The essential oils from leaves, branches, roots and cones of the Keteleeria evelyniana was collected in Xuan Nha Nature Reserve, Moc Chau district, Son La province, Vietnam and was obtained by steam distilation and the yield of essential oils was 0.1%, 0.06%, 0.014% and 1.56% from air-dry material. By using GC/MS analysis, there are 42 constituents from leaves were identified and accounting 99.74% of essential oil. The main constituents were α-pinene (27.07%), β-pinene (17.85%), limonene (8.57%), β-caryophyllene (13.48%) and β-phellandrene (6.05%)
there are 42 constituents from branches were identified and accounting 98.67% of essential oil. The main constituents were α-pinene (16.85%), β-pinene (8.26%), limonene (16.29%), β-caryophyllene (25.18%), β-phellandrene (9.57%) and α-humulene (4.98%). There are 41 constituents from roots were identified and accounting 98.09% of essential oil. The main constituents were α-pinene (24.73%), β-caryophyllene (43.84%) and α-humulene (8.83%). There are 23 constituents from cones were identified and accounting 98.98% of essential oil. The main constituents were α-pinene (56.56%), β-pinene (21.73%), myrcene (6.82%) and germacrene D (4.06%). This is the first study on the chemical constituents of essential oils from the branchs, roots, and cones of Keteleeria evelyniana in Vietnam.Tinh dầu từ lá, cành, rễ và nón loài Du sam núi đất (Keteleeria evelyniana Mast.) thu mẫu tại khu bảo tồn thiên nhiên Xuân Nha, Mộc Châu, Sơn La, được chưng cất bằng phương pháp lôi cuốn hơi nước có hồi lưu.
