- | "The composition of the essential oil from the leaves of photochemical air pollution injured and healthy Pinus ponderosa trees was determined. Methyl chavicol, a product of the carbohydrate-shikimic acid metabolism, was strikingly lower in the injured trees. However, no significant differences were observed in the monoterpenoids." | ||

- | "The composition of the volatile leaf oil of Pinus ponderosa Dougl. Ex. P. Lawson was re-examined by fused silica capillary gas chromatography-ion trap mass spectroscopy. The leaf oil from Washington was high in α-and β-pinenes (9.1% and 37.9%), car-3-ene (19.3%), α-terpineol (6.2%), myrcene (4.1%) and terpinolene (3.1%). A total of 52 components were identified. This analysis is compared and contrasted with the previous analyses which reported from 8 to 17 monoterpenoids plus estragole in Ponderosa pine leaf oil." \\ | ||
