Chemical constituents from Flourensia resinosa S.F. Blake (Asteraceae)

β-eudesmol (1), cryptomeridiol (2), ilicic acid (3), 5,7-dihydroxyflavone (chrysin, 4) and 7-O-methyl-chrysin (tectochrysin, 5) were isolated as the major constituents from the acetone extract of the aerial parts of Flourensia resinosa S.F. Blake (Asteraceae), along with flourensiadiol (6), spathulenol (7), p-acetophenol (8), lupeol (9), β-sitosterol (10), triacontanol (11) and squalene (12). Based on previous studies, this chemical composition for F. resinosa is in accordance with the chemical profile of other species of Flourensia. The profile of flavonoids, sesquiterpenes and benzofurans may have chemotaxonomic significance within this genus.
