摘要：Os constituintes voláteis obtidos dos extratos pentânicos das flores de Encyclia vespa e E. fragrans através de destilação-extração simultânea foram analisados por CG/EM. Os principais componentes voláteis identificados nas flores de E. vespa foram terpinen-4-ol (20,3%), verbenona (14,8%), trans-verbenol (13,6%) e a-pineno (11,8%). Os principais voláteis das flores de E. fragrans foram terpinen-4-ol (18,3%), (2Z,6E)-farnesol (15,4%) e trans-verbenol (10,2%).
其他摘要：The volatile constituents obtained from the pentane extract, using simultaneous distillation-extraction of the flowers of Encyclia vespa and E. fragrans were analysed by GC/ MS. The main volatile components identified in the flowers of E. vespa were terpinen-4-ol (20.3%), verbenone (14.8%), trans-verbenol (13.6%) and x-pinene (11.8%). The major volatiles of the flowers of E. fragrans were terpinen-4-ol (18.3%), (2Z,6E)-farnesol (15.4%) and trans-verbenol (10.2%).
