摘要
为优化生姜中姜辣素的超声辅助提取工艺,对乙酸乙酯、提取温度、液料比、提取时间进行单因素试验的基础上,运用Box-Behnken中心组合试验和响应面法考察液料比、提取温度和乙酸乙酯体积分数对姜辣素得率的影响。优化后的最佳提取工艺为:液料比19.3 mL/g,提取温度41.5℃,乙酸乙酯体积分数91.5%。此条件下,生姜中姜辣素得率为22.982 mg/g,说明用响应面法优化超声辅助提取生姜中姜辣素的工艺可行。
In order to optimize the process of ultrasonic-assisted extraction of gingerol,the single factor test of ethyl acetate volume fraction,extraction temperature,liquid-solid ratio,extraction time were first conducted.Then,the effects of liquid-solid ratio,extraction temperature and ethyl acetate volume fraction on extraction yield were studied by Box-Behnken test design and response surface method.The optimal gingerol extraction process is： liquid to solid ratio 19.3 mL/g,extraction temperature 41.5 ℃,ethyl acetate volume fraction 91.5%.The gingerol extraction yield is 22.982 mg/g.Therefore,the process of ultrasonic-assisted extraction of gingerol optimized by response surface method is very reliable.
