Chemical composition of the oleoresin ofLarix kamtschatica

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 -element, longifolene, and germacrene D predominated. The main oxygen-containing diterpenoid was larixyl acetate. Seven resin acids were determined, the main one being isopimaric and palustric and/or levopimaric.Novosibirsk Institute of Organic Chemistry, Siberian Branch, Academy of Sciences of the USSR.

Neutral substances of the oleoresin ofAbies sibirca

Conclusions From the oleoresin ofAbies sibirica Ledeb. have been isolated manoyl oxide and a new diterpene alcohol with the composition C₂₀ H₃₄ O (I) which we have called neoabienol. It has been established that it is labd-11,13-dien-8-ol.Khimiya Prirodnykh Soedinenii, Vol. 5, No. 4, pp. 247–251, 1969
