Myroxylon balsamum (L.) Harms var. balsamum - syn.Toluifera balsamum L. - Fabaceae
Tolu balsam, Tolubalsambaum
Evergreen tree, native to northern South America (Venezuela to Peru); solidified resin bled from the trunk is called tolu balsam.
„The balsam has a sweet, pleasant and lasting aroma and is also considered to exhibit a certain fixative effect. It is commonly used as aingredient in confectionary products and cosmetics and as an additive to tobacco… The hexan-soluble fraction of an ethanolic solution of commercial tolu balsam, accounting for the most of the aroma, is shown to be a complex mixture, composed of aromatic and terpenoid compounds. Benzoic and cinnamic acid, the corresponding alcohols, aldehydes, ethyl, benzy, and cinnamyl esters, methyl cinnamate, styren, eugenol, vanillin, benzyl ferulate and isoferulate, ferulic acid, and 1,2-diphenylethane are the aromatic compounds identified.“
