摘要
文中研究了山竹果皮中原花青素的超声辅助提取工艺条件。通过单因素试验分析超声提取过程中超声功率、料液比、乙醇浓度、提取时间和温度等因素对原花青素提取率的影响,在此基础上,采用L9(34)正交试验优选出山竹果皮中原花青素提取的最佳条件。结果表明:各因素对原花青素提取率的影响大小顺序为乙醇浓度(B)>温度(C)>料液比(A)>时间(D);最佳工艺条件为料液比为1∶30,乙醇体积分数60%,提取温度50℃,提取时间45 min,此条件下山竹果皮中原花青素的提取率为15.61%。
To study the extraction conditions for Proanthocyanidins assited by ultrasonic wave from Garcinia mangostana L peel . Effects of ultrasonic power, solid-liquid ratio, ethanol concentration, and extraction time and extraction temperature on the extraction rate were studied by single factor test. Then the optimum extraction condition was opti- mized by L9 (34) orthogonal test. The influence order of these factors on the extraction rate of proanthoeyanidins was: ethanol concentration (B) 〉 extraction temperature(C) 〉 solid-liquid ration(A) 〉 extraction time(D). The optimal ex- traction condition was: solid-liquid ratio 1:30 (g: mL), the concentration of ethanol 60% , the extraction time 30 mi- nutes at 50~C. Under the optimum conditions, the yield of proanthoeyanidins in Garcinia mangostana L peel was 15.61%.
