Syzygium aromaticum (Clove)

This work aimed to evaluate the fungicidal activity of oil-in-water (A/A) nanoemulsions of hydroalcoholic extract and essential oil from Syzygium aromaticum shoots. The action of the biotech product was tested against three strains of fungi Aspergillus niger, Colletotrichum gloeosporioides, Penicillium chrysogenum. For the antifungal action of the essential oil nanoemulsion, the MIC obtained was 25 g mL-1, 25 g mL1and 50 g mL-1 against A. niger, C. gloeosporioides and P. chrysogenum, respectively, for the hydroalcoholic extract nanoemulsion the result was 50 g mL-1, 50 g mL-1and 100 g mL-1for A. niger, C. gloeosporioides and P. chrysogenum, respectively. On the other hand, the MIC of the nanoemulsion of the essential oil showed activity against A. niger of 25 g mL-1 and against C. gloeosporioides showed inhibition at 25 g mL-1 and the nanoemulsion of the hydroalcoholic extract had its best performance against A. niger of 50 g mL-1 and against C. gloeosporioides, which showed inhibition at 50 g mL-1. Finally, this study points to the nanoemulsion of S. aromaticum as an alternative fungicide in the control and combat of pathogenic fungi.
