Abstract: In order to provide the reference of rationalization utilized Humulus Scandens.(Lour.) Merr., this paper was engaged in the study on the trend of nutrient components and flavonoids content of Humulus scandens. (lour.) merr in different months. This paper studied the dynamic pattern of nutrient components (amino acids) and utilized the orthogonal design to measure the flavonoids content of Humulus Scandens. (Lour.) Merr at different stages from July to October. The results showed that compared with different stages, significant difference existed in CP content in July and September (P＜0.01) and no significant difference in August and October; and significant difference existed in ASH and Ca content in October(P＜0.01); significant difference existed in EE and CF content in August(P＜0.05).With the growth stages progressing, CP content increased, the maximum in September and next in October;ASH and Ca varied with the trend of high-low-low-high, EE content maximized in September and next in July;CF content maximized in August and next in September;TAA and TAA/CP increased with the growth stages progressing, TEAA/NEAA varied with the trend of high-low-high-low; the total flavonoids content increased from July to September,and the lowest in October.Given the trend of nutrient components and total flavonoids content,it’s advisable that the nutrient components of Humulus scandens.(lour.) merr was higher in September and October, and the total flavonoids content was higher in August and September,and the humulus scandens. was utilized in September.
