Abstract


Thyme, Thymus vulgaris L., is an herb widely used throughout the world. It is, without doubt, one of the most popular plants in Morocco. For the purpose of examining the factors affecting the extraction of the essential oil of this plant by hydrodistillation, a screening study by Hadamard matrix type Placket and Burman was conducted. After an appropriate choice of six factors, sixteen experiments lead to a mathematical model of first degree connecting the response function (yield) to factors. Later than the realization of the experiments and data analysis, we concluded that five factors have a significant effect on the hydrodistillation process, namely: the extracting time, the harvest period, the individuality effect, the mass plant/water ratio and the temperature of heating. As for the drying of plant material, it presents a statistically negligible effect.

Author Keywords: Thymus vulgaris L., hydrodistillation, factors, screening, Plackett and Burman design, yield.


Abstract: (french)


Le thym, Thymus vulgaris L., est une herbe médicinale largement utilisée à travers le monde. Elle est, sans doute, l'une des plantes les plus populaires au Maroc. Dans le but du criblage des facteurs qui influent sur l'opération d'extraction de l'huile essentielle de cette plante, une étude de criblage par matrice d'adamard de type Placket et Burman a été menée. Après un choix approprié de six facteurs, 16 expériences ont conduit à un modèle mathématique du premier degré reliant la fonction de réponse (rendement) aux facteurs. Après la réalisation des expériences et l'analyse des données, nous avons conclu que cinq facteurs ont un effet significatif sur le procédé d'hydrodistillation, à savoir: le temps de traitement, la période de récolte, l'effet d'individualité, le rapport matière végétale/Eau et la température de chauffage. Quant au séchage des feuilles, il présente un effet statistiquement négligeable.

Author Keywords: Thymus vulgaris L., hydrodistillation, facteurs, criblage, plan Plackett et Burman, rendement.
