 Endemic tree of the island of New Guinea, optimal growth in rainforests between 400 m and 1000 m altitude. The aromatic bark from the tree has been an article of commerce for centuries, now as the source of massoia oil used in aromatherapy.  Endemic tree of the island of New Guinea, optimal growth in rainforests between 400 m and 1000 m altitude.

 "Exhaustive hydro-distillation of the bark, heartwood and fruits of Cryptocarya massoy (Lauraceae) afforded pale yellow-coloured oils in 0.7, 1.2 and 1.0 % yields, respectively. Detailed chemical evaluation of these distillates using GC/MS revealed the major components in the bark and the heartwood oils to be the C-10 (5,6-dihydro-6-pentyl-2H-pyran-2-one; bark 64%, heartwood 68%) and C-12 (5,6-dihydro-6-heptyl-2H-pyran-2-one; bark 17%, heartwood 27%) massoia lactones, while the major fruit oil constituent was benzyl benzoate (68.3 %). The heartwood also contained trace amounts of the C-14 (5,6-dihydro-6-nonyl-2H-pyran-2-one) massoia lactone (1.4 %) and the saturated C-10 derivative δ-decalactone (2.5 %)." \\ "Exhaustive hydro-distillation of the bark, heartwood and fruits of Cryptocarya massoy (Lauraceae) afforded pale yellow-coloured oils in 0.7, 1.2 and 1.0 % yields, respectively.
