- Abstract
- The aim of this paper is to analysis the volatile constituents in rhizome zingibers (RZ), zingiber officinale roscoe (ZOR) and ginger pee (GP).The similarities and differences of volatile components in RZ, ZOR and GP were investigated by GC-MS combined with a chemometric method named heuristic evolving latent projections (HELP). And temperature-programmed retention indices (PTRIs) were used together with mass spectra for identification of the essential oil components. In total, 85, 81 and 80 volatile components in volatile oil of RZ, ZOR and GP were separately determined qualitatively，accounting for 81.43%, 86.38% and 84.79% of total contents of volatile oil in RZ, ZOR and GP respectively. The results indicate that there were total 58 common compounds existing in RZ and ZOR, 63 common components between RZ and GP, 60 common components between ZOR and GP, and 52 common components existing among the three systems. The results obtained may be helpful to the further study of pharmacological activity for their potential utilization as therapeutical agents.
