摘  要:
[目的]建立白蔹药材中没食子酸的RP-HPLC含量测定方法,为白蔹药材的质量标准研究提供依据。[方法]采用Dikma Diamonsil C18(250×4.6 mm,5μm)色谱柱,以乙腈-0.2%磷酸(3∶97)为流动相进行等度洗脱。流速为1.0 ml/min,柱温为30℃,检测波长为270 nm。[结果]没食子酸检测浓度在3.15~202μg/ml的范围内与峰面积积分值呈良好的线性关系(R2=0.999 9);平均回收率为102.8%,RSD为1.15%。[结论]该方法快速,重现性好,准确度高,操作简便,可用于白蔹药材的质量控制。

摘  要:
[Objective] To establish an RP-HPLC method for determination of gallic acid in Ampelopsis japonica. [Method] The analysis was carried out on an Dikma Diamonsil C18column(250 × 4. 6 mm,5 μm) and the mobile phase was acetonitrile-0. 2% phosophorie acid(3∶ 97)at the flow rate of 1. 0 ml / min; the detection wavelength was 270 nm and the column temperature was 30 ℃. [Result] The linear range for gallic acid was 3. 15-202 μg / ml(R2= 0. 999 9). The average recovery was 102. 8%(RSD = 1. 15%). [Conclusion] This method is simple,rapid,accurate,and it can be used for the quality control of the prepared slices of Ampelopsis japonica.
