A method of sample preparation of standardized extracts of Ginkgo biloba using supercritical fluid extraction (SFE) is described. Ginkgolides and bilobalide could be selectively extracted with carbon dioxide containing 10 % methanol at 335 atm and 45 "C from a methanolic solution of the extract. An

Two-and three-factorial designs have been used to optimize the supercritical fluid acetylation-extraction of o-cresol, m-cresol and p-cresol in soil samples. Overall, nine variables (carbon dioxide flow rate, fluid density, extraction cell temperature, static extraction time, nozzle and trap tempera
