Investigation of the Main Chemical Compounds in Pyrethrum Extract Obtained by Supercritical Fluid Extraction

Abstract:

The main chemical compounds in pyrethrum flower extract obtained by supercritical fluid extraction (SFE) were identified by GC-MS. Peak area normalization was used to determine relative percentage content of the compounds. The results showed that the main chemical compounds in pyrethrum flower extract were β-farnesene, β-cubebene, ethyl palmitate and ethyl linoleate, besides six pesticidal active compounds of pyrethrins that were cinerin I, jasmin I, pyrethrin I, cinerinII, jasminIIand pyrethrinII.
