Objective

To establish a mothod for determination of oleuropein content in Oleaeuropaea L. related products by high performance liquid chromatography.

Methods

Ultrasonic-assisted extraction was employed to extract oleuropein from samples. The extraction conditions and mobile phase composition were optimized through single-factor experiments. The developed method was subjected to systematic method validation and subsequently applied to the determination of oleuropein content in commercially available products.

Results

The optimal extraction conditions were 30% methanol with a solid-to-liquid ratio of 1:40 (g:mL), extraction temperature of 45 ℃ and extraction for 2 times. The chromatographic conditions consisted of acetonitrile-water (25:75, V:V) with a detection wavelength of 232 nm. Methodological validation demonstrated a good linear relationship (r2=0.999), and the precision [relative standard deviations (RSDs)<4%], repeatability (RSDs<3%) and spiked recovery (87.49%–115.00%) all met the required criteria.The oleuropein content in commercially available products typically ranges from 0 to 10 mg/g.

Conclusion

The method developed is highly sensitive and specific, can overcome complex matrix interferences, and is suitable for determining the content of oleuropein in Oleaeuropaea L. related products.
