    In this study, the response surface methodology (RSM) was used to optimize the hydrodistillation process of Algerian Salvia officinalis essential oil. The effects of grain size, condensing flow rate and extraction time on oil yield were studied. A 3-factor design by the BoxBehnken method was used to produce factor combinations, from the response surface analysis. A second-order polynomial expression was deduced and used to determine the best yield efficiency of extracted oil according to the optimal conditions. Analysis of variance (ANOVA) indicates that the generated second-order polynomial model was highly significant with R2 = 0.9589 and P <0.006. Optimum oil yield conditions (0.98%) were estimated at a particle diameter of 2mm, a condensation flow rate of 1.4mL/min of and an extraction time of 210min. The essential oil extracted from the sage leaves by hydrodistillation was analyzed by GC/MS, to afford α.-Thujone, camphor, 1,8- cineole and β.-Thujone as main components.

    ECO-EXTRACTION PROCESS OF ESSENTIAL OIL OF THE VEGETAL SPECIES EUCALYPTUS CAMALDULENSIS DEHNH.: PARAMETRIC MODELING AND OPTIMIZATION BY BOX-BEHNKEN PLAN
    (Editura Academiei Romane/Publishing House of the Romanian Academy, 2023-10-23) ABIDI Abdenabi ,a,b,* ,a ,c d and; DJERMANE Mohamed; IEZID Mostepha; GHERRAF Noureddine; PONTIE Maxime
    This study was aimed to implement response surface methodology to optimize the hydrodistillation parameters of the essential oil of the plant species Eucalyptus camaldulensis (RSM). The distillation time, condensation flow rate, and particle size were the desired parameters. To generate factor combinations, a three-factor Box-Behnken design was used. The response surface analysis yielded a linear model, which was used to calculate the top yield of extracted oil based on the optimized conditions. ANOVA shows that the generated polynomial model was highly noteworthy, with R2=0.861. The peak yield was 0.513663% at the optimal conditions, which were 1 mm as particle size, 3.4 mL/min as condensation flow rate, and 210 min as extraction time. The GC/MS analysis revealed the presence of p-cymene (26.22%), spathulenol (16.71%), and 1.8-cineole (14.44%) as major components.
