倍多。根据 DPPH（即 2,2-二苯基-1-苦基肼）测定法，本地品种始终表现出更高的总酚含量和更强的抗氧化活性。此外，与商业杂交品种相比，本地品种表现出显著的益生菌潜力，支持更强大的益生菌细胞生长，并产生更大的酸化作用：结论：研究结果凸显了将朝鲜蓟生物废料作为膳食补充剂的潜力。这些副产品（尤其是本地品种）具有丰富的功能和生物活性特性，有望应用于食品相关行业。这种方法不仅能利用其营养价值，还能通过生物废料的价值化解决环境问题。© 2025 The Author(s).食品与农业科学杂志》由约翰威利父子有限公司代表化学工业学会出版。
