Abstract
In this study, anti-quorum sensing, and antioxidant activities, and chemical composition
of Acer monspessulanum subsp. monspessulanum extracts were evaluated. Determination of the antioxidant activity was revealed by
DPPH radical scavenging activity, the total phenolic content assay, and the β-carotene/linoleic acid assay. The detection of phenolic compounds was determined
using RP-HPLC. Anti-quorum sensing activity and violacein inhibition activity were
determined using Chromobacterium violaceum CV026 and C. violaceum ATCC 112 472, respectively. The determination of anti-swarming activity was carried
out with Pseudomonas aeruginosa PA01. In DPPH and total phenolic content assays, the water extract exhibited good
antioxidant activity. In the β-carotene-linoleic acid assay, ethyl acetate and ethanol extracts exhibited good lipid
peroxidation inhibition activity, demonstrating 96.95 ± 0.03 % and 95.35 ± 0.00 %
at 2.5 mg/mL concentrations, respectively. The predominant phenolic compounds of the
extracts were determined as rutin, naringin, catechin hydrate, quercetin, and protocatechuic
acid. Ethyl acetate and ethanol extracts were found to contain a high level of violacein
inhibition and anti-quorum sensing activity. The ethanol extract also showed weak
anti-swarming activity. In this first study that used Acer monspessulanum subsp. monspessulanum extracts, it was revealed that the water extract has antioxidant activity and the
ethanol and ethyl acetate extracts have anti-quorum sensing activity depending on
the phenolic compounds that it contained.
