摘要: 研究超声波-表面活性剂协同提取竹叶总黄酮的工艺。在单因素试验的基础上,采用响应面法研究超声功率、表面活性剂浓度和液固比对竹叶总黄酮得率的影响。结果表明,在超声频率40kHz和常温下,超声波-表面活性剂协同提取竹叶总黄酮的最佳工艺为超声功率420W、十二烷基硫酸钠物质的量浓度25.20×10-3mol/L、液固比23:1(mL/g,表面活性剂溶液:竹叶粉末),此时竹叶总黄酮得率达2.30%。

Abstract: The ultrasonic-assisted surfactant extraction of total flavonoids from bamboo leaves was optimized by one-factor-at-a-time method and response surface methodology. The extraction yield of total flavonoids was investigated with respect to ultrasound power, surfactant type, surfactant critical micelle (CMC) concentration and solvent-to-solid ratio. The results showed that the optimal conditions for the extraction of total flavonoids at 40 kHz ultrasonic power and ambient temperature were ultrasound power of 420 W, SDS as the extraction surface at a CMC of 25.20×10-3 mol/L, and a solvent-to-solid ratio of 23:1 (mL/g) (ratio of SDS solution to bamboo leaves). Under these conditions, the yield of total flavonoids was 2.30%.
