Byrsonima fagifolia Niedenzu Apolar Compounds with Antitubercular Activity

الملخص EN

Bioassay-guided fractionation of the chloroform extract of Byrsonima fagifolia leaves led to the isolation of active antitubercular compounds alkane dotriacontane (Minimal Inhibitory Concentration—MIC, 62.5 μg mL−1), triterpenoids as bassic acid (MIC = 2.5 μg mL−1), α-amyrin acetate (MIC = 62.5 μg mL−1), a mixture of lupeol, α- and β-amyrin (MIC = 31.5 μg mL−1) and a mixture of lupeol, and acetates of α- and β-amyrin (MIC = 31.5 μg mL−1).

The antimycobacterial activity was determined by the Microplate Alamar Blue Assay (MABA) and the structures of promising compounds were determined by spectroscopic analysis.

This investigation constitutes the first report of a chemical and antitubercular study of apolar compounds from B.

fagifolia Niedenzu (IK).
