Abstract:
Supercritical CO2 extraction was mainly adopted to extract Torreya grandis episperm, and its chemical components of extractive were analyzed in this paper. Effects of extraction pressure, temperature, time and separation temperature single-factor tests on the yield of extractive were investigated. Suitable conditions were determined based on orthogonal experimental program, i. e., extraction pressure 15 MPa, extraction temperature 45℃, extraction time 120 min, separation temperature 35℃. Under this condition, the yield of extractive was 17.5%. By analyzing the extractive, it was found that there were 38 chemical compounds. The terpene compounds was the main content in the extractive of Torreya grandis by GC-MS.
