摘　　要：建立伏毛铁棒锤的HPLC指纹图谱,并对4种生物碱成分进行含量测定,为不同产地伏毛铁棒锤药材质量评价提供参考。采用ACE excel C_(18) PFP(4.6 mm×250 mm,5μm),以乙腈(A)-0.1%磷酸溶液(1000 mL加2.5 mL三乙胺)(B)为流动相,梯度洗脱,流速1.0 mL/min,柱温35℃,检测波长215 nm,进样量10μL。共标定了18个共有峰,指认了12-表欧乌头碱、宋果灵、乌头碱和3-乙酰乌头碱,质量分数分别为0.0108~1.7845、0.0113~3.1234、0.0184~2.5981、0.0188~0.6557 mg/g。聚类分析将15批样品分为4类,主成分分析筛选出了5个主成分,累计方差贡献率为82.549%,说明主成分能够综合伏毛铁棒锤药材成分的大部分信息。15批样品相似度范围在0.769~0.952,说明不同批次伏毛铁棒锤样品的差异性较大。该方法可以有效评价不同产地伏毛铁棒锤药材的质量差异,为其质量控制提供参考。HPLC fingerprints of Aconitum flavum Hand.-Mazz.were established,and the contents of four alkaloids were determined to provide reference for the quality evaluation of A.flavum in different production areas.The analysis was performed on Ace excel C_(18) PFP(4.6 mm×250 mm,5μm)with acetonitrile(A)-0.1%phosphoric acid solution(add 2.5 mL triethylamine per 1000 mL)(B)as mobile phase in a gradient elution mode.The flow rate was 1.0 mL/min,the column temperature was 35℃,the detection wavelength was set at 215 nm and the injection volume was 10μL.There were 18 common peaks in the HPLC chromatogram of 15 batches of A.flavum,among which the percentages of 12-epinapelline,songrine,aconitine and 3-acetylaconitine were as follows:0.0108-1.7845,0.0113-3.1234,0.0184-2.5981 and 0.0188-0.6557 mg/g.According to the cluster analysis,the 15 batches of A.flavum were classified into four categories,principal component analysis(PCA)screened out five principal components,with the cumulative variance contribution rate of 82.549%,indicating that the principal components contained most information of original data.The similarity of 15 batches of A.flavum ranged from 0.769 to 0.952,indicating that there was difference between batches of A.flavum.This method can effectively evaluate the quality difference of A.flavum from different producing areas,and provide reference for the quality control of medicinal materials.
