摘 要:目的:分析大黄属药用植物的超高效液相色谱法(UPLC)特征图谱与抗HIV-1活性之间的相互关系。方法:采用HIV-1逆转录酶相关的核糖核酸酶H活性测定检测了大黄属16种22个样品的抗HIV-1活性;同时测定了22个样品的UPLC特征图谱;运用数理统计方法研究谱效相关性;并采用UPLC-TOF-MS/MS指认样品主要成分峰。结果:藏边大黄、苞叶大黄和河套大黄提取物有较好的抗HIV-1活性。谱效相关性研究表明4.74,7.99,21.18 min色谱峰与活性有一定相关性。结论:通过谱效研究,推测了有抗HIV-1活性的大黄属药用植物及其活性组分,为大黄属植物深层次的研究开发奠定了基础。Objective: To study the relationship between ultra-performance liquid chromatography (UPLC) fingerprints of Rheum species and their anti-HIV 1 activities. Method: Twenty two samples of 16 species belonging to genus Rheum from various sources were collected and analyzed in this study. Firstly they were assayed for the HIV-1 reverse transcriptase (RT) associated ribonuclease H (RNase H) activity. Secondly the fingerprints were established by an optimized UPLC method. Sample was analyzed by UPLC-TOF-MS/MS to identify major peaks. The possible relationship between UPLC fingerprints and anti-HIV 1 activities of Rheum species were deduced by mathematical statistics method. Result: Samples of R. austral, R. austral, R. hotaoense exhibited good anti-HIV 1 activities with IC50≤0.2 mg·L-1. The correlation of anti-HIV 1 activities and fingerprints showed that three compounds were the main bioactive components, and their retention times were 4.74, 7.99, 21.18 min, respectively. Conclusion: Compounds in Rheum species with possible anti-HIV 1 activities were deduced by spectrum-effect relationship study. This study supported for study of medicinal plants in Rheum.keywords:Rheum species
