目的 采用主成分分析和判别分析对不同产地枳壳药材中12种有效化学成分的HPLC的含量测定结果进行分析比较,以鉴别区分其产地来源。方法 以异柚皮苷、柚皮苷、橙皮苷、新橙皮苷、水合橘皮内酯、柚皮素、橙皮素、橘皮内酯、马尔敏、川陈皮素、橘皮素及葡萄内酯为指标,用HPLC法进行含量测定,并对其含量进行主成分分析和判别分析。结果 主成分分析结果表示各产地的枳壳药材具有一定的相似性,且江西产地的枳壳药材含量较为稳定;判别分析结果表明,江西樟树、宜春,湖南沅江、怀化和浙江金华、兰溪产地的枳壳样品可以区分开来,而江西新干和浙江金华、兰溪产地的枳壳样品有重叠。结论 本方法简单、方便、可靠,可用于初步筛选出适合枳壳生长的地区,以期为进一步阐述枳壳药材的道地性奠定基础。

Objective To analyze and compare the contents of 12 effective chemical constituents in Aurantii Fructus from different areas, and identify their source of origin by using principal component analysis and discriminant analysis. Methods Using isonaringin, narigin, hesperidin, neohesperidin, meranzin hydrate, naringin, hesperidin, meranzin, marmin, nobiletin, tangeretin, and auraptene as index, HPLC method was used to determine the content, and the average percentage content was analyzed by principal component analysis and discriminant analysis. Results Principal component analysis results showed that Aurantii Fructus from different areas had certain similarities, and the content of Aurantii Fructus from Jiangxi Province was relatively stable. Discriminant analysis results showed that the samples from Zhangshu, Yichun, Yuanjiang, Huaihua, Jinhua, and Lanxi could be distinguished, while the samples from Xin'gan in Jiangxi, Jinhua, and Lanxi in Zhejiang overlapped. Conclusion This method is simple, convenient and reliable, which can be used to screen out the suitable areas for the growth of Aurantii Fructus, so as to lay a foundation for explaining the authenticity of Aurantii Fructus.
