Abstract
Purpose:
To develop a simple,
precise and rapid high-performance liquid
chromatographic technique coupled with photodiode
array detection (DAD) method for the simultaneous
determination of rutin, quercetin, luteolin,
genistein, galangin and curcumin in propolis.
Methods: Ultrasound-assisted
extraction was applied to isolate six antioxidant
phenolic compounds from propolis samples.
Chromatographic separation was performed using an
Eclipse XDB-C18 column (150 mm×4.6 mm, 5 μm) by
isocratic elution at 25 °C. The mobile phase
consisted of phosphate buffered saline (pH = 4.5)
and methanol (40/60, v/v). The flow rate was set at
0.8 ml/min and the effluent was monitored using a
DAD set at 260 nm.
Results: Excellent linear
correlation coefficient was observed in the range of
0.9977 to 0.9997. The reproducibility of the method
was 1.58 % (RSD) and accuracy was confirmed with
average recovery ranging from 95.71 to 104.26 %. Six
antioxidant phenolic compounds in propolis samples
were successfully determined within 50 min.
Conclusion: The proposed isocratic LC
method gave good separation and accurate
determination of rutin, quercetin, luteolin,
genistein, galangin and curcumin in propolis. The
proposed method showed good sensitivity, linearity,
repeatability and accuracy.
