Background The search for substances with antimicrobial properties is intensifying every day, given the increasing number of microorganisms resistant to the usual antibiotics. The use of plant components in the pharmaceutical field has gradually increased in Brazil. According to the World Health Organization, medicinal plants should be the best sources to obtain up new varieties of drugs [1]. D...

Treatment of tuberculosis (TB) is a challenge because of multidrug-resistant and extremely drug-resistant strains of Mycobacterium tuberculosis. Plant species contain antimicrobial compounds that may lead to new anti-TB drugs. Previous screening of some tree species from the Anacardiaceae family revealed the presence of antimicrobial activity, justifying further investigations. Leaf extracts of...

Investigation into the initial developmental stages of a given structure is fundamental for precise characterization as well as for comparative analysis in relation to other taxa when homologies are established. For the Anacardiaceae family, investigations of the initial development of the pericarp or its basic histological sites, the epicarp, mesocarp and endocarp, are relevant since these reg...

Mangiferin, a C-glucopyranoside of 1, 3, 6, 7-tetrahydroxyxanthone, has been isolated from various parts of Mangifera indica (Anacardiaceae). The conclusive structure of mangiferin has been established by various researchers using a wide range of chemical and spectral analytical techniques. Mangiferin has been traditionally used in some parts of world as anti-inflammatory, analgesic, antipyreti...

The present paper is a continuation of a series of comprehensive taxonomic treatments of cercosporoid fungi (formerly Cercospora s. lat.), belonging to Mycosphaerellaceae (Ascomycota). This fifth contribution of this series proceeds with treatments of cercosporoid fungi on dicots and comprises species occurring on hosts belonging to the families Anacardiaceae and Annonaceae, which are described...

As part of an ongoing study of Anacardiaceae subfamily Spondioideae, the ten native and one introduced species of Spondias in the Neotropics are revised. The genus is circumscribed. Three new species, Spondiasadmirabilis, Spondiasexpeditionaria, and Spondiasglobosa, are described and illustrated; a key to the taxa found in the Neotropics and distribution maps are provided. The Paleotropical spe...

BACKGROUND Studies aimed at investigating the influence of habitat change on species phenology. Studies that investigate people's perceptions of the phenology of certain species still area few; yet this approach is important for effective decision-making for conservation. The aim of this study was to investigate the phenology of Spondias tuberosa Arruda (Anacardiaceae), a native species of econ...
