HPLC analyses were performed using a Waters HPLC system
(Guyancourt, Versailles, France) consisting of aWaters 600E pump,
a Waters 717+ auto sampler, a Waters 2996 photodiode-array
detector. The HPLC pumps, automatic sample, column temperature
and diode-array system were monitored and controlled by the
Waters Empower 2 Chromatography Data software program. The
chromatographic separation was carried out on a Purospher Star
RP-18 end-capped column (250 4 mm I.D.; 5-lm particle size
from Merck), with a RP18 guard column (4 4 mm I.D.; 5-lm particle
size also from Merck). The injection volume was 20 lL. All
analyses were repeated at least three times, only mean values were
reported.
