Myroxylon balsamum (L.) Harms var. pereirae (Royle) Harms - Myroxylon pereirae (Royle) Klotzsch - Fabaceae
Balsam of Peru, Perubalsam-Baum
Evergreen tree, native to Central America (Mexico to Costa Rica), cultivated Java, Sri Lanka;
„Balsam of Peru smells of vanilla and cinnamon because it contains 60-70% cinnamein (a combination of cinnamic acid, cinnamyl cinnamate, benzyl benzoate, benzoic acid and vanillin). The other 30-40% contains resins of unknown composition. It also contains essential oils similar to those in citrus fruit peel. These are all potential allergens… Typical allergic contact dermatitis reactions may occur in individuals allergic to Balsam of Peru or any other chemically related substances. Flare-up of hand eczema is common in sensitive individuals if they use or consume products containing Balsam of Peru or related allergens. Oral exposure may cause sore mouth (tongue) and rash of the lips or angles of the mouth. “

„Balsam of Peru is used worldwide for different purposes. Three quarters of its constituents are still unknown, and its main allergens have not been identified to date… Using different analytic methods such as thin-layer chromatography, high-pressure liquid chromatography, gas chromatography/mass spectrometry, and sensitization experiments in guinea pigs resulted in the identification of a greater number of constituents and the determination of their sensitizing potency.
Benzyl isoferulate, coniferyl cinnamate, hydroconiferyl cinnamate, and hydroconiferyl benzoate were identified among others as new constituents. Also, the presence of coniferyl benzoate could be shown for the first time. It showed the strongest sensitizing capacity of all compounds tested followed by benzyl isoferulate. The latter is a significant cross-linking allergen because it occurs in propolis as well.“

Volatile constituents were identified by SPME/GC-MS analysis of Peru Balsam. A high percentage of nerolidol (38%) was found, together with benzyl benzoate (31%). Major components were also benzyl alcohol (8%), benzoic acid (6%), benzaldehyde, β-farnesene, α-farnesene, and styrene.
SFE CO2 extracts were rich in benzyl benzoate (48-60%), followed by benzyl cinnamate (15-37%) and nerolidol (7-17%).
Major products of hydro distillation were nerolidol (46%) and benzyl benzoate (44%); minor components were benzyl cinnamate (1%) and ethyl benzoate (1%).
