Simultaneous Determination of Soybean Isoflavones and Icariin in Soybean-Eucommia-Epimedium Granules by HPLC
摘要
Abstract
To establish a method for the simultaneous determination of soy isoflavones(daidzin,genistin,daidzein and genistein)and icariin in Soybean-Eucommia-Epimedium Granules.In this study,high-performance liquid chromatography was employed.A Shimadzu Shim-pack GWS C1 8 reversed-phase column(5 μm,4.6 mm × 250 mm)was used.Gradient elution was performed with acetonitrile(A)and phos-phoric acid aqueous solution(pH=3,B)as the mobile phase.The injection volume was 10 μL,the column temperature was maintained at 30℃,and the detection wavelength was set at 260 nm.The results indicated that daidzin,genistin,daidzein,genistein,and icariin showed good linear relationships between their contents and peak areas within the ranges of 7.94~63.52 μg/mL,9.28~74.24 μg/mL,4.84~38.72 μg/mL,2.22~17.72 μg/mL,and 2.516~314.5 μg/mL,respectively.The correlation coefficients(R2)were 0.999 9,0.999 9,0.999 2,0.999 1,and 0.999 9,respectively.In the precision test,the relative standard deviations(RSDs)of the five components were 0.362%,0.358 8%,1.251 5%,0.220 3%,and 0.357 7%,respectively.The stability test demonstrated that all components in the sample solution remained stable within 24 h,with RSDs of 0.665 2%,1.835 6%,1.423 9%,0.762 6%,and 0.555 8%,respectively.The average recoveries were 101.70%,100.66%,102.67%,99.40%and 102.29%,respectively.The average contents of daidzin,genistin,daidzein,genistein,and icariin in three batches of products determined by this method were(39.79±0.75)mg/100 g,(32.52±0.37)mg/100 g,(20.04±0.337 8)mg/100 g,(9.48±0.15)mg/100 g,and(371.18±2.16)mg/100 g(n=9),respectively.The established method is accurate,simple,and reliable,and can be applied for the con-tent determination of Soybean-Eucommia-Epimedium Granules.关键词
