摘要: | 目的:建立11批广西倒地铃的指纹图谱并考察其体外抗氧化活性的谱效关系,为揭示其抗氧化活性物质基础提供参考。方法:采用高效液相色谱法建立11批广西倒地铃的指纹图谱,采用1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除法测定不同产地倒地铃的体外抗氧化活性,并运用双变量相关性分析法考察倒地铃体外抗氧化的谱效关系。结果:11批广西倒地铃图谱的相似度均大于0.9,16个共有峰中2(原儿茶酸)、3、4、12号峰含量变化与DPPH自由基清除活性大小密切相关。结论:广西不同产地倒地铃的化学成分基本一致,但产地不同时质量有一定差异;原儿茶酸(2号峰)及3、4、12号峰代表的未知化合物可能是其抗氧化活性的药效物质基础。 |
ABSTRACT: | OBJECTIVE: To establish the fingerprints of 11 batches of Cardiospermum halicacabum from Guangxi, and detect its spectrum-effect relationship of antioxidant activity in vitro, and provide reference for revealing the material basis for its antioxidant activity. METHODS: HPLC was conducted to establish the fingerprints of 11 batches of C. halicacabum from Guangxi, the 1,1-diphenyl-2-trinitrobenzene hydrazine (DPPH) free radical scavenging method was used to determine the antioxidant activity in vitro of C. halicacabum from different origins, and bivariate correlation analysis was adopted to detect the spectrum-effect relationship of antioxidant activity in vitro. RESULTS: The similarities of 11 batches of C. halicacabum from Guangxi were all more than 0.9, and the content change of peak 2 (protocatechuic acid), 3, 4, 12 in 16 common peaks was closely related to the DPPH free radical scavenging activity. CONCLUSIONS: The chemical composition of C. halicacabum from different origins in Guangxi is basically consistent, while there are some differences in the quality of the producing area. The protocatechuic acid (peak 2) and the unknown compounds represented by peak 3, 4, 12 may be the pharmacodynamic material basis of its antioxidant activity. |
