摘要: 通过比较溶剂浸提法、超声波法和闪式提取法提取玫瑰花色素,结果显示闪式提取法提取玫瑰花色素具有最高的效率。在单因素试验的基础上,以玫瑰花色素的提取率为参考指标,选取提取时间、液料比和闪提电压三个影响因子,进行正交试验。确定正交试验优选玫瑰花色素最佳闪提条件为:提取时间为55s,料液比1:60(g/mL),电压为120 V。经过聚酰胺树脂和XAD大孔树脂的纯化,玫瑰花色素的收率达到4.463%。经过滤纸过滤分离,得到玫瑰花色苷和花色苷元,收率分别为2.331%和2.131%。本研究为高效、简便的提取玫瑰花色苷和花色苷元提供参考。

Abstract: In this study,solvent extraction,ultrasonic extraction and flash extractionwas used for the extraction of rose pigment,in which flash extraction showed the highest efficiency.Based on single factor experiments,the effects of extraction time,liquid to solid ratio and extraction voltage on the yield of rose pigment were investigated,and orthogonal experiments were applied to further optimize extraction conditions.The results showed that the optimal conditions of flash extraction were confirmed as follows:flash extraction for 55 seconds,solid to liquid ratio of 1:60 g/mL,and voltage of 120 V.The crude rose pigment was further separated by polyamide resin and XAD macroporous resin.The concentration of rose pigment in the purified extract was 4.463%.Through further separation,the concentration of anthocyaninswas 2.331% and the anthocyanidins was 2.131%.These results provided the basis for the extraction of anthocyanins and anthocyadins,efficiently and simply.
