Samples collected from nature include the very dark brown to black resin of Guiacum officinale (Zygophyllaceae), known locally as guayacan, whose resin tends to be spherical, collected by M. Canals in Guanica (Puerto Rico) and the whitish, malleable, and the highly odorous resin of Dacryodes excelsa (Burser-aceae), known locally as tabonuco, collected by F. Wadsworth and one of the... 

Modem resin from Rfo Grande, Puerto Rico, identified as Dacryodes excelsa (family Burseraceae) and called tabonuco, gives spectra (Figure 5) that are identical in almost all details to the published spectra of the Burseraceae resin, probably of genus Bursera from Mexico (Figure 2 in ref. 6). This observation establishes the chemical identity of these two materials. As Burseraceae resins are triterpenoid (in contrast to diterpenoid Agathis and Hymenaea), we conclude that Dacryodes resin also is triterpenoid.
