Essential oils of the methylchavicol type Magnolia salicifolia MAXIM. were examined. The yields of oils were 0.78-1.06% of fresh shoots, 1.42% of fresh leaves, 0.51% of branchlets, 3.80% of fresh flower buds, and 0.92% of fresh flowers. The shoot oil contained 69.1-84.1% of methylchavicol and the leaf oil contained as high as 91.4% of methylchavicol, but the oil from branchlets contained 23.8% of 1,8-cineole, 19.7% of citral-b, and 30.2% of citral-a, and the oils from buds and flowers also contained 22.6-24.2% of citral-b and 38.1-43.3% of citral-a, as in the case of the anethole type, and the methylchavicol, safrole, and methylengenol type M. salicifolia. The oil of Magnolia kobus DC. examined by Asahina, et al. was not the oil of a true Magnolia kobus but was an oil of this methylchavicol type Magnolia salicifolia.
