Matrix solid-phase dispersion (MSPD) methodology as a quick and easy extraction method has been developed to extract oleuropein from Olea europaea leaves. This method has been compared with conventional maceration and Soxhlet extraction (SOXE) methods. Variables affecting MSPD;
such as the sorbent material;
the ratio of sample to sorbent material;
elution solvent;
and volume of the elution solvent;
have been fully evaluated and optimized. Oleuropein was successfully extracted by silica sorbent with 350 μL of dichloromethane- methanol (70 + 30;
v/v) as the elution solvent. The calibration curve showed good linearity (r2 = 0.9985) and precision (RSD;
