摘要
采用紫外分光光度法测定缬草(Valeriana officinalis)中总缬草素的含量。结果表明,缬草素在5～25μg/mL范围内,其浓度与吸光度呈良好线性关系(r=0.999 8),该方法回收率为98.94%～101.07%,准确、快速、重复性好,可用于缬草中总缬草素含量的测定。
The total valepotriates in Valeriana officinalis was determined by spectrophotometry.The results revealed a good linear relationship within the range of 5～25 μg/mL（r=0.999 8）.The recovery rate was 98.94%～101.07%.This method was accurate,rapid and reproducible for measuring the total valepotriates in Valeriana officinalis.
