Chemical composition of <Emphasis Type="Italic">Pinus silvestris</Emphasis> essential oil from contaminated areas

The chemical composition of Pinus silvestris essential oil from contaminated areas was studied. An apparent effect of radionuclides and toxic elements on the biosynthesis of terpenoids in common pine essential oil was found. Increasing contamination apparently increased the content of sesquiterpenes and O-containing substances and decreased the content of monoterpenes in the essential oil. The contents of α-pinene, camphene, and limonene increased and those of 3-carene, terpinolene, and β-pinene decreased in the monoterpene fraction. __________ Translated from Khimiya Prirodnykh Soedinenii, No. 1, pp. 47–49, January–February, 2007.
