摘要
运用微波技术提取红景天总黄酮 ,用比色法测定黄酮含量。测得红景天中黄酮含量 2 0 .87% ,平均回收率为1 0 1 .2 % ,RSD =1 .6 3 % (n =5 )。结果显示 ,与常规法比较 ,微波法提取速度更快 。
The extraction and content determination chromoco of Rhodiola kirilowii Rgl.ex Maxim by different ways was applied in chromoco of Rhodiola kirilowii Rgl.ex Maxim.Content determination was used by colorimetry.The chromoco content of Rhodiola kirilowii Rgl.ex Maxim.is 20.87%,and 17.53%.Microwave technique way is faster,and extracting rate is higher.
