We have studied the composition of the monoand sesquiterpenoids of the oleoresin of the Sakhalin spruce (Picea glehnii, Mast.) collected in 1974 in the Korsakov leskhoz [Forestry farm] (Sakhalin). After the working up of the oleoresin (1.75 kg), fractions of monoterpene hydrocarbons (137 g), monoterpene alcohols (8.4 g), sesquiterpene hydrocarbons (10.5 g),(More)
We have previously studied the monoand sesqulterpene hydrocarbons [i] and the diterpenoids and resin acids [2] of the oleoresin of Picea koraiensi8 Nakai (Korean spruce). Continuing our investigation of the oleoresin, we have determined the composition of the fraction of monoand sesquiterpenoids obtained by fractional distillation of the oxygen-contalning(More)
The terpenoid compositions of the oleoresins of the oriental spruce and of the Nordmann fir growing in the Caucasus have been studied. From the oleoresin ofPicea orientalis (L.) Link, which belongs to the sectionOmorica, 32 mono-, sesqui-, and diterpene compounds have been identified, and fromAbies nordmanniana Stev. 37 mono-, sesqui, and diterpene(More)
The monoterpenes (56 g) were analyzed by the GLC method. Seven compounds were identified from their relative retention times, ~-pinene(1.5%), B-pinene (1.7%), 3-carene (85.6%), myrcene (0.5%), B-phellandrene (4.7), limonene [1.0%), and 7-terpinene (1.4%). As in a botanically close species, the Kamchatkan larch, 3-carene predominated in this oleoresin, but a(More)

The chemical composition of the oleoresin of the Kamchatka larch has been studied. Mono-, sesqui-, and diterpenoids have been found in it. The monoterpenes were represented by nine components (the main one being 3-carene), and among the sesquiterpene hydrocarbons γ-element, longifolene, and germacrene D predominated. The main oxygen-containing diterpenoid(More)
Of sesquiterpene compounds we found in this oleoresin only (+)-cis-e-bisabolene, which we have detected previously in the oleoresin of Pinu8 pum~la Pall. Rgl. [3]. It must be mentioned that sesquiterpenes of the bisabolane series are not characteristic for spruce oleoresins and have been detected in other species only in trace amounts [3]. At the same time,(More)
In the systematics of Far Eastern species of larches there is a number of obscure questions, but the Korean Dahurian larch (Larix olgensi8 A. Henry) is recognized by all botanists as an individual species [I]. In the present paper we give information on the composition of the terpenoids of the oleoresin of the Korean Dahurian larch, a sample of which was(More)
