目的:研究金莲花及其茎叶中总黄酮含量。方法:以芦丁为对照品,采用分光光度法测定金莲花及其茎叶中总黄酮的含量。结果:坝上地区盛花期的金莲花总黄酮含量普遍较高,御道口牧场最高8.459%,三道河口最低5.139%,平均值为6.939%,最大值与最小值相差3.32%;2006年和2007年机械林场金莲花的总黄酮含量仅相差0.43%;金莲花茎叶的总黄酮含量最大值为6.511%,在6月中旬达到峰值。结论:坝上不同产区的金莲花总黄酮含量较高且相差不大,质量稳定;金莲花的茎叶部分可以作为金莲花的新药源;围场县广字基地金莲花茎叶的最佳采收时间为6月中旬。 相似文献

金莲花Trollius chinensis Bge.为毛茛科多年生草本植物,以花入药,其所含的黄酮类化合物具有清热解毒、抗菌消炎等功效[1-2],具备良好的应用价值和开发前景.牡荆苷作为黄酮类化合物的有效成分之一,除具有抑菌作用外,还有抗癌、降压、抗炎及解痉作用[3-4].作者分别对金莲花的主要资源分布区坝上及周边地区、不同种源的金莲花中牡荆苷含量进行了对比研究,为金莲花的质量评价、品种对比选育以及适宜种植区的选择提供了有价值的参考. 相似文献

Objective To study the total flavonoid content in flowers,stems and leaves of Trollius chinensis Bge. in BaShang at different picked times. METHODS Using rutin as a reference substance,the total flavonoid in flowers,stems and leaves at different picked times were determined by UV absorption . RESULTS The maximum content of flowers in BaShang was 8.459%,the minimum content was 5.139%,while there is a 3.32% discrepancy between them, and the average was 6.939%;The content discrepancy of the total flavonoid content in flowers(2006 and 2007) was only 0.43%;The maximum content of stems and leaves was 6.511%,which appeared in the the middle ten-day of June. CONCLUSION The total flavonoid content in flowers of BaShang is high and has a steady quality .The stems and leaves can be used as a new officinal part.The best picked time in Weichang is the middle ten-day of June. 相似文献
