Abstract

Elionurus hensii is a plant belonging to the Poaceae family, widely used in food and traditional medicine as a tea drink. It strengthens the immune system, fights coughs, and alleviates joint pain. Due to the therapeutic and nutritional interest of its Essential Oil, the question of its production in terms of extraction yield arose. This work aimed to model the kinetic extraction of essential oil from the plant Elionurus hensii K. SCHUM from Congo in order to optimize its yield and develop the most suitable technologies for producing its essential oil at higher contents. In this study, the extractions were carried out by hydrodistillation on the roots (continuous extraction) and stem-leaves (continuous and discontinuous extraction) of the plant at different times corresponding to 15, 30, 45, 60, 90, 120, 150, 180, 210 and 240 minutes. The extraction results gave maximum contents of 1.81% on the roots and 2.7% on the stem-leaves for an extraction time of 180 min. The modified Monod models and the pseudo-diffusional Mafarat and Bélliard model showed a good fit with the experimental data. The values of R2 are such that R2 = 0.995 for roots and R2 = 0.9922-0.9928; 0.9726-0.978 for stem-leaflets respectively for the modified Monod models and the pseudo-diffusional Mafarat and Bélliard model. These two models were therefore found to be the best suited for the extraction kinetics of essential oil from the Elionurus hensii plant.
