Open publisher page 0 citations

Abstract

Sample of bark of Toona sinensis was extracted with ethanol and purified by passing through silica gel column.The fat-soluble components in the eluant were separated and identified by GC-MS,and their relative contents(in %) were found by the method of normalization.Totally 41 compounds were identified and determined,amounting to 91.99% of the total peak areas of the fat-soluble components.The main compounds found with their relative contents were as follows: terpenoids(36.58%),alkanes(31.70%) and fatty acid(21.95%).
