内容記述 | The leaves of Citrus depressa Hayata (so called Hirami-Lemon or Shiikwasha, 70kg) collected at the central and the southern parts of Okinawa, were steam distilled,and the essential oil was obtained. The essential oil was then successively washed with 3 % sodium hydroxide, and water, which was evaporated off after drying over sodium sulfate, yielding a neutral material (about 290 g). The neutral essential oil, 30g, was chromatographed on an alumina column, and the substance eluted by petroleum ether was distilled and separated 5 fractions. The main components of Fr.1 and Fr.2 were known to be α-pinene and β-pinene,respectively, by the gas chromatography.Fr.3 and Fr.4 shown two main peaks in the gas chromatography could not be separated by the gas chromatography. But they must be hydrocarbon of monoterpenoids in view of infrared spectrum. boiling point, and elementary analysis.Found: C,88.94; H,10.83. Calcd. for C_10H_14 : C, 89.55; H, 10.45 % or for C_10H_16 : C,88.24; H, 11.76%. A small peak of Fr. 3 was identified as limonene. Fr. 5 and\nResidue were separated pure by the gas chromatography and identified as thymol methyl ether. Its infrared and ultraviolet spectrum were identical with that of the pure thymol methyl ether, and besides, it was ascertained by the NMR spectrum. Found: C, 79.93; H, 9.65. Calcd. for C_11H_16O: C, 80.45; H, 9.76 % The fraction eluted by ethyl ether on alumina column was identified as linalool. | |||||||||
