不同提取工艺芹菜籽油得率及芹菜甲素和总酞内酯含量的研究

【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。

Influence of Extraction Methods on Oil Yield of Celery Seeds and Contents of 3-n-butylphthalide and Total Phthalocyanine Lactones in Celery Seed Oil

Objective To compare the oil yield of celery seeds and the contents of 3-n-butylphthalide and the total phthalocyanine lactones of celery seed oil extracted by different methods. Methods Three routine extraction methods involving organic solvent extraction, Soxhlet extraction, steam distillation extraction, as well as subcritical extraction method and supercritical fluid extraction method were used to extract the celery seed oil. The contents of 3-n-butylphthalide and total phthalocyanine lactones were respectively detected by high performance liquid chromatography(HPLC) and ultraviolet visible spectrophotometry. Results The ranges of oil yield and the contents of 3-n-butylphthalide and total phthalocyanine lactones of celery seed oil extracted by different methods were 0.30%-20.02%, 1.40%-10.13%, 4.74%-17.65%, respectively, indicating obvious differences. Conclusion With R134a and butane as the solvents, the subcritical extraction method is better than other extraction methods for the extraction of 3-n-butylphthalide. With dimethyl ether as the solvent, the subcritical extraction method is the best for the extraction of total phthalocyanine lactones.
