| 摘 要： | 以向日葵花瓣为原料,选用醇提法提取向日葵花瓣中绿原酸,在单因素实验的基础上,通过正交试验对工艺条件进行优化,结果表明,向日葵花瓣中绿原酸最佳提取条件:温度50℃,乙醇体积分数70%,pH值6,料液比1∶20,回流时间30 min,此时,提取率可达1.801%。抗氧化性研究表明:向日葵花瓣中绿原酸提取液对超氧阴离子具有一定的清除作用,且效果比Vc好。

| Abstract: | Chlorogenic acid was obtained from helianthus annuus L petals via extraction method using al-cohol as the solvent. The extraction parameters were optimized through orthogonal experimental method af-ter a single-factor test. The results showed that a maximum chlorogenic acid yield of 1.801%was obtained under the optimum conditions, i.e. temperature of 50 ℃, ethanol volume fraction of 70%, pH value of 6, a solid/liquid ratio of 1：20 （g/mL） and extraction time for 30 min. Antioxidant activity test showed that chlorogenic acid from helianthus annuus L petals possessed better scavenging capability of ultra-oxygen anion O2-＆#183;than Vc. |
