| 摘要 | Invasive plants often pose challenges to ecosystem management, yet they can also serve as valuable resources when integrated with traditional knowledge. This study explores the sustainable applications of the invasive species Galinsoga quadriradiata through an innovative combination of ethnobotanical and chemical analyses. Ethnobotanical investigations revealed its utility as both a food source and animal feed, particularly for poultry. Nutritional profiling highlighted its exceptional nutrient density, including high levels of protein (17.70 ± 0.24 g/100 g dry weight), fiber (45.10 ± 0.10 g/100 g), potassium (2.17 ± < 0.01 g/100 g), and calcium (1.73 ± < 0.01 g/100 g), supporting its traditional uses. Furthermore, bioactive compounds such as flavonoids (0.46 ± < 0.01 g/100 g) and proanthocyanidins (0.146 g/100 g) underscore their potential health benefits. Metabolomic analysis via HS–SPME–GC–MS identified 238 volatile constituents, predominantly aldehydes (16.66%), alcohols (16.31%),a nd sesquiterpenes (13.01%), with 5,10-dioxatricyclo[ 7.1.0.04,64,64,6]decane (5.39%), 1-hexanol (3.54%), and 2-hexenal (3.26%) as the most abundant components. These volatiles provide mechanistic insights into the plant’s attractiveness as food and feed while also suggesting ecological interactions. Our findings highlight G. quadriradiata as a promising candidate for sustainable feed and food production. By bridging ethnobotanical practices with scientific validation, this study establishes a robust framework for repurposing invasive species (G. quadriradiata) into valuable resources, promoting agricultural resilience, ecological sustainability, and biodiversity conservation. |
