Most of plant extracts constituents have been found to show interesting biological activities: against specific pathogens, antioxidant, hypocholesterolemic [62], and antibacterial [63]. Several activities have been reported for \(n\)-hexadecanoic acid, suggesting the rationale for the traditional use of _Albizia adianthifolia_ and _Pterocarpus angolensis_ extracts. Moreover, \(n\)-hexadecanoic acid isolated from heartwood and stem bark of \(A\). _adianthifolia_ (\(n\)-hexane extract) was reported as anti-inflammatory [64], an antioxidant, hypocholesterolemic, a nematicide, a pesticide, anti-androgenic, hemolytic, a 5-alpha reductase inhibitor [62], and a potent mosquito larvicide [63]. Oleic acid could have antibacterial activity [65]. A chloroform extract of \(A\). _adianthifolia_ contains 9,12-octadecaenoic acid (Z,Z)-, methyl ester and exhibited an anti-cancer activity [66]. [PERSON] et al. [67] indicated that volatile compounds, such as tetradecanal, dodecanol, and 2,4-dimethyl-6-tert-butylphenol, individually exhibited a strong antifungal effect against the fungal isolates of _Verticillium dahliae_and _Fusarium oxysporum_, although those compounds were found in low amounts in BEE and BME by GC-MS. Tetradecanoic acid showed larvicidal and repellent activities [68]. 2-Propanone, also called acetone or dimethyl ketone, seemed to be an effective compound in our study. Similarly, many authors previously found, by GC-MS, that the active compounds included alcohols, esters, ketones, and acids and they inhibited phytopathogenic fungi [69]. The fatty acid methyl ester could play a role in the decomposition of mycotoxins, based on the antibacterial and antifungal activity. Hexadecanoic acid, methyl ester and octadecanoic acid proved to be antimicrobial molecules [63; 70]. Finally, there is a need for further studies on the most abundant components found by the GC-MS analysis to evaluate their antimycotoxic activities individually.
