摘要： Water lilies, members of the Nymphaeaceae family, are globally cultivated aquatic plants known for their diverse colors and significant ornamental, economic, beverage, medicinal, and ecological value. In this study, we employed ultra-high performance liquid chromatographytandem mass spectrometry (UPLC-MS/MS) to analyze the non-volatile components and simultaneous distillation extraction (SDE) in combination with two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOFMS) to analyze the volatile components in five water lily species and varieties. Results showed that 118 differential metabolites including flavonoids, phenolic acids, amino acids, and lipids were screened among 533 non-volatiles. Cyanidin-type anthocyanins, including cyanidin-3-O-galactoside, cyanidin-3-O-glucoside, and cyanidin-3rutinoside, are present in high amounts in the purple-colored Nymphaea 'Detective Erika'. Conversely, delphinidin is found in significant quantities in Nymphaea 'Blue Bird', which exhibits a blue color. KEGG analysis showed that flavonoid biosynthesis and anthocyanin biosynthesis exhibited significant enrichment. Additionally, a total of 166 volatiles were screened in water lilies, mainly including aromatic compounds, alkynes, ketones, alcohols and esters. Among them, the concentrations of key compounds including 1,11-dodecadiene, benzyl alcohol, benzaldehyde, α-farnesene and dimethyl sulfide, varied significantly among different samples. This study reveals significant variations in chemical compounds among different Nymphaea species and varieties. These findings contribute to enhancing our comprehension of the metabolic variability and composition of water lilies, which might shed light on unlocking new possibilities for their potential application in the beverage industry. © The Author(s).
