摘 要:目的 用反相高效液相色谱(RP-HPLC)法同时测定五味子中五味子醇甲、五味子酯甲、五味子甲素及五味子乙素的含量,对不同产地五味子的木脂素类成分进行研究.方法 采用Venusil XBP C18色谱柱(4.6 mm×250 mm,5 μm),流动相为甲醇(A)-水(B),梯度洗脱(0~25 min,A 为72%;26~50 min,A 为77%),流速1 mL·min-1,柱温25 ℃,检测波长250 nm.结果 五味子醇甲、五味子酯甲、五味子甲素及五味子乙素分别在1.27~10.17 μg(r=0.999 6),0.27~2.13 μg(r=0.999 0),0.32~2.52 μg(r=0.999 5),0.89~7.19 μg(r=0.999 4)范围内呈良好的线性关系;平均回收率分别为100.51%,101.19%,102.05%,99.73%,RSD分别为2.09%,1.83%,1.99%,1.34%.结论 该方法准确、简便、分离好,无干扰,可为完善五味子质量评价提供依据.Objective To establish a method for determining schizandrin, schisantherin A, deoxyschizandrin and γ- schishandrin in Schisandra chinensis by RP-HPLC, and to study lignans composition of Schisandra chinensis from different origins. Methods A Venusil XBP Ci8 column(4.6 mmx250 nun, 5 tam) column was used with gradient elution by methanol (A)-water(B) (0-25 min, 72% A; 26-50min, 77% A) as the mobile phase. The flow rate was 1.0 mE · min-1. The column temperature was 25 ℃. The detection wavelength was set at 250 nm. Results The calibration curves of schizandrin, schisantherin A, deoxyschizandrin and γ-schishandrin were linear within the ranges of 1.27- 10. 17 tag (r = 0. 999 6 ) , 0.27- 2.13 μg( r= 0. 999 0), 0.32-2.52 μg( r= 0. 999 5), and 0.89-7.19 tag( r= 0. 999 4) , respectively,. The average recoveries were 100.51% (RSD of 2.09% ), 101.20% (RSD of 1.83% ), 102.05% (RSD of 1.99% ), 99.73% (RSD of 1.34% ), respectively. Conclusion The method is accurate, simple and selective, providing a basis for improvement of quality evaluation for Schisandra chinensis.
