Plants that produce secondary metabolites with allelopathic activity or phytotoxicity can be biotechnologically important, serving as sources of allelochemicals, and thus contributing to the agroindustrial sector. Vismia japurensis (Hypericaceae) is an Amazonian species that grows in clumps called vismia...
RESUMO Objetivo identificar as atividades farmacológicas da manteiga de bacuri (Platonia insignis Mart.). Métodos revisão integrativa, realizada nas bases de dados Literatura Latino-americana e do Caribe em Ciências da Saúde, Cumulative Index to Nursing and Allied Health Literature, EMBASE, MEDL...
Introduction: The Vismia genus belongs to the Hypericaceae family and comprises around 57 species of which 17 have been located in Venezuela. Previous investigations have been carried out in extracts as well as pure isolated compounds, revealing antimicrobial, antioxidant and anti-HIV, among other, biolo...
Although the number of recently described Tovomita species is relatively high, much more remains to be done, given that each new survey of representative Amazonian collections reveals many potentially undescribed taxa. In the treatment for Tovomita published in Flora of the Venezuelan Guayana, at least s...
The objective of this work was to evaluate the antioxidant and inhibitory activities of the ethanolic extracts of the mangosteen (Garcinia mangostana L.) grown in Montenegro, Quindío, Colombia, in three stages of maturation, including the edible (pulp) and inedible parts (pericarp and peduncle). The alc...

Background: This research is intended to determine suitable types and concentrations of plant growth regulators (PGRs) to induce callus on stem and leaf sections of 4 species of the genus Garcinia, namely, Garcinia mangostana, Garcinia schomburgkiana, Garcinia cowa, and Garcinia celebica. The base medium...
Abstract In this study was evaluated the influence of glutamine supplementation on the endogenous content of amino acids, proteins, total phenolics, flavonoids and proanthocyanidins in Bacupari callus. The explants were inoculated in MS medium, MS with half concentration of the nitrogen salts (MS½) and ...

Abstract:Vismia genus is distributed mainly in tropical and subtropical regions of Central, South America and some areas of Africa. According to previous investigations, antioxidant potential of Vismia species might be related to anthrones, anthraquinones, flavonoids and phenol derivatives biosynthesized...
