The objective is to quantify the carbon content (C) of reservoirs plant biomass different species in a fragment Atlantic Forest Northeast Brazil. Ten high absolute density were selected. We sampled from leaf and wood compartments each determine C content. There was difference levels between species. leaves varied 451.4 456.7 g kg-1. 451.7 456.8 group formed by families Burseraceae, Moraceae, Sa...

The Burseraceae are represented in Peru by six genera and 50 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), all of them trees. Here we recognize two endemic taxa in two genera. These taxa are found in the Very Humid Lowland Amazonian Forests and Very Humid Premontane Forest regions, between 150 and 1300 m elevation. Neither species has been registered within Peru’s protected areas ...

Protium subserratum (Burseraceae) is a neotropical tree species that is comprised of several habitat-specific ecotypes having distinct defense chemical profiles. A previously unknown triterpene, 25,30-dicarboxy-26,27,28,29-tetraacetoxy-10,11,14,15-tetrahydrosqualene, was isolated from P. subserratum young leaf tissue of one ecotype growing in Peru. The structure of 1 was determined by spectrosc...

Pentacyclic triterpenes are ubiquitously distributed throughout the plant kingdom, in a free form as aglycones or in combined forms, and have long been known to have a number of biological effects. The compounds-amyrin and -amyrin are commonly found in medicinal plants and oleo-resin obtained by bark incision of several species of Bursera or Protium of the Burseraceae family. Both in vitro a...

Precise identification of plant species requires a high level of knowledge by taxonomists and presence of reproductive material. This represents a major limitation for those working with seedlings and juveniles, which differ morphologically from adults and do not bear reproductive structures. Near-infrared spectroscopy (FT-NIR) has previously been shown to be effective in species discrimination...

The barks and leaves extracts of Canarium patentinervium Miq. (Burseraceae Kunth.) were investigated for cyclooxygenase (COX) and 5-lipoxygenase (LOX) inhibition via in vitro models. The corresponding antioxidative power of the plant extract was also tested via nonenzyme and enzyme in vitro assays. The ethanolic extract of leaves inhibited the enzymatic activity of 5-LOX, COX-1, and COX-2 with ...
