From the fruits of specimen of Enterolobium contortisiliquum Fabaceae, ten known compounds were isolated, namely seven triterpenes, maslinic acid (1), betulinic acid (2), 3-oxo-β-amyrin (3), ursolic acid (4 , β-amyrin (5), lupeol (6) and squalene (7); one steroid, ergosterol peroxide (8); one caffeic acid derivative, ethyl caffeate (9) and the ficaprenol-12 (10). This is the first reported occurrence of triterpenes 1-4 and 7, steroid 8 and ficaprenol-12 in the genus Enterolobium. The structures of the isolated compounds were determined on the basis of their spectral data.

“…This tree has been removed from natural areas owing to the advance of cattle grazing and agriculture in Brazilian SDTFs due to its poisonous fruits. The ingestion of E. contortisiliquum pods is harmful to cattle, causing photosensitivity reactions and spontaneous abortion (Bonel-Raposo et al, 2008;Costa et al, 2009). As a result many farmers have cut these trees near their ranches as fruiting of E. contortisiliquum occurs during the dry season and coincides with low forage availability.…”

a b s t r a c tFragmentation of tropical forests is one of the major threats to biodiversity and viable natural populations. Brazilian seasonally dry tropical forests (SDTF) are endangered because of human occupation, conversion of lands to agriculture and high deforestation rates in these fertile soils. Enterolobium contortisiliquum has been removed from SDTF natural areas due to the advance of cattle grazing and agriculture in Brazilian SDTFs. To aid conservation efforts of this species we used molecular markers to study the genetic diversity and population structure of E. contortisiliquum in Brazilian SDTF remnants. A total of 263 individuals in 13 forest patches were analyzed with 103 ISSR fragments. In spite of being found scattered among the SDTF patches, E. contortisiliquum populations exhibited high genetic diversity (mean Shannon's index of diversity = 0.384; mean genetic diversity = 0.280) and genetic divergence between populations was detected (˚S T = 0.155, p < 0.0001). UPGMA dendrogram, principal coordinate analysis and Bayesian analysis showed that E. contortisiliquum populations were clustered into three groups that were not related to geographic distance (r = 0.119, p = 0.197). However, these populations are spatially structured into groups distributed in the West, Central and East of the study area. This genetic structure may be related with landscape and both the Espinhaç o Range and São Francisco River may act as a partial geographic barrier limiting the gene flow. Because the highest rates of genetic diversity were found outside of conservation units, we propose the creation of protected areas in different geographic regions that include E. contortisiliquum populations from different genetic clusters.

“…Morong (Leguminosae) is a poisonous tropical tree species that has been removed from natural areas owing to the advance of cattle production and agriculture in central Brazil. The ingestion of E. contortisiliquum pods is harmful to cattle, causing abortion and severe injuries in the skin, mainly in photosensitive places without pigmentation (Bonel-Raposo et al, 2008;Costa et al, 2009). Therefore, many farmers have cut trees of this species near their ranches because the fruiting period of E. contortisiliquum occurs during the dry season, coincident with low forage availability.…”
