Larix decidua Mill. - Pinaceae - European larch, Europäische Lärche

The terpene content of the resin from L.decidua was found to be very similar to that of L.leptolepis (Larix kaempferi, Japanese larch). α-pinene dominates with over 80%, and small amounts of β-pinene, camphene, myrcene and limonene are present, but δ-3-carene absent in both species.

By far the main component of the volatile fraction of the oleoresin from L.decidua was α-pinene.

Freshly exuded resin of L.decidua contains some amounts of epimanool and larixyl acetate.
These compounds do not survive ageing, so they cannot be used as markers of Venice turpentine, which is used in works of art.
