【摘要】：目的:研究畲药白山毛桃根的质量标准,为制定合理的质控方法提供科学依据。方法:通过对畲药白山毛桃根的水分、总灰分、浸出物、重金属及有害元素的测定、粉末显微鉴别、化学鉴别、活性成分总黄酮及总三萜含量测定等项目的研究,为白山毛桃根药材质量标准的提高积累了一定的实验数据。结果:白山毛桃根的化学反应、显微特征明显;活性成分总黄酮以芦丁为对照品在0.009 42~0.056 50 mg·m L-1浓度范围内线性关系良好(r=0.999 1),平均加样回收率为97.33%(RSD=1.98%);总三萜以熊果酸为对照品在0.004 89~0.017 12mg·m L-1浓度范围内线性关系良好(r=0.998 7),平均加样回收率为96.58%(RSD=1.79%)。结论:研究所得方法简便、准确、重复性好,可有效控制白山毛桃根的质量。
[Abstract]:Objective: to study the quality standard of Baishanmao Peach root and provide scientific basis for establishing reasonable quality control method. Methods: the determination of water, total ash, extract, heavy metal and harmful elements, powder microscopic identification, chemical identification, determination of total flavonoids and total triterpenoids in the roots of Peach were studied. Some experimental data were accumulated for the improvement of the quality standard of Baishanmao Peach root. Results: the chemical reaction and microscopic characteristics of Peach root were obvious. The linear range of Rutin was 0.009 mg mL ~ (-1) (r = 0.999 1), and the average recovery was 97.33% (RSD=1.98%). The calibration curve of ursolic acid was linear in the concentration range of 0.004 12mg / mL ~ (-1) for ursolic acid (r = 0.998 7), and the average recovery was 96.58% (RSD=1.79%). Conclusion: the method is simple, accurate, reproducible and can effectively control the quality of Peach root.
