Cherry laurel (prunus laurocerasus) extract and liposome encapsulation

Aim. The study aimed to determine the antioxidant activity and the number of phenolic substances of cherry laurel fruit and to reveal the usability of the fruit for other studies. Methods. Cherry laurel fruit was separated from the seeds and pureed. The fruit was extracted by ultrasonic extraction. Ethanol was used as a solvent. The fruit was extracted by acidic and ethanol extraction. The solvent was removed in a rotary evaporator at 50–60 C. For liposome production, lecithin solution was first prepared. Chitosan solution was added to the resulting reduced-size liposome and mixed overnight. Liposomes with and without extracts were prepared. Results. The DPPH value of the acidic fruit extract was determined as 66.4 mg TEAA/kg DM, the CUPRAC analysis result was 42.4 mg/kg DM, and the total phenolic content was 3.9 mg GAE/kg DM. Conclusion. The data obtained from this study show that cherry laurel fruit has good antioxidant activity and phenolic substance content and that the fruit can be a raw material for anticancer studies in this field.
