Abstract

The essential oil from the leaves and twigs of the Podocarpus pilgeri was collected in Xuan Nha Nature Reserve, Van Ho, Son La province was obtained by steam distillation. The yield of essential oil from the leaves and twigs was 0.057% and 0.073% in term of air-dry material. Essential oil are pale yellow and lighter than water. By using GC/MS analysis, there were 38 constituents from leaves were identified accounted for 99.87% of essential oil by weight. The main constituents were α-pine (32.83%), β-caryophyllene (8.40%), dolabradiene (10.96%), 16-kaurene (19.94%). Similarly, 47 constituents from twigs were identified and accounting 98.27% of essential oil. The main constituents of the essential from twigs were α-pinen (56.37%), β-caryophyllene (5.80%), dolabradiene (4.26%), α-copaene (3.86%). Research results on chemical composition of leaves and branches of short-leaf pine essential oil were first published in Vietnam.
