(2019) Multifaceted activity of millipede secretions: Members of the millipede order Julida rely on dominantly quinonic defensive secretions with Antioxidant, antineurodegenerative, and anti- several minor, non-quinonic components. The free radical-scavenging activities of ethanol, Fusarium effects of the defensive secretions of methanol, hexane, and dichloromethane extracts of defensive secretions emitted by Pachyiulus hungaricus (Karsch, 1881) and Megaphyllum unilineatum (C. L. Koch, 1838) Pachyiulus hungaricus (Karsch, 1881) and Megaphyllum unilineatum (C. L. Koch, 1838) (Diplopoda: Julida). PLoS ONE 14(1): e0209999. were investigated using the ABTS, DPPH, and total reducing power (TRP) tests. The https://doi.org/10.1371/journal.pone.0209999 obtained extracts were also tested for inhibition of acetylcholinesterase and tyrosinase Editor: David A. Lightfoot, College of Agricultural activity. Finally, the antifungal potential of both julid extracts was evaluated against seven Sciences, UNITED STATES Fusarium species. Secretions of both species showed activity against free radicals, acetyl- Received: August 28, 2018 cholinesterase, tyrosinase, and all of the selected fungal species.
