摘要:
目的：分析不同采样期党参炔苷的含量。方法：炔苷含量采用高效液相色谱分析，TC-C18色谱柱(4.6 mm×250 mm，5 μm)，以乙腈-水(22∶78)为流动相,流 速：1.0 mL/min。检测波长267 nm，柱温25℃。结果：党参炔苷在1.12～0.80 μg/mL范围内呈良好的线性关系，r=0.999 6，精密度RSD为1.28%(n=6)，重复性RSD为1.9%，平均回收率为99.50%，RSD为1.90%(n=6)，测定了不同采收期党参中党参炔苷的含量范围为0.87～3.00 mg/g。结论：分析了不同采样期党参炔苷的含量，为党参规范化栽培提供参考。
Abstract:
Objective: To analyze the contents of lobetyolin in DangShen［Codonopsis pilosula(Franch.)Nannf.］ at different sampling periods. Methods: The contents of lobetyolin were analyzed by HPLC, TC-C18 chromatographic column (4.6 mm×250 mm, 5 μm), acetonitrile-water (22:78) were as the mobile phase, flow rate: 1.0mL/min. Detection wavelength was 267 nm, the temperature: 25℃. Results: Lobetyolin showed better linear relationship in the range between 1.12 to 0.80 μg/mL, r=0.999 6, accuracy RSD was 1.28%(n=6), repetition RSD was 1.9%, average recovery rate was 99.50%, RSD was 1.90% (n=9), the contents of lobetyolin ranged from 0.87 to 3.00mg/g at different sampling periods.Conclusion:The contents of lobetyolin are analyzed in different sampling periods in order to provide reference for standardized cultivation of DangShen.
