| chemical composition and in vitro antimicrobial activities of the essential oils from endemic psiadia species growing in mauritius. | the composition of the leaf oils, obtained by hydrodistillation, of five endemic psiadia species of the asteraceae family were studied by gc/ms on both polar and non-polar columns. the analysis showed that the volatile components of the oils were made up essentially of monoterpenes, sesquiterpenes, aliphatics and other shikimic acid derivatives. with respect to the non-volatile components, great variations were observed: p. lithospermifolia contained (e)-isoasarone (51.5%); p. penninervia: eugen ... | 2004 | 15516729 |
