Abstract：To identify high-quality wild vegetable resources suitable for cultivation in Taizhou region,this study systemati-cally evaluated the nutritional and safety characteristics of both native and introduced wild vegetable species.Under stan-dardized cultivation conditions(without chemical fertilizers or pesticides,with minimal organic fertilizer application),eight native Taizhou wild vegetables and eight introduced species were sampled and analyzed for their nutritional and an-ti-nutritional components.The results demonstrated that all 16 wild vegetable species exhibited abundant nutritional con-tent,including vitamin C content(6.80-1 066.00 μg·g-1),total flavonoids content(0.25-36.10 mg·g-1),carotenoids content(10.60-222.40 μg·g-1),and mineral elements,while maintaining nitrate nitrogen content(7.96-409.63 μg·g-1),oxalic acid content(8.10-3 205.20 μg·g-1),and heavy metal elements(Pb,Cd)below food safety thresholds.However,organic fertiliz-er application may lead to arsenic accumulation in some species(0.05-2.80 μg·g-1).The native species Toona sinensis,Ka-limeris indica,and Medicago polymorpha demonstrated optimal nutritional profiles,suggesting strong potential for agri-cultural development.In contrast,Chenopodium album,Tetragonia tetragonioides,and Mesembryanthemum cordifolium exhibited significant nitrate accumulation,warranting careful cultivation management.Additionally,Gynura divaricata and Eruca sativa showed tendencies for heavy metal bioaccumulation,necessitating rigorous safety monitoring in produc-tion systems.This study provides a scientific basis for the development and utilization of wild vegetable resources in the Taizhou region.
