Researchers Isolate Antimycobacterial Compound From Plant
A study identifies six compounds in Zanthoxylum flavum subsp. pistaciifolium leaves with potential medical properties.
Updated on Oct. 22, 2026 in Botany
Scientists have isolated six distinct compounds from the leaves of the Zanthoxylum flavum subsp. pistaciifolium plant, a species native to Cuba. One specific compound, gamma-fagarine, demonstrated significant antimycobacterial activity and selective cytotoxicity against cancer cell lines.
Why it matters
The findings provide a scientific basis for the traditional use of the plant in treating respiratory infections. Identifying bioactive compounds offers potential avenues for developing new therapeutic agents for tuberculosis and related conditions.
Researchers utilized LC-MS, 1D/2D NMR, and ECD spectra to characterize the compounds. The study tested gamma-fagarine at 10 µM, demonstrating selective cytotoxicity against A549, A2780, and MCF-7 cell lines while showing no toxicity toward MRC-5 fibroblasts.
The players
Zanthoxylum flavum subsp. pistaciifolium
This plant species, native to Cuba, is traditionally utilized in folk medicine for the treatment of various respiratory infections.
The details
The research team employed a checkerboard assay to test the synergy between gamma-fagarine and rifampicin. Molecular docking predictions were also developed, offering a structural hypothesis for how these compounds interact with target biological pathways.
