摘要： 用分光光度法分别测定了锦鸡儿属植物小叶锦鸡儿、南口锦鸡儿、树锦鸡儿、青海锦鸡儿、扁刺锦鸡儿、鬼箭锦鸡儿不同部位的总黄酮含量，发现总黄酮含量最高的部位为花（接近3%）和复叶（2%~3%），其次是茎的皮部（约1%），根中各部位的总黄酮含量较低（不足1%）。对叶、花等部位类黄酮等化学成分的研究有助于锦鸡儿属植物资源的可持续利用和生态环境的保护。

Abstract: Total flavonoids content of samples from different organs of Caragana microphylla Lam, C.zahlbruckneri C K Schneid, C arborescens(Amm) Lam, C chinghaiensis Liou, C boisi Schneid, C jubata (Pall) Pior were determined with the method of spectrophotometry. The results showed that organs with the highest content of total flavonoids are flower(nearly 3%) and compound leaf(2%-3% ), followed by the cortex of the stem(about 1%). Content of total flavonoids in root is relatively low(less than 1%). Study and developing of constituents including flavonoids in the organs of flower and leaf will be helpful to sustainable usage of Caragana Fabr and protection of ecologicalenvironment.

Key words: Caragana Fabr, Total flavonoid, Rutin
