Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological properties. This review describes the isoflavonoids and biological activities from the tribe Dalbergieae (Fabaceae-Papilionoideae) species, in the period of 1945 to 2019. A total of 240 isoflavonoids were found in 69 species and in 15 genera. Formononetin, biochanin A and medicarpin were the most frequent isoflavonoids in this tribe. Dalbergia, Machaerium, Andira and Pterocarpus genera had a high number of species with occurrence of isoflavonoids. A total of 81 isoflavanoids and 46 species showed biological activities. This suggests that more works are necessary to evaluate the potential of this tribe. The present study contributes to the taxonomic classification of genus or species in the family, subfamily or tribe, once the correlation between secondary metabolites and morphological data is an important tool for the classification, phylogeny and evolution of species. This compilation also contributes to extend and update the researched period on the occurrence of isoflavonoids in species of the tribe Dalbergieae, described in the literature in other bibliographic reviews.
