Phytochemicals 

Machaerium multiflorum contains Machaeriols such as Machaeriol A and Machaeridols such as Machaeridol A which are hexahydrodibenzopyrans structurally related to Tetrahydrocannabinol and Hexahydrocannabinol with bibenzyl and benzofuran tailchains instead of pentyl. These compounds have been studied for their antibiotic and ant parasitic activity. It's been implicated that other Machaerium species may contain similar compounds.
