QUERT ALVAREZ, Rolando et al. Rendimiento de aceite esencial en Pinus caribaea MorElet según el secado al sol y a la sombra. III. Rev Cubana Farm [online]. 2001, vol.35, n.1, pp. 47-50. ISSN 1561-2988.

The results obtained in the determination of the yield of the essential oil from Pinus caribaea Moralet (male pine) according to the conditions and time of exposure to the sun and to the shade of the foliage of this Cuban endemic species are presented. Trees of 30 years old located in the areas of the Experimental Forestal Station of Viñales, Pinar del Río province, were used in the study. The size of the sample was of 3 trees and the time of distillation for the extraction of the essential oil was of 3 hours. Specimens of the foliage were taken at intervals of 1, 3, 6, 10 and 20 days. The results obtained showed that the foliage exposed to the shade has a higher percentage of essential oil that the foliage exposed to the sun, and that the time of exposure to the sun influences significantly on the yield starting from the third day on, whereas in the foliage exposed to the shade the differences are remarkable from the sixth day on.
