Cannabinoids From Trema micranthum (L.) Blume (Cannabaceae): A Cannabinoid Profiling System

Chemistry &Biodiversity, EarlyView.
ABSTRACT Trema micranthum (L.) Blume is a species from the Cannabaceae botanical family, present all over the tropics. A recent study conducted by our group identified the presence of cannabidiol (CBD), Δ9‐tetrahydrocannabinol, cannabidiolic acid, and tetrahydrocannabinolic acid‐A in T. micranthum extracts.

Eugenia brasiliensis: Analysis of the Chemical Profile and Evaluation of Cytotoxic Potential

Chemistry &Biodiversity, EarlyView.
Leaves of Eugenia brasiliensis were dried, crushed and macerated with polarity increment. The antiporliferative and anti‐migratory potential and the cell cycle were evaluated. 28 compounds were tentatively identified by mass sceptrometry. ABSTRACT This work evaluated the antiproliferative potential of Eugenia brasiliensis leaf extracts against the HeLa

Flavonoid Profile, Biological Potentials, and In Silico Approaches of Methanol Extracts on AChE: Amaranthus retroflexus L.

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study investigated the flavonoid compounds and their biological activities in methanol extracts obtained from root, stem, leaf, and flower parts of Amaranthus retroflexus L. Flavonoids in the extracts were characterized for the first time by liquid chromatography–highresolution mass spectrometry (LC–HRMS), and a total of eight flavonoid ...
