摘 要 目的:建立同时测定芒果止咳片中没食子酸、原儿茶酸、芒果苷、高芒果苷、金丝桃苷和异槲皮苷含量的方法。方法:采用
高效液相色谱法。色谱柱为 Phenomenex Gemini C18,流动相为 0.1%磷酸水溶液-乙腈(梯度洗脱),流速为 1.0 mL/min,检测波长
为258 nm,柱温为30 ℃,进样量为5 μL。以没食子酸为内参物,计算原儿茶酸、芒果苷、高芒果苷、金丝桃苷和异槲皮苷的相对校
正因子,并将一测多评法与外标法测定结果进行比较。结果:没食子酸、原儿茶酸、芒果苷、高芒果苷、金丝桃苷和异槲皮苷检测质

9.058~362.3 μg/mL(r=0.999 9)、3.885~155.4 μg/mL(r=0.999 9)、1.870~74.8 μg/mL(r=0.999 9);定量限分别为 0.571、0.643、
1.053、0.854、0.830、1.500 μg/mL,检测限分别为0.171、0.193、0.316、0.256、0.249、0.450 μg/mL;精密度、稳定性、重复性试验RSD均
小于 3%;加样回收率分别为 98.8%~101.9%(RSD=1.3%,n=6)、94.3%~101.5%(RSD=3.3%,n=6)、97.9%~100.5%

0.687 6、0.939 1、0.826 3;一测多评法测得原儿茶酸等 5 种成分的含量范围分别为 0.197~0.440、3.263~11.250、0.201~1.196、
0.168~0.381、0.115~0.293 mg/片,外标法测得的含量范围分别为 0.198~0.441、3.329~11.570、0.206~1.194、0.171~0.380、
0.119~0.298 mg/片,两种方法测量结果的相对误差为-3.80%~0.74%,且差异无统计学意义(P>0.05)。结论:所建一测多评含
量测定方法准确、可靠、重复性好,可用于同时测定芒果止咳片中6种药效成分的含量。

ABSTRACT OBJECTIVE:To establish a method for simultaneous determination of gallic acid,protocatechuic acid,mangiferin,
homomangiferin,hyperoside and isoquercetin in Mangguo zhike tablets. METHODS:HPLC was adopted. The determination was
performed on Phenomenex Gemini C18 column with mobile phase consisted of 0.1% phosphoric acid water solution-acetonitrile
(gradient elution)at the flow rate of 1.0 mL/min. The detection wavelength was set at 258 nm. The column temperature was set at
30 ℃ ,and sample size was 5 μ L. Gallic acid was used as the internal substance,and the correction factors of gallic acid,
protocatechuic acid,mangiferin,homomangiferin,hyperoside and isoquercetin were calculated;the results of quantitative analysis
of multi-components by single marker method (QAMS) were compared with those of external standard method (ESM).
RESULTS:The linear range of gallic acid,protocatechuic acid,mangiferin,homomangiferin,hyperoside and isoquercetin were
45.75-183 0 μg/mL(r=0.999 9),2.525-101.0 μg/mL(r=0.999 9),65.33-261 3 μg/mL(r=0.999 6),9.058-362.3 μg/mL(r=
0.999 9),3.885-155.4 μg/mL(r=0.999 9),1.870-74.8 μg/mL(r=0.999 9),respectively. The limits of quantification were 0.571,
0.643,1.053,0.854,0.830,1.500 μg/mL,respectively. The limits of detection were 0.171,0.193,0.316,0.256,0.249,0.450 μg/mL,
respectively. RSDs of precision, stability and reproducibility tests were all lower than 3% . The average recoveries were
98.8%-101.9%(RSD=1.3% ,n=6),94.3%-101.5%(RSD=3.3%,n=6),97.9%-100.5%(RSD=0.9%,n=6),98.2%- 101.6%
