AbstractThe junipers of Cubaare Juniperus lucayanaandJ. Saxicola, the latter being endemic to Pico Turquino in Cuba. In this first report on the oils of the junipers of Cuba, the leaf oils were first extracted and then analysed by GC‐MS.Juniperus lucayanafrom mainland Cuba and the Isle of Pines had oil yields (oven dry weight basis) of 0.58% (2 h) and 2.33% (24 h), and 0.40%(2 h), and 1.58% (24 h), respectively. The oils are dominated by α‐pinene (25–27%), limonene (23–27%), sabinene (11–12%) with small amounts of sesquiterpenes. The volatile leaf oil ofJ. saxicolawas obtained in yields (oven dry weight basis) of 0.30% (2 h) and 0.72% (24 h). Its oil is dominated by sabinene (25%) and α‐pinene (24%), and is more similar toJ. lucayanathan other species of the Caribbean. The oil compositions of other junipers of the Caribbean are included to aid in makin
