[Method] GEO was extracted from ginger roots by supercritical fluid extraction （SFE） method. The effects of flow rate of CO2, mesh size of ginger powder and volume of entrainer were investigated by single-factor experiments and response surface method. The content and extraction rate of 6-gingerol represented the extraction index of GEO. [Result] The conditions were optimized as follows： flow rate of CO2 at 25 L/h, mesh size of ginger power of 80 mesh, and volume of anhydrous ethanol as entrainer of 92.46 ml. The optimal extraction rate of 6-gingerol was 3.21%, which was predicted by RSM. [Conclusion] The optimal process of supercritical carbon dioxide extraction of ginger essential oil was identified by singlefactor experiments and response surface method. The present study provides a satisfactory method for purifying GEO from ginger for industrial purpose.展开更多

The effects of the extraction pressure, temperature, CO2 flow rate and particle size of raw material on the extraction rate are investigated, and the optimum process conditions of supercritical CO2 extraction are determined. A mathematical simulation model is established based on the mass conservation in differential units of extraction bed. The total mass transfer driving force and the equilibrium absorption constant are evaluated by the linear driving force theory. The results from numerical simulation agree well with the experimental data.展开更多

From 3 till 13 weeks, birds in group 1 (control) received distilled water orally (100 μl/kg body weight), while the other three test groups during the same period, received respectively by gavage 50, 100 and 150 μl of ginger roots essential oil per kg body weight. At 11 weeks old, eight birds per group in each treatment were randomly selected and slaughtered, blood samples collected for analysis. On the other hand, the remaining females were maintained 3 with one untreated male in identical boxes per treatment, for fertility assessment, eggs characteristics and hatchability traits. Throughout the experiment, biochemical parameters, eggs characteristics, fertility and hatchability traits were analyzed. No significant change (p > 0.05) was observed during the experimental period for body and relative ovary weights. Contrary, the relative uterus weight significantly increased (p < 0.05) in dose-dependent manner. The level of serum total proteins, LH, FSH and estradiol significantly increased (p < 0.05) in a dose-dependent manner. Also, fertility, hatchability of fertile eggs, total hatchability and chick’s weight significantly increased (p < 0.05) in birds received 100 and 150 μl/kg b.w compared to those of control group. On the other hand, embryonic mortality decreased significantly (p < 0.05) whatever the ginger rhizomes essential oil dose. It was concluded that ginger rhizomes essential oil enhances bird reproductive performances, proteins and reproductive hormone levels and hatchability traits in treated female quails.展开更多
