Classification of Aristolochia species based on GC-MS and chemometric analyses of essential oils.
Essential oils were obtained from roots of 10 Aristolochia species by hydrodistillation and analysed by GC-MS. A total of 75 compounds were identified in the analysed oils. Multivariate analyses of the chemical constituents of the roots enabled classification of the species into four morphological groups. These forms of analysis represent an aid in identification of further specimens belonging to these species.
