Abstract
The volatile composition of leaves from 14 populations of Hippophae rhamnoides ssp. yunnanensis and H. rhamnoides ssp. sinensis growing in China was analyzed by gas chromatograph¨Cmass spectrometer (GC¨CMS). Of the 44 compounds represented, 40 were identified. Principal component analysis and cluster analysis were used to investigate the inter-population variability in the composition of volatile compounds. Two main chemotypes were identified, one rich in hexadecanoic acid and eicosanol and the other rich in tetracosane. The hexadecanoic acid and eicosanol-rich chemotype characterizes all seven populations of H. rhamnoides ssp. yunnanensis sampled and the tetracosane-rich chemotype all seven populations of H. rhamnoides ssp. sinensis.
