| Summary: | The edible flower buds of Hemerocallis citrina Baroni are used both as a vegetable and functional food. It has various health benefits due to the diversity of natural products. However, the establishment of functional components in the edible flower bud remains to be studied. We conducted a high-resolution metabolomic analysis of flower buds at three developmental stages, 1–2 cm, 4–6 cm, and edible (10–15 cm). Our analysis revealed 157 differential accumulated metabolites, including flavonoids (49), fatty acids (17) and terpenoids (13) while most of them decreased during flower bud development. Among them, 2 flavonoids, 2 long-chain fatty acids and 1 triterpene saponin are highly accumulated in edible flower buds. Furthermore, the expression levels of catalytic genes mirrored the changes in metabolite levels detected. These results track the dynamics of functional component accumulation during edible flower bud development, laying the theoretical basis for nutrition formation in H. citrina. |
