【目的】以不同提取工艺下芹菜籽油的得油率及芹菜甲素、总酞内酯的含量评价各提取工艺。【方法】采用有机溶剂提取法、索氏提取法、水蒸气蒸馏法3大常规方法及亚临界和超临界提取法提取芹菜籽油。并分别采用高效液相色谱法及紫外可见分光光度法考察芹菜籽油中芹菜甲素及总酞内酯的含量。【结果】不同提取工艺下芹菜籽油得油率、芹菜甲素与总酞内酯的含量差别较大,范围分别为0.30%~20.02%、1.40%~10.13%、4.74%~17.65%。【结论】提取芹菜甲素以R134a与丁烷为溶剂的亚临界提取工艺为佳,芹菜甲素转移率相当;提取总酞内酯则以二甲醚为溶剂的亚临界提取法为优。
【Objective】 The extraction rate of celery seed oil and the contents of celery a and total phthalide in different extraction processes were evaluated. 【Method】 Three kinds of common methods such as organic solvent extraction, Soxhlet extraction and steam distillation were used to extract celery seed oil by subcritical and supercritical fluid extraction. The contents of celerychin and total phthalide in celery seed oil were determined by HPLC and UV-vis spectrophotometry respectively. 【Result】 The results showed that the content of celery a and total phthalide varied greatly from 0.30% to 20.02%, 1.40% ~ 10.13% and 4.74% ~ 17.65%, respectively. 【Conclusion】 The subcritical extraction of celery melatonin with R134a and butane as solvent was better, and the transfer rate of celery a was similar. The extraction of total phthalide with dimethyl ether as solvent was superior.
