AB  - In the present study, rosehip (Rosa canina L.) extract was successfully encapsulated in phospholipid liposomes using a single-step procedure named the proliposome method. Part of the obtained liposomes was subjected to UV irradiation and non-treated (native) and UV-irradiated liposomes were further characterized in terms of encapsulation efficiency, chemical composition (HPLC analysis), antioxidant capacity, particle size, PDI, zeta potential, conductivity, mobility, and antioxidant capacity. Raman spectroscopy as well as DSC analysis were applied to evaluate the influence of UV irradiation on the physicochemical properties of liposomes. The encapsulation efficiency of extract-loaded liposomes was higher than 90%; the average size was 251.5 nm; the zeta potential was −22.4 mV; and the conductivity was found to be 0.007 mS/cm. UV irradiation did not cause a change in the mentioned parameters. In addition, irradiation did not affect the antioxidant potential of the liposome–extract system. Raman spectroscopy indicated that the extract was completely covered by the lipid membrane during liposome entrapment, and the peroxidation process was minimized by the presence of rosehip extract in liposomes. These results may guide the potential application of rosehip extract-loaded liposomes in the food, pharmaceutical, or cosmetic industries, particularly when liposomal sterilization is needed.

AB  - Aromatic plant species of family Lamiaceae are important medicinal plants because of their antioxidant, antimicrobial, antispasmodic, expectorant, stimulant and diuretic properties. In this study T. serpyllum herba was evaluated as a source of polyphenolic compounds, which are extracted by the application of ultrasound probe instead of the traditional solvent extraction. Ultrasound extraction has become a good alternative extraction method when compared to classical methods due to its high efficiency, low energy and solvent consumption. Ultrasound assisted extraction is a well established method in the processing of plant material, particularly to extract bioactive substances such as polyphenols. Optimization of the extraction was carried out through varying degrees of fragmentation (0.3, 0.7 and 1.5), time of extraction (3, 7 and 10 minutes) and ratio drugs:solvent (1:10, 1:20 and 1:30) in 30% ethanol as an extraction medium. Extraction efficiency was expressed via total polyphenols content (Folin-Ciocalteu method) and antioxidant activity (DPPH method). The highest total polyphenols content and antioxidant activity were recorded in extract with a degree of fragmentation of 0.3 and ratio drug:solvent 1:30 after 3 minutes, 23.03 mg/L GA and IC50 3.00 mg/ml, respectively. The lowest total polyphenols content and antioxidant capacity were obtained in extract with a degree of fragmentation of 1.5 and ratio drug:solvent 1:10 (12.06 mg/L GA and IC50 4.78 mg/ml, respectively). This study found that both total polyphenols and antioxidant activities determined were significantly affected by the degree of fragmentation and ratio drugs:solvent. Also, the levels of total soluble phenolic compounds were positively correlated with free radical scavenging activities against DPPH radicals.

AB  - Wild Thyme (Thymus serpyllum) is perennial, herbaceous plant of Lamiaceae family. It has
aromatic, antioxidant, antiseptic, anthelmintic, repelent, antirheumatic, expectorant,
antispasmotic, carminative, sedative and diuretic properties. Optimization of the extraction by
maceration of T. serpyllum was carried out through varying degrees of fragmentation (0.3, 0.7
and 1.5) and the type of solvent (water, ethanol and mixtures of those in weight ratio 50:50 and
70:30). Extraction efficiency was expressed via total polyphenols content and antioxidant
activity. The highest total polyphenols content and antioxidant activity were recorded in 50%
ethanolic extract, with a degree of fragmentation of 0.3, 921,51 mg GA/g DW and 0,538 mM
Trolox/g DW, respectively. No significant differences were observed between total polyphenols
and antioxidant activity in water and in 70% ethanolic extracts. The lowest total polyphenols
content and antioxidant activity were obtained in 96% ethanolic extract (70.73 mg GA/g DW and
0,142 mM Trolox/g DW, respectively).
