Development and Validation of a Rapid and Reliable RP-HPLC-PDA Method for the Quantification of Six Diterpenes in Copaifera duckei, Copaifera reticulata and Copaifera multijuga Oleoresins

Journal of the Brazilian Chemical Society, 2017
Oleoresins from Copaifera species are extensively used in folk medicine in Brazil, which are employed mainly in the production of cosmetic formulations in Brazil, North America and Europe. Considering the lack of validated analytical methods for the analyses of diterpenes in Copaifera oleoresins, it was developed a validated and reliable reversed-phase

Sclerophyllous structural and chemical traits of mite‐induced galls on Crinodendron patagua (Elaeocarpaceae) leaves

Plant Biology, EarlyView.
Eriophyid mites reprogram the structural and biochemical traits of sclerophyllous leaves in Crinodendron patagua, promoting the formation of nutrient‐rich and protective gall tissues. Abstract Sclerophyllous plants present a suite of traits, including small, leathery leaves with thick cuticles, dense trichomes and sclerified tissues, which are often ...

Diversity and antimicrobial activity of culturable endophytic fungi associated with the neotropical ethnomedicinal plants Copaifera langsdorffii and Copaifera pubiflora

South African Journal of Botany, 2021
Abstract Medicinal plants represent a promising reservoir of diverse endophytic fungi, including taxa that are able to produce bioactive metabolites. In Brazil, the genus Copaifera includes species that are well known in folk medicine mainly due to their ability to produce oleoresin.

Slow Recovery and Loss of Species Richness in a Semi‐Deciduous Seasonal Atlantic Forest After Selective Logging and Drought Events

Journal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Long‐term monitoring revealed slow recovery and declining species richness in a semi‐deciduous Atlantic Forest following selective logging and recurrent droughts. Despite structural increases, compositional shifts toward dominance by a few species indicate functional simplification.

Screening of Native Plant Species in the Artisanal Gold Mining Sites of Doko, Guinea: Perspectives for Phytoremediation

CLEAN – Soil, Air, Water, Volume 54, Issue 3, March 2026.
This study focuses on phytoremediation in a gold mining‐contaminated area in Doko, Guinea. Plant, soil, and rhizospheric soil samples were collected and subjected to physicochemical analyses to quantify heavy metal content. Biological indicators: bioconcentration factor (BCF), translocation factor (TF), and biological accumulation coefficient (BAC ...
