Abstract

Eight substances have been isolated by preparative chromatography on silica gel from the essential oil ofLedum palustre L., collected in the Kostroma oblast in August. Six of them have been described previously for this essential oil (myrcene, palustrol, ledol, allocaromadendrene, 6-methyl-2-methyleneocta-5,7-dien-3-ol, and cyclocolorenone) and two are new substances not described in the literature: a colorless liquid with a pleasant smell having the composition C10H14O2, mp 108–111°C/4 mm Hg, n D 20 1.4925, d 20 20 1.002, [α]D±0°C, which has been called lepalol, and a colorless liquid with a pleasant smell having the composition C10H12O, bp 91–93°C/4 mm Hg, n D 20 1.5175, d 20 20 0.9444, [α]D±0°C, which have been proposed for lepalin and lepalol on the basis of their IR, UV, and NMR spectra. The physical constants of all the substances isolated and the characteristics of their IR, NMR, and mass spectra are given.
