中文摘要: 采用超声波辅助提取荷花粉中的总黄酮,利用单因素试验和响应面方法优化总黄酮的最佳提取工艺,研究 液固比、乙醇浓度、超声处理温度和提取时间对总黄酮提取率的影响。结果表明,当超声波功率 250 W 条件下,超声 波辅助提取荷花粉总黄酮最佳工艺参数为液固比 18.5(mL/g),乙醇浓度 82 %,提取温度 74 ℃,提取时间 53 min,总 黄酮的提取率可达 1.658 2 %。
Abstract:This study aimed to optimize the ultrasonic treatment parameters for total flavonoids extracted from lotus power by single factor tests and response surface methodology. Effects of liquid-solid ratios, ethanol con- centration, ultrasonic treatment temperature and time on extraction yield of total flavonoids were studied. Re- sults showed that the optimum ultrasonic assisted extraction parameters were liquid-solid ratios of 18.5(mL/g), ethanol concentration of 82 %, ultrasonic treatment temperature of 74 ℃, extraction time of 53 min under ultra- sonic power 250 W. Extraction yield of total flavonoids achieved 1.658 2 % under the optimum parameters.
