Abstract
In this study, the extracted oil of Pistacia lentiscus L. the Tunis region was extracted using supercritical carbon dioxide (SC-CO2) extraction containing different major components in the oil such as α-pinene (32%) and terpinene-4-ol (13%). The investigation of the effect of different variables on the extraction yield with 5% level of confidence interval showed that the CO2 pressure was the main significant variable to influence the oil yield. In order to better understand the phenomena, three parameters were considered to adjust all parameters of broken and intact cell (BIC) model: grinding efficiency (G), the internal mass transfer parameter (), and the external mass transfer parameter (), which were estimated by experimental extraction curves to calculate the diffusion coefficient. From an economic point of view, we found out that the high cost of production of the extracted oil was due to the low mass of extracted oil obtained from this type of plant.
Highlights
Plant species with medicinal properties are becoming crucially essential in research due to their utilities in many areas such as traditional medicine, food, cosmetics and pharmaceuticals [1]
We aim to study the influence of operating parameters on mass transfer by evaluating a process applying the broken and intact cell (BIC) model proposed by Sovová [29] in 1994 which was simplified later by Stástova et al [30] on the essential oil extraction curves that are acquired from

Summary
Plant species with medicinal properties are becoming crucially essential in research due to their utilities in many areas such as traditional medicine, food, cosmetics and pharmaceuticals [1]. In Tunisia, a species of plant called Pistacia lentiscus L., commonly known as “Dharw” in the Maghreb and “Elustaka” in the Middle East, has medicinal properties in its oil extract. The major objective of the extraction process is to provide a more concentrated form of the desired material. The extraction effectiveness and the safety process must be priorities
