| 中文摘要: |
| 研究了超声波辅助提取牡丹籽油。采用单因素试验研究提取次数、液料比、提取温度、提取时间对牡丹籽油提取率的影响；分别以牡丹籽油提取率和综合评分为指标，采用正交试验优化超声波辅助提取牡丹籽油的工艺条件。结果表明：以综合评分为评价指标更具优势，其兼顾了提取牡丹籽油的提取率和品质，更为全面和合理。以综合评分为指标，最优提取条件为液料比4∶?1、提取温度40?℃、提取时间50 min、提取次数2次。在最优条件下，牡丹籽油提取率、牡丹籽油中α-亚麻酸和亚油酸含量分别为93.1%、31.7%和26.8%。 |
| 英文摘要: |
| The ultrasound - assisted extraction of oil from Paeonia suffruticosa Andr. seed was studied. The effects of extraction times, ratio of liquid to solid, extraction temperature and extraction time on the extraction rate of Paeonia suffruticosa Andr. seed oil were studied by single factor experiment. With extraction rate and comprehensive score of Paeonia suffruticosa Andr. seed oil as indexes respectively, the ultrasound-assisted extraction conditions of Paeonia suffruticosa Andr. seed oil were optimized by orthogonal experiment. The results showed that the comprehensive score was superior to extraction rate, and it was more comprehensive and reasonable to take into account the extraction rate and quality of Paeonia suffruticosa Andr. seed oil.With comprehensive score of Paeonia suffruticosa Andr. seed oil as index, the optimal extraction conditions were obtained as follows: ratio of liquid to solid 4∶?1, extraction temperature 40?℃，extraction time 50 min, and extraction times twice. Under these conditions, the extraction rate, contents of α-linolenic acid and linoleic acid in Paeonia suffruticosa Andr. seed oil were 93.1%, 31.7% and 26.8%, respectively. |
