摘要
目的比较不同采收期童子益母草中水苏碱和益母草碱的含量,为确定童子益母草的种植和采收时间提供依据。方法采用高效液相色谱法测定童子益母草中水苏碱和益母草碱含量,并考察不同产地、不同采收期童子益母草中两种生物碱的含量。结果两种不同种植基地童子益母草中水苏碱和益母草碱的含量随种植时间延长呈上升趋势,约5个月达平衡,而后有所下降。结论该方法分离度好,稳定,适合作为童子益母草的质量控制方法,可为童子益母草种植和采收提供依据。
Objective To compare the contents of stachydrine and leonurine of young Leonurus heterophyllus （YLH） in different harvest time for the further scientific guidance for implantation and harvest of YLH. Methods A high performance liquid chromatography （HPLC） method was established for the simuhaneous determination of stachydrine and leonurine in YLH. The contents of these two alkaloids in different places of production and harvest time were determined. Results The contents of the two alkaloids increased over time in both two places of production, reached a peak at about the 5th month after implantation, and then decreased. Conclusion The method is stable with good resolution, and suitable for the quality control of YLH. The data obtained can provide research base for the implantation and harvest of YLH.
