摘要: 研究玉米须总黄酮抗糖基化、乙酰胆碱酯酶和α-葡萄糖甘酶抑制活性。采用内部沸腾法提取玉米须总黄酮,优化其工艺条件,并对其进行分析。在单因素实验基础上,采用Plackett-Burman法对7个相关因素进行评价,筛选出具有显著性差异的4个因素,并对其进行响应面优化。结果表明,内部沸腾法提取玉米黄酮最佳条件为解析时间16 min,解析剂浓度73%,提取时间20 min,提取温度为61 ℃,总黄酮提取得率为4.75±0.69%;玉米须黄酮对晚期糖基化终产物、乙酰胆碱酯酶和α-葡萄糖苷酶具有一定抑制效果,呈现浓度依赖性,IC50分别为467.90、73.07、151.04 μg/mL。抗糖基化、乙酰胆碱酯酶和α-葡萄糖甘酶抑制活性与黄酮含量呈正相关(相关系数分别为0.83、0.90和0.87;P<0.05),该研究结果可为潜在的天然产物抑制剂开发提供理论依据。

Abstract: To study the antiglycation activity,acetylcholine esterase and α-glucosidase inhibitory activity of total flavonoids from corn silk.Seven parameters potentially influencing the extraction yield of total flavonoids were screened through Plackett-Burman design to determine the significant variables.Then,factors effecting on extraction yield were further optimized using Box-Behnken design to predict optimum extraction conditions.Satisfactory yield of total flavonoids (4.75±0.69%)was achieved using the optimal conditions.16 min of desorption time,73% of ethanol indesorption solvent,20 min of extraction time,and 61 ℃ of extraction temperature were selected and applied for effective extraction.It also exhibited the certain antiglycation,inhibitory activity against acetylcholine esterase and α-glucosidase in a concentration-dependent manner with IC50 of 467.90,73.07,and 151.04 μg/mL,respectively.Antiglycation activity,acetylcholine esterase and α-glucosidase activity inhibitory activity were positively correlated with the content of total flavonoids,whose correlation coefficients are 0.83,0.90 and 0.87 respectively,P<0.05.It can provide a theoretical basis for the development of natural inhibitors.
