Eperua oleifera Ducke (Fabaceae) Oilresin Chemical Composition and the Isolation of a Natural Diterpenic Acid Methyl Ester

Chemistry &Biodiversity, EarlyView.
Eperua oleifera (Fabaceae) oilresin presents not only diterpenic acids, but also diterpenic acid methyl ester. ABSTRACT Eperua oleifera Ducke, commonly known as “copaíba‐jacaré,” produces oilresins traditionally used in folk medicine for wound healing and as antifungal and antibacterial agents, similar to those of Copaifera species.

Synthesis and Characterization of Dummy Template‐Based Molecularly Imprinted Polymers for Extraction of Aflatoxins in Food Samples

Chemistry &Biodiversity, EarlyView.
Five dummy templates and two functional monomers were systematically evaluated for the preparation of selective MIPs for aflatoxins. 5,7‐Dimethoxycoumarin and methacrylic acid were found to produce highly selective MIPs, and the adsorbent was characterized by FTIR, TGA, and SEM.

Manganese‐Induced Production of Antioxidant Polyene Steroids in the Extremophile Fungus Talaromyces fuscoviridis Isolated From Copper‐Mine Soil

Chemistry &Biodiversity, EarlyView.
ABSTRACT The fungus Talaromyces fuscoviridis was isolated from soil collected in a copper‐mine tailings basin in Pará State, Brazil, an extreme environment that can induce the production of bioactive secondary metabolites. Extracts and fractions obtained after cultivation were analyzed by liquid chromatography coupled to high‐resolution mass ...

Bioprospecting of Labdane‐Type Diterpenes From Austroeupatorium laetevirens: Molecular Networking, Structural Elucidation, and Biological Activity Evaluation

Chemistry &Biodiversity, EarlyView.
ABSTRACT Labdane‐type diterpenes are the main specialized metabolites in the Austroeupatorium genus, known for diverse biological activities. This study employed molecular networking to facilitate the identification of labdanes in Austroeupatorium laetevirens, alongside isolation, structural elucidation, and evaluation of anti‐Mycobacterium ...
