-"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 leaf oil from South and Central California was very high in β-pinene (62-66%)estragol (6-20%), α-pinene (11-12%), and myrcene (4-7%) but low in car-3-ene (0.2-7%). \\+"The composition of the essential oil from the leaves of photochemical air pollution injured and healthy Pinus ponderosa trees was determined.
