以苗圃中生长的、盛花期时的淫羊藿属(Epimedium)植物叶片为材料,利用高效液相色谱仪测定不同物种叶片中4种药效黄酮苷的含量,同时测量叶片面积、叶片长宽比等参数。统计分析的结果表明,淫羊藿属不同物种的叶片形态与黄酮苷的含量之间存在一定的联系:活性成分含量高的淫羊藿,其叶片面积较小,形状多呈卵形,叶片革质化程度也较低。
Air-dried leaves of Epimedium in the nursery were collected at the full-bloom stage, and then investigated the contents of four different pharmacological flavonoids by high-performance liquid chromatography. Leaf area, leaf length, and leaf width were measured before processing materials. The results show that there is significant correlation between the leaf morphology of Epimedium species and the contents of flavonoids:leaves with high flavonoid content, are usually oval or long oval shape and less leathery.
