【摘要】 目的:测定金不换药材中延胡索乙素的含量。方法:采用双波长薄层扫描法(λS=280nm,λR=360nm)。结果:延胡索乙素在0.50μg-5.50μg间,点样量与峰面积呈良好线性关系,r=0.9994,回收率为100.33％,RSD=2.46％(n=3)。结论:该法精确、简便、重现性好。更多还原

【Abstract】 Objective:To establish a method for the determination of tetrahydropalmatine in stephania sinsica diels.Method:Dual wavelength TLC-scanning(λS=280nm, λR=360nm)was used.Result:The linear range of tetradroplmatine is 0.50μg-5.50μg,and the correlation coefficient is 0.9994.The recovery is 100.33%,and RSD is 2.46%. Conclusion:This method is accurate,simple and reliable.更多还原
