In this study, we aim to compare essential oils from Anethum graveolens L. obtained by hydrodistillation, steam distillation and supercritical fluid extraction. The influence of the particle diameter was investigated for all extraction techniques considered. The effect of pressure on the supercritical fluid extraction was also evaluated. For this, a full factorial design 2² combined with response surface methodology was used to maximize the yield of volatile extract from the seeds of A. graveolens L. The mathematical modeling of each extraction method was performed using a suitable model. The gas chromatography analysis (GC) identified dillapiole, carvone and its isomers to be the major compounds.

评价不同提取工艺对重生炭疽病种子的理化处理作用

在这项研究中,我们的目的是比较通过加氢蒸馏,蒸汽蒸馏和超临界流体萃取获得的来自香叶草的精油。对于所有考虑的萃取技术,均研究了粒径的影响。还评估了压力对超临界流体萃取的影响。为此,采用全因子设计2²结合响应面方法,以最大限度地提高重瓣草种子的挥发物提取量每种提取方法的数学模型均使用合适的模型进行。气相色谱分析(GC)确定了莳萝螺酮,香芹酮及其异构体为主要化合物。
