摘要: |
目的 建立曼陀罗子中东莨菪碱的含量测定方法。方法 色谱柱为Kromasil C18(250 mm×4.6 mm,5 mm)。乙腈-水(含0.07 mol·L-1磷酸钠和0.017 5 mol·L-1十二烷基硫酸钠,0.5%磷酸,0.1%三乙胺)(37∶63)为流动相,检测波长为216 nm。结果 东莨菪碱在0.038 1~0.190 5 mg·mL-1内呈良好的线性,r=0.999 9;平均回收率为97.0%,RSD为0.93%。结论 该方法简便、灵敏、准确、重复性好,可作为曼陀罗子的质量控制标准。 |

Abstract: |
OBJECTIVE To establish the method of determination of scopolamine in Datura stramonium. METHODS Kromasil C18(250 mm×4.6 mm, 5 mm) column was employed. Mobile phase was the mixture of acetonitrile and Na3PO4 buffer (contains 0.07 mol·L-1 Na3PO4, 0.017 5 mol·L-1 SDS, 0.5% H3PO4, 0.1% trithylamine)(37∶63). RESULTS A good linearity of scopolamine was achieved in the range of 0.038 1-0.190 5 mg·mL-1(r=0.999 9). The average recovery of scopolamine was 96.97% and RSD was 0.93%. CONCLUSION This method is simple, sensitive, accurate with good reproducibility, and can be used for the quality control of Datura stramonium. |
