摘 要:目的:研究芫荽总黄酮的大孔树脂纯化工艺及总黄酮抗氧化、抗菌活性。方法:通过筛选优化大孔树脂型号,优化大孔树脂提取芫荽总黄酮条件,利用DPPH芫荽总黄酮抗氧化活性,琼脂扩散法测试芫荽总黄酮抗菌活性。结果:AB-8树脂对芫荽总黄酮有较好的吸附和解吸效果,最优工艺条件为:芫荽总黄酮上样液的质量浓度为1.5 mg/mL,上样速率为2 mL/min,洗脱剂为70%乙醇,洗脱剂用量为4BV,洗脱速率为2mL/min,芫荽黄酮提取物清除DPPH·自由基的EC50为1.5mg/mL。对枯草芽孢杆菌、金黄色葡萄球菌、大肠杆菌、绿脓杆菌、黑曲霉均有抗菌活性,但是对酿酒酵母无效。结论:AB-8型大孔树脂富集芫荽总黄酮效果最佳。Objective: To investigate the purification technology of total flavonoids with macroporous resin and to study the antibacterial and antioxidant activity of total flavonoids from Coriandrum sativum L.. Method: Screen the optimal macroporous resin and optimize the purification technology of total flavonoids from Coriandrum sativum L. , then use the DPPH method to test the antioxidant activity and agar-diffusion method to test the antibacterial activity of total flavonoids from Coriandrum sativum L.. Results: AB-8 resin has excellent effect on the adsorption and desorption of total flavonoids from Coriandrum sativum L.. The sample concentration is 1. 5 mg/mL and the rate is 2 mL/min, the eluent is 70; ethanol of 4 BV and rate of 2 mL/min, which are the optimal purification process conditions. The total flavonoids from Coriandrum sativum L. also has excellent antioxidant activity (EC50 = 1. 5 mg/mL), and the antibacterial activity against Bacillus subtilis, Staphylococcus aureus , Escherichia coli , Pesudomonas aeruginosa , Aspergillus niger, but not against Saccharomyces cerevisiae.
