Objective:To study on extraction process of volatile oil from dried ginger and its inclusive compound by β-cyclodextrin（β-CD） from Sini effervescent tablet.Method:Orthogonal test was employed to investigate effect of water volume

soak time and distilled time on extraction of volatile oil;and took comparative test of saturated water solution method

colloid mill method

and ultrasound method

choose optimum inclusion method with inclusion efficiency of volatile oil

yield of inclusion and the content of oil in inclusion as comprehensive indexes;Optimum inclusion technology of colloid mill method was optimized by orthogonal test

and validate inclusion compound.Result:Optimum extraction technology conditions were to add 6 times the amount of water

and distilled 8 h without soaking;Optimum inclusion technology of colloid mill method was as follows:proportion of volatile oil to β-CD was 1∶8（mL∶g）

inclusion time was 45 min;the amount of water was 80 mL.Conclusion:Inclusion technology（colloid mill method）of volatile oil from dried ginger was simple

feasible and appropriated for large-scale production.
