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
