Extractable Substances from Needles of Siberian Fir Picea obovata

The chemical composition of evergreen needles has been well studied [1, 2, 3, 4, 5]. Recently interest in the isolation from needles of polyprenols with several valuable properties has risen. New procedures for isolating low-molecular-weight components from evergreen needles have recently appeared [6, 7]. However, there is little published data on the composition of extractable substances from needles of Siberian fir, one of the forest species of Siberia .
We have previously reported on the composition of extractable substances from bark of Siberian fir growing in Altai and Novisibirsk District and monoterpenes of Siberian evergreens [9, 10, 11]. Herein we report on the composition of the extract of needles from the Siberian fir Picea obovata Ledeb. collected in January in Novosibirsk District.
Air-dried needles (250 g) were ground and extracted with methyl-t-butylether. The yield of ether extractable substances was 12.6 g (5.0 mass % of raw material).
Treatment of the extract with...
