目的:建立UPLC同时测定白术中3种白术内酯成分含量分析方法。方法:样品以甲醇超声提取30 min进行处理。采用超高效液相色谱,以Agilent Poroshell 120 EC-C18(3.0 mm×150 mm,2.7 μm)为色谱柱,流动相水(A)-甲醇(B)梯度洗脱,流速0.5 mL?min-1,柱温30℃,检测波长220 nm和276 nm,进样量3 μL。采用IBM SPSS 27.0软件对24批白术进行聚类分析和主成分分析。结果:3个成分在考察的浓度范围内,浓度与峰面积之间呈良好的线性关系(r﹥0.999),回收率均在103.05%~106.35%,RSD 2.0%~3.3%。经聚类分析发现,24批白术药材可聚为四大类;经主成分分析发现,2个主成分因子的累计方差贡献率为98.975%(第一主成分、第二主成分的贡献率分别为92.124%、6.601%)。结论:该方法简便、快捷、准确且灵敏度高,对评控白术药材的质量提供参考。 |

Objective: To establish a UPLC method for the simultaneous determination of three Atractylenolides in Atractylodes macrocephala. Method: The samples were extracted with methanol for 30 minutes by ultrasonic method .Three compounds in A. macrocephala were simultaneously determined by UPLC with Agilent Poroshell 120 EC-C18(3.0 mm×150 mm,2.7 μm),with water ( A) - methanol ( B) as the mobile phase for gradient elution; at the flow rate of 0.5 mL?min-1; the determination wavelength was 220 nm and 276 nm; and the injection volume was 3 μL. Cluster analysis and principal compoent analysis were performed by IBM SPSS 27.0 statistical software. Result: There was a good linear relationship between the concentration and peak area of all the three components in the investigated concentration range ( r>0.999) . The average recoveries ranged from 103.05% to 106.35% with RSD of 2.0%-3.3%. Through cluster analysis, 24 batches of A. macrocephala could be clutered into 4 groups. According to the principal component analysis,the cumulative variance contribution rate of the two principal component factors was 98.975%(contribution rates of first principal components and second principal components were 92.124% and 6.601%).Conclusion: The method is simple,rapid,accurate and highly sensitive to provide a reference for quality evaluation of A. macrocephala. |
