Essential oils from the buds of Magnolia salicifolia, M. kobus, and M. kobus var, borealis. and of Chinese and domestic crude drug, Xin-yi, the dried buds of Magnolia were analyzed by thin-layer chromatography, infrared absorption spectra, and gas chromatography. 1) The essential oil of M. salicifolia has a more complex composition than that of M. kobus, and contains a large quantity of aromatic compounds such as safrol, methyleugenol, and trans-asaron. The essential oil of M. kobus consists of terpene compounds such as limonene, cineol, and camphor. 2) Chemo-types differing in the main components of essential oil were found in three individuals of M. salicifolia and two of M. kobus. Both indicated distinct geographical distribution.
