| 中文摘要: |
| 旨在促进葵花籽饼的高值化利用，采用低共熔溶剂（DES）提取葵花籽饼中绿原酸和总黄酮。以60%乙醇提取法为对照，绿原酸和总黄酮得率为评价指标，先从11种DES中确定最佳提取溶剂，在此基础上进一步考察提取时间、料液比、提取温度、DES含水量对绿原酸和总黄酮提取效果的影响，从而确定绿原酸和总黄酮的最优提取工艺。结果表明：综合考虑提取效果和成本，确定氯化胆碱-乳酸（物质的量比1∶ 2）为最佳提取溶剂；绿原酸的最优提取工艺条件为提取时间60 min、提取温度70 ℃、料液比1∶ 30和DES含水量30%，总黄酮的最优提取工艺条件为提取时间40 min、提取温度80 ℃、料液比1∶ 40和DES含水量50%；在最优工艺条件下，绿原酸和总黄酮得率分别达到18.88 mg/g和38.04 mg/g，明显高于60%乙醇提取法。综上，采用DES法可有效提取葵花籽饼中的绿原酸和总黄酮，提取效果均优于传统乙醇提取法。 |

| In order to promote the high-value utilization of sunflower seed cake, chlorogenic acid and total flavonoids were extracted from sunflower seed cake by deep eutectic solvent(DES). Using 60% ethanol extraction method as the control, and the yields of chlorogenic acid and total flavonoids as the evaluation indexes, the optimal extractant was determined from 11 DES firstly. On this basis, the effects of extraction time, material-liquid ratio, extraction temperature and water content in DES on the extraction efficiency were further investigated to determine the optimal extraction processes of chlorogenic acid and total flavonoids. The results showed that considering both extraction effect and cost, choline chloride-lactic acid (molar ratio 1∶ 2) was determined as the optimal extractant. The optimal extraction conditions for chlorogenic acid were obtained as follows:extraction time 60 min, extraction temperature 70 ℃, material-liquid ratio 1∶ 30 and water content in DES 30%. The optimal extraction conditions for total flavonoids were obtained as follows: extraction time 40 min, extraction temperature 80 ℃, material-liquid ratio 1∶ 40 and water content in DES 50%. Under these conditions, the yields of chlorogenic acid and total flavonoids could reach 18.88 mg/g and 38.04 mg/g, respectively, which were significantly higher than those of the 60% ethanol extraction method. In conclusion, the DES method is more effective in extracting chlorogenic acid and total flavonoids from sunflower seed cake than the traditional ethanol extraction method. |
