摘　　要： 研究了葎草中总黄酮和木犀草素含量的季节变化规律。分别采用分光光度法和高效液相色谱法测定了重庆地区不同月份葎草中总黄酮与木犀草素的含量,结果表明:不同月份葎草总黄酮与木犀草素含量差异较大,且两指标成分含量的季节变化趋势基本一致,总黄酮与木犀草素的含量分别为14.74～23.83 mg·g^(-1)和0.25～1.11 mg·g^(-1),其中10月份总黄酮与木犀草素的含量均最高。 Seasonal variation of total flavonoids and luteolin in Humulus scandens were investigated. The content of total flavonoids was determined by ultraviolet spectrophotometric method. The content of luteolin was measured by RP-HPLC. The contents of total flavonoids and luteolin in H. scandens in different months were significantly different. The trend of seasonal variation of total flavonoids and luteolin were similar. The content range of total flavonoids varied froia 14. 74 mg· g-1 to 23.83 mg · g-1. The contents of luteolin ranged from 0.25 mg· g-1 to 1.11 mg ·g-1. The contents of total flavonoids and luteolin in the sample harvested in Octover were higher than others.
