目的:建立女贞子中甘露醇的含量测定方法。方法:采用比色法测定。结果:用本法测定甘露醇在(12.5~75.0)μg范围内线性关系良好,相关系数r为0.9994;其平均回收率为97.06%,RSD为0.662%。结论:采用该法对女贞子中甘露醇含量进行测定精密度和重复性良好,更具有普遍性及简便性。
Objective: To establish a method for the determination of mannitol in Ligustrum lucidum. Method: Colorimetric assay. RESULTS: The linearity of mannitol in the range of (12.5-75.0) μg was determined by this method. The correlation coefficient r was 0.9994. The average recovery was 97.06% and the RSD was 0.662%. Conclusion: This method has good precision and repeatability in measuring mannitol content in Ligustrum lucidum, and it is more universal and simple.
