EDXRF Analysis of Amazonian Burseraceae Oleoresins
نویسندگان
چکیده
O breu exsudado das espécies de Burseraceae é amplamente utilizado tanto em cosméticos e perfumes quanto na medicina tradicional, para tratamento de diversos males. Amostras de breu de cinco espécies (Protium cf. apiculatum, P. cf. hebetatum, P. cf. heptaphyllum, P. tenuifolium e Trattinnikia peruviana), provenientes da Reserva Biológica Adolfo Ducke (Manaus-AM, Brasil), foram analisadas por FRXDE para determinação e quantificação dos elementos químicos com número atômico entre 11 e 92. Em todas as amostras foram observados os elementos S, Cl, Ca, Fe, Ti, V e Si, este último com as maiores concentrações (média de 13,1%, m/m). Além destes, foram detectados Na, P, Al, Mg, K, Cr e Mn. Excetuando-se o enxofre e o alumínio, a variação na concentração dos elementos presentes foi muito pequena (CV < 13%), sugerindo um padrão de composição inorgânica para os breus desta região. Alguns elementos foram detectados em apenas algumas espécies, sugerindo capacidades diferenciadas de absorção.

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 ...
متن کاملPhysicochemical Characterization and Biological Activities of the Triterpenic Mixture α,β-Amyrenone.
α-Amyrenone and β-amyrenone are triterpenoid isomers that occur naturally in very low concentrations in several oleoresins from Brazilian Amazon species of Protium (Burseraceae). This mixture can also be synthesized by oxidation of α,β-amyrins, obtained as major compounds from the same oleoresins. Using a very simple, high yield procedure, and using a readily commercially available mixture of α...
متن کاملEvidence for ecological divergence across a mosaic of soil types in an Amazonian tropical tree: Protium subserratum (Burseraceae).
Soil heterogeneity is an important driver of divergent natural selection in plants. Neotropical forests have the highest tree diversity on earth, and frequently, soil specialist congeners are distributed parapatrically. While the role of edaphic heterogeneity in the origin and maintenance of tropical tree diversity is unknown, it has been posited that natural selection across the patchwork of s...
متن کاملBiological activities and cytotoxicity of diterpenes from Copaifera spp. Oleoresins.
Copaifera spp. are Amazonian species widely studied and whose oleoresins are used by local people for various medicinal purposes. However, a detailed study of the activity of the main phytochemical components of these oleoresins remains to be done. Here, we studied the cytotoxicity and in vitro anti-inflammatory effects of six diterpene acids: copalic, 3-hydroxy-copalic, 3-acetoxy-copalic, hard...
متن کاملChemical Composition, Enantiomeric Distribution, and Antifungal Activity of the Oleoresin Essential Oil of Protium amazonicum from Ecuador
Background:Protium species (Burseraceae) have been used in the treatment of various diseases and conditions such as ulcers and wounds. Methods: The essential oil from the oleoresin of Protium amazonicum was obtained by hydrodistillation and analyzed by GC-MS, GC-FID, and chiral GC-MS. P. amazonicum oleoresin oil was screened for antifungal activity against Candida albicans, Aspergillus niger, a...
