ABSTRACT
Objectives:
The aim of this study was the development and validation of a fast method to quantify artepillin C in green propolis using ultra high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UHPLC-ESI-MS/MS).Methods:
High purity (97.8%) artepillin C was isolated from green propolis using chromatography techniques. Quantification was performed using a C18 (2.1 x 100 mm; 1.7 µm) column, gradient of water and methanol (with 0.01% formic acid) as mobile phase, at a flow rate of 0.4 mL/min and 45 ºC in temperature. A mass spectrometer operated in selected reaction monitoring mode to monitor the deprotonated molecular ion of artepillin C (m/z 299) > fragment ion (m/z 200.12). Several parameters such as specificity, linearity, limit of detection (LOD), limit of quantitation (LOQ), precision, accuracy, and robustness were determined.Results:
The method was linear in the 50 400 µg/mL range (r2 = 0.9906), showing LOD = 10.79 µg/mL and LOQ = 32.70 µg/mL with satisfactory intra-day and inter-day precision with relative standard deviation (RSD %) of 1.9% and 3.4%, respectively. The accuracy showed recovery of 93-104%, the method was robust and artepillin C was quantified in green propolis at 6.51%.Conclusions:
The proposed method showed advantages in comparison with other methods, such as short analysis time and high selectivity for artepillin C.
