Abstract
In order to determine the composition of ginger and fresh ginger and efficacy differences, this study uses gas chromatography-mass spectrometry to identify the ginger and fresh ginger supercritical CO,sub>2 extract of the chemical composition and relative content. The results showed that the extraction rate of ginger and fresh ginger oleoresin is respectively 5.15±0.12% and 4.67±0.15%, the chemical composition of both contained basically the same, mainly zingiberene α-, β-half times the water Qinene, β-myrrhene, α-farnesene, α-curcumene, 6-gingerol, 6 zingiberene phenol and decomposition zingerone etc., but significant differences relative content. In the aroma of terpene compounds, ginger relative amount of the compound 1, 8-cineole, β- fragrant small chestnut, citral, geraniol, geranyl acetate and α-zingiberene other significant lower than fresh ginger and γ-Selinene and large myrcene D detected only in fresh ginger, ginger and the relative content of α-curcumene significantly higher than fresh ginger. The relative amounts of the total ginger gingerol compounds than fresh ginger high of 7.86%, in particular 6-and 10- zingiberene relative content of phenol phenol zingiberene high 15.49 and 30.51%, respectively, compared with fresh ginger.
