RESUMO

The study is aimed to explore the metabolism rule of Lonicera japonica by investigating the primary and secondary metabolism process in different growth periods. HPLC and other methods were used to measure metabolism indexes of leaves collected in last ten days of every month. The results suggested that the maximum (78.59%) and minimum (60.83%) of water content were found in March and December. The content of total sugar reached a high level from December to February and the maximum (275.8 mg•g⁻¹) appeared in October, while it reduced significantly at other time. The change of chlorogenic acid, neochlorogenic acid, galuteolin, caffeic acid were basically consistent and the highest content of them synchronously appeared (42.79, 2.01, 7.13, 0.16 mg•g⁻¹) in March. The content of primary and secondary metabolite in L. japonica leaves reached a high level from March to May, and the main related elements with effective components were K, Mg, P, aspartate, threonine, proline, valine, cysteine, isoleucine and phenylalanine.
