Abstract

Hydroalcoholic extract from Jabuticaba peels was evaluated for the chemical profile, antioxidant potential, cytotoxicity, and anti-Sporothrix brasiliensis activities against both dimorphic phases. Higher phenolic content (14.91 ± 0.97) compared to flavonoid (2.05 ± 1.00) associated with the ellagic acid (1.93 ± 0.03; LC-MS), and a good scavenging ability against ABST and DPPH radicals was noted. On MDBK cells, elevated cell viability (>90%) was demonstrated between 0.39 and 0.097 mg/ml (MTT assay). Mycelial (CLSI M38-A2) and yeast (CLSI M27-A3) phases of 18 isolates of Sporothrix brasiliensis from cats (n = 8), dogs (n = 8) and humans (n = 2) were used. They were identified itraconazole-susceptible and itraconazole-resistant isolates in both phases, which were all inhibited (MIC of ≤1.56–6.25 mg/ml for both phases) and killed (MFC of ≤1.56–12.5 mg/ml for mycelial; ≤1.56–50 mg/ml for yeast) by Jabuticaba. For the first time, these findings highlighted the potential usefulness of hydroalcoholic extract from Jabuticaba peel as a promising antifungal against sporotrichosis.
