DPPH Radical Scavenging Assay
The DPPH radical scavenging evaluation was carried
out on the basis of the reported literature.[29] Briefly,
20 μL of each compound solution [in dimethyl
sulfoxide (DMSO)] at 0.16 mM concentrations was
mixed with 180 μL of 0.1 mM DPPH methanol solution
in a 96-well microplate. Mixtures were shaken well,

and lignan glycoside from the twigs and leaves of Illicium
majus’, Fitoterapia 2018, 129, 42–46.
°
after a 0.5 h incubation period at 25 C in the dark, the
scavenging of DPPH radicals were determined accord-
ing to the measured absorbance at 517 nm by a
Multiskan FC microplate reader. The DPPH radical
scavenging activity (%) was determined by the follow-
ing equation: Radical scavenging activity (%)=[1À (As/
Ac)]×100, where Ac denotes the absorbance of the
control without samples and As denotes the absorb-
ance of the tested samples. L-Ascorbic acid acted as a
positive control. The experiment was repeated three
times.

Antimicrobial Activity Evaluation
The antibacterial activity (against Staphylococcus aur-
eus and Escherichia coli) of isolates 1–18 was also
assessed by the broth microdilution method according
to the CLSI guidelines with vancomycin and merope-
nem, respectively, as positive control drugs.[30] Neither
antibiotic exhibited antimicrobial activity at the meas-
ured concentration (<32 μg/mL).
