This study aimed to evaluate the leishmanicidal activity of ethanol extract, fractions, and isolated substance from Handroanthus serratifolius against Leishmania amazonensis. Furthermore, this activity was related to cytotoxicity, and the selectivity index was determined. The ethanol extract was obtained by maceration of the stem powder, and the extract was subjected to fractionation on chromat...

Adenocalymma bracteatum is a shrub of dense foliage and yellow flowers, easily found on grasslands areas in Central Brazil. The aim of this study was to determine the reproductive biology and the flower visitors of A. bracteatum in a pasture area nearby Ivinhema city, MS (Brazil). The flowering peak occurs in winter. The flower reflects ultraviolet light. Anthesis begins at 6:30h, and pollen an...

Oroxylum indicum (L.) Kurz a well know and pharmaceutically explored medicinal plant of the family Bignoniaceae but in context cytological work, meagre information is available on same plant. During present investigation six accessions O. were studied for understanding male meiosis related events using standard techniques. Although, meiotic course was found to be regular, anomalies such as chro...

Handroanthus serratifolius produces flowers during the dry season in the Cerrado biome, and it may be an important food source to some bird species. For Psittacidae species, like Forpus xanthopterygius, flowers are important in their diet. This study intended to characterize the behavior of F.xanthopterygius and evaluate the damage to the flowering and in the reproduction of H. serratifolius. F...

PREMISE OF THE STUDY Crescentia cujete (Bignoniaceae) fruit rinds are traditionally used for storage vessels and handicrafts. We assembled its chloroplast genome and identified single-nucleotide polymorphisms (SNPs). METHODS AND RESULTS Using a genome skimming approach, the whole chloroplast of C. cujete was assembled using 3,106,928 sequence reads of 150 bp. The chloroplast is 154,662 bp in ...
