Chemical composition and antifungal and nematicidal activities of the hexanic and methanolic extracts of Syzygium aromaticum

In the present study, the fungicidal and nematicidal activities of the hexanic and methanolic extracts of Syzygium aromaticum were evaluated.At a concentration of 100 µg/ml, the hexanic extract inhibited 43.70% of the mycelial growth of Fusarium sp. at 48 h and 52.90% at 72 h; while at the concentration of 200 µg/ml, it inhibited 54.30% and 60% of the mycelial growth of Fusarium sp. at 48 h and at 72 h, respectively.The methanolic extract inhibited 99.87% of the hatching of Haemonchus contortus (H.contortus) eggs at a concentration of 1.25 mg/ml, with respect to the mortality of J2 larvae of it was 71.11% at the concentration of 1.25 mg/ml.Gas Chromatography coupled to mass spectrometry analysis allowed the identification of 17 compounds in total, of which eugenol, acetyl eugenol and caryophyllene were the most abundant in both hexanic and methanolic extracts.Additionally, hexatriacontane, octacosane,11, undecan-3-ol, ledene oxide-(II), and humulene were only present in the methanolic extract, while isoaromadendrene epoxide, 2-naphthalenemethanol, decahydro-α, α, 4atrimethyl-8-methyle, loxapine N -oxide, diepicedrene-1-oxide, aristolochic acid II, and trans-isoeugenol were only found in the hexanic extract.
