基于色彩色差计的川楝子炮制前后含量和颜色变化

目的:建立了川楝子药材中川楝素含量的高效液相方法,采用在线式非接触红外控温炒药机炒制川楝子,比较川楝子炒焦前后川楝素的含量变化及药材颜色变化.方法:采用色彩色差计测量炒焦前后药材颜色变化；采用色谱柱为Wondasil C18柱,甲醇-水(1:1)为流动相,检测波长为217 nm,测定川楝素.结果:川楝素平均回收率为10...

Comparison of Contents and Color Changes in Fructus Toosendan before and after being Processed

Objective: In this study,authors created a process to measure the contents of Toosendanin,an effective component in Fructus Toosendan,using HPLC.Use of on-line non-contact infrared temperature drug machine to stir-frying Fructus Toosendan,compare the toosendanin in Fructus Toosendan content and color changes before and after stir-frying.Methods:It was carried out on a Wondasil C18 column with a mobilephase methanol-water(11),and a detection wavelength of 210nm for Toosendan.Results:The averaged recovery of Toosendanin reached 100.6%,RSD=1.57%(n=6);average contents decreased 37.69%(RSD= 2.19%)of 10 batches Fructus Toosendan after stir-frying,Fructus Toosendan total color value of processed products 41.97(RSD= 0.28%).Conclusion:Precision and reprod uction of the method is preferable.The method is simple,convenient,reliability and can be as a kind of method to determine the contents for Fructus Toosendan;Use of on-line non-contact infrared temperature drug machine to stir-frying 10 batches Fructus Toosendan,it has a higher stability of contents and color changes in Fructus Toosendan before and after being Processed.
