Bursera microphylla—burseran (WA, KB), deoxypodophyllotoxin (LE, PS 154), and β-sitosterol (CA, LL, WA) were isolated by Cole from this species (Hartwell 1976).

“Four cytotoxic lignans were isolated from the stem bark of
Bursera permollis (Burseraceae), namely, deoxypodophyllotoxin (1),
beta-peltatin methyl ether (2), picro-beta-peltatin methyl ether (3), and
dehydro-beta-peltatin methyl ether (4). Also isolated was the inactive
lignan, nemerosin (5). Compounds 1 and 2 were potently cytotoxic when
evaluated against a panel of human cancer cell lines.”
