摘要: 【目的】确定超声波辅助醇提取法提取紫苏叶总黄酮的最佳条件,并研究其抗菌及抗氧化活性。【方法】利用单因素试验得到各因素最佳条件后,采用响应面分析法设计提取工艺优化试验,经Design-Expert 13.0分析,得到紫苏叶总黄酮最佳提取条件。以对金黄色葡萄球菌的抑菌效果为指标探究其抑菌能力,采用DPPH自由基和ABTS自由基清除试验探究其抗氧化活性。【结果】不同因素水平下,乙醇体积分数35%、液料比15:1(mL:g)、提取功率300 W和提取时间30 min时,紫苏叶总黄酮提取率最高,分别为2.72%、3.20%、2.76%、3.02%;响应面分析法优化后,乙醇体积分数36%、液料比17:1(mL:g)、超声功率303 W、提取时间33 min时,紫苏叶总黄酮提取率最高,可达(3.375±0.098)%。所得紫苏叶总黄酮提取液对金黄色葡萄球菌可产生明显抑菌圈,对DPPH自由基、ABTS自由基清除率最高分别可达97.86%、95.79%。【结论】紫苏叶总黄酮的最佳提取条件为乙醇体积分数36%、液料比17:1(mL:g)、超声功率303 W、提取时间33 min;紫苏叶总黄酮对金黄色葡萄球菌具有明显的抑制作用,且表现出良好的自由基清除能力。

Abstract: 【Objective】To determine the optimal conditions for ultrasound-assisted ethanol extraction of perilla leaf total flavonoids and to evaluate their antibacterial and antioxidant activities.【Methods】After determining the optimal conditions for each factor through single-factor experiments,response surface methodology was employed to design the extraction process optimization experiment,and the optimal extraction conditions for perilla leaf total flavonoids were determined using Design-Expert 13.0. The antibacterial capacity was assessed using the inhibitory effect on Staphylococcus aureus as an indicator,while antioxidant activity was evaluated through DPPH and ABTS free radical scavenging assays.【Results】Under different factor levels,the extraction yields of perilla leaf total flavonoids reached the highest values of 2.72%,3.20%,2.76%,and 3.02%,respectively,with the ethanol volume fraction of 35%,liquid-to-solid ratio of 15:1(mL:g),ultrasonic power of 300 W,and extraction time of 30 min. After optimization using response surface methodology,the extraction yield of perilla leaf total flavonoids reached a maximum of (3.375±0.098)% under the conditions of 36% ethanol volume fraction,liquid-to-solid ratio of 17:1(mL:g),ultrasonic power of 303 W,and extraction time of 33 min. The obtained perilla leaf total flavonoids extract exhibited a significant inhibition zone against Staphylococcus aureus,with maximum DPPH and ABTS free radical scavenging rates of 97.86% and 95.79%,respectively.【Conclusion】The optimal extraction conditions for perilla leaf total flavonoids are an ethanol volume fraction of 36%,liquid-to-solid ratio of 17:1(mL:g),ultrasonic power of 303 W,and extraction time of 33 min. The perilla leaf total flavonoids demonstrate significant inhibitory effects against Staphylococcus aureus and strong free radical scavenging capacity.
