| Tartalmi kivonat: | Ultrasound-assisted extraction (UAE) is one of the modern method that is applied today with the aim to decrease solvent consumption, shorten the extraction time, increase the extraction yield, and enhance the quality of extracts. In this paper, the effect of extraction time and the ratio of the sample to the solvent have been studied on the ultrasonic extraction of hawthorn fruits. The hawthorn fruit was collected from Normafa, Hungary. 10% ethanol and pure distilled water were used as extraction solvent. Folin-Ciocalteu method was performed to visualization of total phenolic compounds (TPC) and the ferric reduction antioxidant power (FRAP) method to quantify antioxidant activity in the extracts. Analyzing the results by two-way-ANOVA at significant level p < 0.05 by using SPSS software demonstrated that there is significant effect of time of extraction and the ratio of the sample to solvent. For TPC the best value was obtained at (9 min, 0.05 g/ml sample-solvent ratio) with a mean (451.106 ± 0.79 mg/L) by using 10% ethanol, and at (3 min, 0.075 g/ml sample-solvent ratio) with a mean (365.289 ± 15.96 mg/L) by using distilled water. While the best antioxidant activity was with a mean (223.033 ± 1.01 mg/L) at (9 min, 0.075 g/ml sample-solvent ratio) and (50.678 ± 2.02 mg/L) at (6 min, 0.1 g/ml sample-solvent ratio) by using the 10% ethanol and distilled water respectively. More work is needed to define better conditions for using the distilled water as a solvent in the ultrasonic extraction. |
