Sonchus asper profiling

The current investigation presents a two-fold approach to rediscovering the potential of Sonchus asper as a wild edible plant, both in its raw extract form and as a nano-formulated product. S. asper is commonly utilized as a food ingredient, and through HPLC-MS analysis of raw and cooked leaf extracts, 38 compounds and 6 essential amino acids were identified. The antioxidant activity and the hypoglycemic effect of non-edible leaves were demonstrated. The incorporation into liposomes maximized the health-promoting properties for potential pharmaceutical or food applications. Furthermore, the study aimed to promote the valorization of traditional dishes, and contribute to biodiversity conservation and sustainable use of S. asper, thus enhancing economic profits. In this regard, the commercialization of S. asper could: (i) contribute to improving the well-being of rural and urban communities, being S. asper a wild edible plant available at low cost, environmentally friendly, resilient, and adaptable; (ii) generate landowner economic returns.

本研究采用双轨策略，重新发掘苣荬菜（Sonchus asper）作为野生食用植物的应用潜力，涵盖其粗提物与纳米制剂两种形式。苣荬菜常被用作食品原料，本研究通过高效液相色谱-质谱联用（HPLC-MS）技术对其生叶与熟叶提取物开展分析，共鉴定出38种化合物与6种必需氨基酸。研究证实了苣荬菜非食用叶片的抗氧化活性与降血糖功效。将其活性成分包载入脂质体（liposomes）中，可最大化其健康促进功效，有望应用于医药或食品领域。此外，本研究旨在推动传统菜肴的食材增值利用，助力苣荬菜的生物多样性保护与可持续开发，进而提升经济效益。据此，苣荬菜的商业化应用可实现两大价值：其一，作为低成本、环境友好、抗逆性强且适应性广的野生食用植物，助力城乡社区民生福祉的改善；其二，为土地所有者带来经济收益。
