A response surface method (RSM)was used to optimize supercritical CO2 extraction (SCE)of the extracts from Chinese Torreya aril and the main components of aril extracts was analyzed by gas chromatograph -mass spectrometer (GC -MS).Based on the single factor experiments,the dynamic extraction time,extraction tempera-ture and extraction pressure were selected as variables.The extraction yield of Chinese Torreya aril was regarded as index and the three -factor and three -level experiment was conducted by Box -Behnke experiment design method. The optimization process of extracts of Chinese Torreya aril by supercritical CO2 extraction was particle size of 40 mush,extraction time of 20 min,dynamic time of 2.5 h,temperature of 45 ℃ and pressure of 34 MPa.The optimal yield (22.12 ±0.09%)was obtained at the operating conditions.The results of GC -MS analysis showed that the main complements of aril extracts were diterpenoids,fatty acid,followed by sesquiterpenoids and monoterpenoids.
