本文综述了在实验室中对七种芳香植物挥发油进行超临界流体萃取（SFE）的研究，这些植物包括：薄荷（Mentha pulegium L.）、茴香种子（Foeniculum vulgare Mill.）、香菜（Coriandrum sativum L.）、香菜（Satureja fruticosa b<s:1> guinot）、冬季香菜（Satureja montana L.）、棉花薰衣草（Santolina chamaecyparisus）和百里香（thyymus vulgaris）。一个流动装置与1升萃取器和两个0.27升分离器建立进行研究的温度范围从298至353 K和压力高达30.0兆帕。对提取和分馏的最佳实验条件进行了优选，得到了与加氢蒸馏（HD）相比收率和组成的最佳折衷。HD油和SFE油之间的主要区别是表皮蜡的比例很小，而百里香醌的含量相对较高，百里香醌是一种具有重要生物学特性的氧化单萜烯，存在于百里香和冬季咸味油中。另一方面，用sovov<e:1>的模型讨论了超临界提取挥发油数据的建模问题。这些模型已成功地应用于其他挥发油提取。此外，还提到了在我们实验室进行的其他涉及超临界CO2的实验研究。
An overview of the studies carried out in our laboratories on supercritical fluid extraction (SFE) of volatile oils from seven aromatic plants: pennyroyal (Mentha pulegium L.), fennel seeds (Foeniculum vulgare Mill.), coriander (Coriandrum sativum L.), savory (Satureja fruticosa Béguinot), winter savory (Satureja montana L.), cotton lavender (Santolina chamaecyparisus) and thyme (Thymus vulgaris), is presented. A flow apparatus with a 1 L extractor and two 0.27 L separators was built to perform studies at temperatures ranging from 298 to 353 K and pressures up to 30.0 MPa. The best compromise between yield and composition compared with hydrodistillation (HD) was achieved selecting the optimum experimental conditions of extraction and fractionation. The major differences between HD and SFE oils is the presence of a small percentage of cuticular waxes and the relative amount of thymoquinone, an oxygenated monoterpene with important biological properties, which is present in the oils from thyme and winter savory. On the other hand, the modeling of our data on supercritical extraction of volatile oil from pennyroyal is discussed using Sovová’s models. These models have been applied successfully to the other volatile oil extractions. Furthermore, other experimental studies involving supercritical CO2 carried out in our laboratories are also mentioned.
