TITLE: | Simultaneous Determination of 6 Medicinal Components in Mango Zhike Tablets by Quantitative Analysis of Multi-components by Single Marker Method |
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PhenomenexGeminiC18,流动相为0.1%磷酸水溶液-乙腈(梯度洗脱),流速为1.0mL/min,检测波长为258nm,柱温为30℃,进样量为5μL。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量浓度的线性范围分别为45.75~1830μg/mL(r=0.9999)、2.525~101.0μg/mL(r=0.9999)、65.33~2613μg/mL(r=0.9996)、9.058~362.3μg/mL(r=0.9999)、3.885~155.4μg/mL(r=0.9999)、1.870~74.8μg/mL(r=0.9999);定量限分别为0.571、0.643、1.053、0.854、0.830、1.500μg/mL,检测限分别为0.171、0.193、0.316、0.256、0.249、0.450μg/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%(RSD=0.9%,n=6)、98.2%~101.6%(RSD=1.2%,n=6)、102.3%~106.1%%(RSD=1.3%,n=6)、96.6%~99.3%(RSD=1.0%,n=6)。以没食子酸为内参物,原儿茶酸、芒果苷、高芒果苷、金丝桃苷、异槲皮苷的相对校正因子分别为0.5683、0.5003、0.6876、0.9391、0.8263;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、0.115~0.293mg/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、0.119~0.298mg/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 C 18 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 μL. 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% (RSD=1.2%,n=6),102.3%-106.1%(RSD=1.3%,n=6), 96.6% -99.3%(RSD=1.0% ,n=6),respectively. RCFs of 73) protocate-chuic acid , mangiferin, homomangiferin,hyperoside and isoquercetin were 0.568 3,0.500 3,0.687 6, 0.939 1 and 0.826 3,using gallic acid as internal substance . The content ranges of protocatechuic acid and other 4 com- ponents measured by QAMS were 0.197-0.440,3.262-11.250, 0.201-1.196,0.168-0.381,0.115-0.293 mg/tablet,respectively. The content ranges measured by ESM were 0.198-0.441,3.239-11.570,0.206-1.194,0.171-0.380,0.119-0.298 mg/tablet, respectively. By comparing the content determination results by QAMS and ESM ,the relative errors were -3.80%-0.74%,and there was no statistical significance (P>0.05). CONCLUSIONS :The established QAMS method is accurate ,reliable and repeatable,and can be used for content determination of 6 medicinal components in Mangguo zhike tablets. |
