【摘要】 目的:为阐明维药神香草抗炎作用的药效物质基础提供参考。方法:采用高效液相色谱法建立神香草8个不同极性提取物的指纹图谱;以巨噬细胞RAW264.7为研究对象,考察神香草不同极性提取物对细胞培养上清液中炎症因子一氧化氮(NO)、肿瘤坏死因子α(TNF-α)和白细胞介素6(IL-6)的抑制作用,比较其体外抗炎活性的差异性;采用灰色关联分析法分析指纹图谱共有峰的峰面积与抗炎活性的谱-效关系。结果:神香草8个不同极性提取物的指纹图谱具有明显的差异。体外抗炎结果提示,神香草30%乙醇提取物对体外炎症因子的抑制作用最强。对其建立的HPLC指纹图谱有共有峰14个,与体外炎症因子的抑制作用关系密切的5个共有峰分别为8、6、5、10、13号,其中8号峰为迷迭香酸。结论:所建立的指纹图谱及其与体外抗炎活性的谱效关系可为该药材的药效物质基础研究提供一定参考。更多还原

【Abstract】 OBJECTIVE:To provide reference for clarifying the pharmacodynamic material basis of anti-inflammation effect of Uygur medicine Hyssopus cuspidatus. METHODS:HPLC was conducted to establish the fingerprint of 8 extracts with different polarities. Using macrophage RAW264.7 as object,the inhibitory effect of extracts with different polarities on inflammatory factor nitric oxide(NO),TNF-α and IL-6 in supernatant of cell culture medium was detected,the differences of anti-inflammatory activity in vitro were compared. Grey correlation analysis method was used to analyze the spectrum-effect relationship of peak area of common peaks and anti-inflammation activity. RESULTS:The fingerprint of 8 extracts with different polarities showed obvious differences. Anti-inflammation in vitro results suggested that 30% ethanol extract had the strongest inhibitory effect on inflammatory cytokines in vitro. There were 14 common peaks in the established HPLC fingerprints,the 5 common peaks that was closely related tothe inhibitory effect of inflammatory factors in vitro were peak 8,6,5,10,13,respectively;peak 8 was rosmarinic acid. CONCLUSIONS:The established fingerprint and its spectrum-effect relationship with anti-inflammation activity in vitro can provide certain reference for its pharmacodynanic material basis study.更多还原
