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.

"...the Massoia tree well-known for its fragrant bark, reminescent of coconut and biscuit... also used to produce the commercial Massoia oil applied in smaller amounts in aromatherapy and also as a flavoring material. Of special importance for the odors both of fresh bark and the essential oil are the two main components dec-2-en-5-olide (so-called 'Massoia lactone') and dodec-2-en-5-olide." \\ | "...the Massoia tree well-known for its fragrant bark, reminescent of coconut and biscuit... also used to produce the commercial Massoia oil applied in smaller amounts in aromatherapy and also as a flavoring material.

"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.
