AB  - Salvia nemorosa L. is a rich source of bioactive constituents. We have used different solvents to obtain 14 different extracts in order to evaluate solvents impact on S. nemorosa inflorescences bioactivities. Firstly, the extraction yield, chemical composition and cytotoxic properties towards HaCaT cell line were elaborated. Afterwards, we have studied the extracts bioactivity in terms of wound healing, antioxidant and antidiabetic potentials as well as antimicrobial and antibiofilm capacities; followed by the determination of the antimicrobial mechanism. The extracts yield ranged from 3.03% to 15.75% and they were dominated by epigallocatechin gallate and rosmarinic acid. The majority of extracts did not possess cytotoxic properties towards human keratinocytes. Butanol was the most appropriate solvent for the improvement of wound healing capacity. Combined extraction with ethanol and water resulted in the highest antioxidant potential of the extracts that could be attributed to the high abundance of detected polyphenols. Extraction with butanol led to the increased inhibition towards enzymes linked to type 2-diabetes and increase in antimicrobial capacities. The extracts have shown antibiofilm potential towards Staphylococcus lugdunensis biofilms with more than 90% inhibition for the most active ones. The selected extract EB7 reduced bacterial ability to adhere to human keratinocytes and provided immunomodulatory action in HaCaT cells exposed to S. lugdunensis. The antibacterial mechanism of action of the same extract was associated with moderate perturbation in the cell membrane integrity and with the reduction in bacterial mitochondrial activity. S. nemorosa inflorescences were abundant sources of bioactive polyphenols and with different extraction solvents their bioactivities were further improved. This study reported for the first time the effects of extraction solvents on various bioactivities of S. nemorosa inflorescences, supporting S. nemorosa role as a natural bioactive therapeutic agent with possible antioxidant, antidiabetic and antimicrobial applications.

AB  - Despite the significant advances in drug development we are witnessing the inability of health systems to combat both neurodegenerative diseases and cancers, especially glioblastoma. Hence, natural products are comprehen-sively studied in order to provide novel therapeutic options. This study aimed to explore anti-neurodegenerative and anti-glioblastoma potential of extract of Phlomis fruticosa L. using in vitro model systems. It was found that the methanol extract of P. fruticosa was able to efficiently reduce activities of enzymes linked to neurodegenera-tive disease including acetylcholinesterase, butyrylcholinesterase and tyrosinase. Furthermore, P. fruticosa ex-tract has shown excellent antioxidant potential, as evidenced by six different methods. Analysis of cytotoxic ef-fect of P. fruticosa extract on A172 glioblastoma cell line revealed that the concentration of the extract necessary for 50 % inhibition of A172 growth (IC50) was 710 mu g/mL. The extract did not induce changes in proliferation and morphology of A172 glioblastoma cells. On the other side, production of ROS was increased in A172 cells treated with the extract. Observed cytotoxic effect of P. fruticosa extract might be based on increase in ROS generation upon treatment. Quantitative chemical analysis revealed the presence of twelve different polyphenols with the cis 3-O-caffeoylquinic acid being the most abundant. This study provided scientific evidence for further exploration of P. fruticosa as a promising natural anti-neurodegenerative therapeutic option.

AB  - The aim of this study was to evaluate the effect of enriching a complex food matrix (FM) with grape extracts on polyphenol content, composition, bioaccessibility and antioxidant activity during digestion. The grape extracts and FM were separately tested under the same conditions as controls. The FM by itself contains a significant amount of phenolic acids and flavonols, influencing the final recovery of polyphenols from grape extracts. The FM significantly increased the total recovery of polyphenols after digestion of grape seed extracts compared to those digested without the FM; however, a low recovery of proantocyanidins and total flavonoids was observed. Digestive fluids and FM compounds significantly increased the total polyphenol content of grape digests and significantly contributed to their ABTS(center dot+) scavenging activity and ferrous-ion-chelating capacity. The present study suggested that enrichment of meat-and cereal-based products with grape polyphenol extracts could be a good strategy to formulate a healthier diet.
