摘　　要：采用乙醇提取百香果皮中的原花青素,探讨反应时间、反应温度、固液比及乙醇体积分数对原花青素提取率的影响。结果表明,最佳提取工艺为:反应温度40℃,反应时间70 min,固液比1∶15 g/mL,乙醇体积分数55%,原花青素提取率1.82%,同时,于最佳工艺条件下探究了百香果籽中原花青素含量,结果表明,百香果籽中未含有原花青素成份。Proanthocynidins was extracted from passion fruit by ethanol extraction method,the effects of reaction temperature,extracting time,extractant amount and ethanol concentration on the extraction rate of proanthocynidins were evaluated.The result showed that the best conditions were:the largest extraction ratio of proanthocynidins was 1.82%on the conditions of reaction temperature 40℃,extracting time 70 min,solid-liquid ratio 1∶15 g/mL and ethanol concentration 55%,which showed the process had a remarkable effect.However,passion fruit seeds did not contain proanthocynidins.
