The compositions of the essential oils obtained by steam distillation from the leaves of frost-resistant stocks of trifoliate orange (P. trifoliata (L.) Raf.) and Yunos-Yuzu citrus (Citrus ionos (Sieb.) and grafts of the mandarin orangeC. unshiu Marc —P. trifoliata +C. unshiu andC. ionos +C. unshiu — have been investigated with the aid of vacuum(More)
The composition of the essential oil was determined by gas--liquid chromatography on a Varian Aerograph 1860 instrument with a flame-ionization detector. The best separation of the essential oil was achieved in a 550 x 0.2 cm column containing 10% of FFAP on Chromosorb G AW-DMCS 80/100 mesh. The carrier gas was helium at a rate of flow of 40 ml/min.

The composition of the essential oil was determined by gas--liquid chromatography on a Varian Aerograph 1860 chromatograph using a flame-ionization detector. The best separation of the essential oil was achieved on a 550 × 0.2 cm column containing 10% of the stationary phase FFAP on Chromosorb G AW-DMCS 80/100 mesh. The carrier gas was helium at the rate of(More)
The high-boiling fraction, after saponification, was chromatographed on alumina (activity grade II-III) and the sesquiterpene hydrocarbons, carbonyl compounds, and alcohols were separated by successive elution with petroleum ether, benzene, and diethyl ether. The components were isolated from the fractions obtained on distillation and chromatography on(More)
The essential oils were distilled in vacuum into low-boiling and high-boiling fractions. The high-boiling fraction, after saponification, was chromatographed on AI203 (activity grade II-III), and by successive elution with petroleum ether and with ethanol the sesquiterpene hydrocarbons and the terpene alcohols were separated. Substances were isolated in the(More)
The terpenes were studied by gas-liquid chromatography under the following conditions: I) Khl-4 ahromatograph with a thermal conductivity detector using helium as the carrier gas with a column (2.4 m x 0.5 cm) containing the stationary phase polyethyleneglycol (mol. wt. 20,000) in an amount of 15% on the solid support Chromosorb W. The column temperature(More)
