„The tree secretes a soft white resin called Phillipine elemi, from which is borne out in the air and used as incense.“
http://de.wikipedia.org/wiki/Canarium_luzonicum

„Aromatic elemi oil is steam distilled from the resin. It is a fragrant resin with a sharp pine and lemon-like scent… Elemi resin is chiefly used commercially in varnishes and lacquers, and certain printing inks. It is used as a herbal medicine to treat bronchitis, catarrh, extreme coughing, mature skin, scars, stress, and wounds.“

Manila elemi resin is constituted of tetra- and pentacyclic triterpenoids (70-80%) and essential oil (20-30%). An extract of the resin contained monoterpenes (30.8%) and sesquiterpenes (0.4%). Main monoterpenes were limonene (23.5%), α-phellandrene (4.2%), sabinene (0.7%), and γ-terpinene (0.5%). Main sesquiterpenes were elemol, β-eudesmol, and guaiol.

The essential oil of manila elemi contained limonene (54-56%), α-phellandrene (8-17%), elemol (6-13%), sabinene (3-5%), elemicin (2-4%), β-phellandrene (2%), α-terpinolene (2%), and α-terpineol (1-2%).

„Manila elemi oil, hydrodistilled from Manila elemi gum, was analysed by GC and GC-MS. Thirty-nine compounds constituting together 99.2% of the oil were identified, limonene being the most abundant (56%)… The other main components identified were α-phellandrene (17.6%), elemol (6.3%), sabinene (5.7%), α-terpinolene (2.8%), elemicin (2.4%), and β-phellandrene (2.3%). An interesting feature of this oil is the occurence of phellandrene dimers.
… oil kept in a colorless container …showed some significant changes. The relative percentages of limonene remained more or less the same… While the relative amounts of α-phellandrene and sabinene decreased almost by half, there was an approximately two-fold increase in the percentage amounts of elemol, elemicin, α-terpinolene and a number of minor compounds such as α-phellandrene dimer.“
