Fava D'anta (Dimorphandra mollis Benth) is a native plant of the Brazilian open pasture used in the extraction of the active principles rutin, quercetin and ramnose, products used in the pharmaceutical and cosmetic industries. The exploitation of the fava d'anta for the extraction of these principles has been carried out through predatory exploration, and the study of the genetic variability could be important to provide strategies of conservation and maintenance of the species. The objective of this work was to analyze the genetic diversity of this species by means of the RAPD technique. Young fava d'anta leaves were harvested in seven localities (Januária, Patis, Mirabela, Lontra, CAA, Jequitaí and Morro Alto) in northern Minas; 43 primers were tested to analyze genetic diversity. The analysis of molecular variance (AMOVA) showed that 10.3% and 89.7% of the genetic variation was distributed among and within populations, respectively. Genetic diversity (Ĥe) ranged from 0.1736 (Morro Alto) to 0.2867 (Mirabela). Genetic analysis allowed the construction of a dendrogram with distinct groups. The information obtained could be used in the construction of a germplasm bank to contribute for the preservation of the species.
