摘要
为了比较不同道地产区艾叶化学成分差异,共收集了3个主要道地产区(河北安国、河南南阳、湖北蕲春)共24批艾叶药材。采用超高效液相色谱法(UPLC)对艾叶药材中13个非挥发性成分的含量进行了测定和比较;进一步采用顶空气相色谱质谱联用法(HS-GC-MS)对艾叶药材中的挥发性成分进行定性分析和比较。结果表明艾叶非挥发性成分中酚酸类成分的含量明显高于黄酮类成分,但3个道地产区艾叶药材中非挥发性成分含量差异不明显;而3个道地产区艾叶药材中挥发性成分种类虽无显著差异,均含所鉴定出的40种挥发性成分,但在各挥发性成分相对含量上有显著差异;进一步运用主成分分析和偏最小二乘判别分析对不同道地产区艾叶的挥发性成分进行分析,共寻找到8个挥发性差异化合物,可以作为区分3个道地产区艾叶药材的指标性成分。通过以上研究,明确了不同道地产区艾叶药材的化学成分差异,为艾叶药材道地产地区分和质量评价提供了分析方法和科学依据。
This study aims to compare the chemical constituents in 24 batches of Artemisiae Argyi Folium samples collected from three different Dao-di producing areas(Anguo in Hebei,Nanyang in Henan,and Qichun in Hubei).An ultra-performance liquid chromatography(UPLC) method was established to determine the content of 13 nonvolatile components,and headspace-gas chromatography-mass spectrometry(HS-GC-MS) was employed for qualitative analysis and comparison of the volatile components.The content of phenolic acids in Artemisiae Argyi Folium was higher than that of flavonoids,and the content of nonvolatile components showed no significant differences among the samples from the three Dao-di producing areas.A total of 40 volatile components were identified,and the relative content of volatile components in Artemisiae Argyi Folium was significantly different among the samples from different Dao-di producing areas.The principal component analysis and partial least squares discriminant analysis identified 8 volatile components as the potential markers for discrimination of Artemisiae Argyi Folium samples from different Dao-di producing areas.This study revealed the differences in the chemical composition of Artemisiae Argyi Folium samples from three different Dao-di producing areas,providing analytical methods and a scientific basis for the discrimination and quality evaluation of Artemisia Argyi Folium in different Dao-di producing areas.
