摘要： 试验旨在研究不同月份葎草的营养成分及总黄酮含量的变化，为葎草合理、适时利用提供参考。在郑州牧业工程高等专科学校实训基地采收7—10月份的野生葎草，测定葎草在不同月份的营养成分含量，同时用正交试验法测定葎草总黄酮的含量，比较各月份总黄酮含量变化。结果表明，7、9月份的葎草中粗蛋白质（CP）含量与各个月份的含量差异极显著（ P<0.01），8与10月份的含量差异不显著；10月份的葎草中粗灰分（ASH）、Ca含量与各个月份的含量差异极显著（ P<0.01），其他各月份葎草的ASH含量差异不显著，7、9月份的葎草中Ca含量差异不显著；8月份的葎草中粗脂肪（EE）含量与各个月份的含量差异显著（P<0.05），而其他各月份的含量差异不显著；8、9月份的葎草中粗纤维素（CF）含量与各个月份含量差异显著（P<0.05），7与10月份的含量差异不显著；其中CP含量随生长月份推进呈上升趋势，以9月份最高，10月份次之；粗灰分和Ca含量呈“高—低—低—高”的变化趋势，EE含量以9月份最高，7月份次之，CF含量以8月份最高，9月份次之；葎草总氨基酸（TTA）含量和TAA/CP均随生长月份推进呈上升趋势，以9月份最高，10月份次之，总必需氨基酸/非必需氨基酸（TEAA/NEAA）呈“高—低—高—低”的变化趋势；葎草总黄酮的含量从7—9月份呈上升趋势，10月份含量最低。因此，葎草在9、10月份的营养成分含量较高，而总黄酮含量在8、9月份含量较高，建议9月份刈割利用最好。

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.
