目的 研究不同采收期对野罂粟全草中野罂粟碱含量的影响 ,为开发提供依据。方法 高效液相色谱法。色谱柱为 Shim- Pack CL C- ODS(4.6 mm× 2 5 0 mm) ,流动相为甲醇 -水 -二乙胺 (5 5 0∶ 45 0∶ 0 .45 ) ,波长 2 6 1nm,外标法。结果 不同采收期野罂粟中野罂粟碱含量差异较明显 ,其中 7,8月份含量较高。结论 每年 7,8月份采收野罂粟全草最适宜。

Object To study the content of nudicauline in Papaver nudicaule L. from different harvest period, so as to provide the basis for development of the plant. Methods The nudicauline content in P . nudicaule was determined by HPLC with Shim-Pack CLC-ODS (4. 6 mm× 250 mm) , mobile phase was methano l-water-diethy lamine (550∶ 450∶ 0. 45) , detection wav elength was at 261 nm. ResultsThe contents of nudicauline in P . nudicaule were greatly different from different harvest period, the content of nudicauline is higher in both July and Augest. Conclusion The whole plant is best harvested during July and Augest.
