“…On the other hand, Bocageopsis and Onychopetalum comprise few species, four and two, respectively (B. mattogrossensis, B. canescens, B. multiflora and B. pleiosperma, O. amazonicum and O. periquino) (Maas et al, 2007). Unonopsis is also the most explored from the chemical and biological viewpoints (Siqueira et al, 1998;Waechter et al, 1999;Silva et al, 2012bSilva et al, ,c, 2014. The chemical information regarding the Bocageopsis and Onychopetalum genera is still limited, being focused directed to the study of the essential oils and alkaloid compositions (Almeida et al, 1976;Oliveira et al, 2014;Soares et al, 2015).…”
