Essential oils of Magnolia denudata DESR. (Magnoliaceae) were examined in detail. The yields of oils were 0.03-0.05% in the fresh shoots (branchlets and leaves), 0.04-0.05% in the leaves, 0.29-0.67% in the flower buds, and 0.08-0.09% in the flower in full bloom. The main components of essential oils of the fresh leaves were β-caryophyllene and (+)-nerolidol, while those of the branchlets and barks were 1, 8-cineole, (+)-terpinen-4-ol, and (-)-α-terpineol, and that of the flower and flower buds was 1, 8-cineole.
