摘要
目的:研究漏芦化学成分和抗胃癌药效之间的谱效关系。方法:采用HPLC分析7种产地漏芦的化学成分,对共有峰进行主成分分析,根据相关系数矩阵、特征值和累计方差贡献率,初步推断漏芦的主成分;采用噻唑蓝法检测7种产地漏芦抑制胃癌细胞SGC-7901和AGS增殖的作用,对7批漏芦进行聚类分析;利用典型相关分析对漏芦成分、药效数据进行相关分析。结果:在漏芦17个共有峰中,主成分为迷迭香酸、齐墩果酸和豆甾醇。7个产地漏芦抑制SGC-7901细胞和AGS细胞增殖的作用顺序均为河南>山东>辽宁>山西>安徽>江苏>甘肃。聚类分析显示河南和山东产地为1类,辽宁和山西产地为1类,安徽、江苏和甘肃产地为1类。结论:河南产地的漏芦抑制胃癌细胞SGC-7901和AGS增殖的作用最强,漏芦抗胃癌的主成分可能为迷迭香酸、齐墩果酸、豆甾醇等。
