摘要

目的: 建立头花蓼及热淋清颗粒中没食子酸的含量测定方法。方法: 采用反相高效液相色谱法

DiamonsilTM (钻石) C18柱(4.6 mm×250 mm

5 μm)

流动相甲醇-水-N

N-二甲基甲酰胺-冰醋酸(1∶95∶3∶1)

流速1.0 mL·min- 1

检测波长272 nm

柱温25 ℃。结果: 没食子酸在0.139 6~1.396 0 μg线性良好(r=0.999 97)。头花蓼平均回收率99.35%

RSD为2.61%

热淋清颗粒平均回收率97.86%

RSD为0.73%。结论: 该法重复性好

专属性强

可用于控制头花蓼药材及其单方制剂热淋清颗粒的质量。为头花蓼药材规模化种植提供科学依据。

Abstract

Objective: To establish an HPLC method for determination of the contents of gallic acid in Polygonum capitatum and Relinqing granules. Method: The reserved HPLC method was achieved. Diamonsil C18 colunm (4.6 mm×250 mm

5 μm) with MeOH-H2O-DMF-HAc (1∶95∶3∶1) as amobile phase at flow rate of 1.0 mL·min- 1and detection wavelength was at 272 nm and the column temperature was at 25 ℃. Result: The calibration curve was linear in the range of 0.139 6-1.396 0 μg (r=0. 999 97). The average recovery rate of gallic acid in P. capitatum was 99.35% (RSD 2.61%)

and was 99.35% (RSD 0.73%) in Relinqing granules. Conclusion: The method is reliable

specific and with good repeatability.It can be used for the quality control of P.capitatum and Relinqing granules and provide a science bases for the planting of polygonum cap itatum.
