Antifungal activity of the essential oils from some species of the genus Pinus.
The chemical composition of the essential oils from the needles of Pinus ponderosa (north american pine), P. resinosa (red pine) and P. strobus (eastern white pine) has been determined by GC/MS (FID). The essential oils from P. resinosa and P. ponderosa in comparison to P. strobus have been characterized by the higher content of beta-pinene (42.4%, 45.7% and 7.9% respectively). On the other hand, a-pinene (17.7%) and germacrene D (12.2%) were dominant compounds of P strobus. Moreover the essential oil from P. resinosa was more rich in myrcene-15.9%. Estragole and delta-3-carene, each one in amount ca 8% were identified only in P. ponderosa. The content of essential oils in the needles slightly varied--0.65%--P. resinosa, 0.4%--P strobus, 0.3%--P. ponderosa. The antifungal activity has been investigated towards Fusarium culmorum, F solani and F. poae. The strongest activity was observed for the essential oil from P. ponderosa, which fully inhibited the growth of fungi at the following concentrations--F. culmorum, F. solani at 2% and F. poae at 5%.
