Abstract
The essential oils obtained from flowers buds and seeds of Panax notoginseng (Burk.) F.H. Chen (Araliaceae) have been analyzed by GC (FID) and GC/MS. Thirty components of the oil of the flower buds, representing 93.6%, and sixteen components of the seeds oil, representing 96.5%, were identified, respectively. The main constituents were sesquiterpenes: spathulenol, germacrene D, bicyclogermacrene, and α-panasinsene. A comparison between constituents of the seed and flower bud oils with those reported in the literature for other Panax ssp. revealed some chemotaxonomical considerations.
