The genus Salvia has recently attracted great attention due to its notable biological activities. Within this context, in this study, the chemical characterization and biological effects of three extracts (dichloromethane (DCM), methanol (MeOH), and water) from three Salvia species (S. blepharochlaena (SB), S. euphratica var. leiocalycina (SE), and S. verticillata subsp. amasica (SV)) were assessed. For the chemical characterization, the qualitative and quantitative analysis of phenolic components in the methanol extracts was carried out by high-performance liquid chromatography with electrospray ionization mass spectrometry detection (HPLC-UV-ESI-MSn). Total phenolic, flavonoid and phenolic acid contents were also studied. Concerning the biological effects, antioxidant (DPPH and ABTS free radical scavenging; ferric (FRAP) and cupric (CUPRAC) reducing power; phosphomolybdenum, and metal chelating assays), enzyme inhibitory (cholinesterase, tyrosinase, amylase, glucosidase, lipase, and elastase) and cytotoxic effects (A-549 and MCF-7 cell lines) were evaluated. After the evaluation of the phytochemical profile by HPLC-UV-ESI-MSn, it was observed that the main compound in the analyzed extracts was rosmarinic acid, which was present at high concentrations, particularly in SV, which presented rosmarinic acid levels higher than the usual levels found in other Salvia species or related plants. Generally, the SV-water extract presented the strongest antioxidant abilities with higher levels of total bioactive compounds. However, the studied DCM extracts had higher enzyme inhibitory potentials compared with MeOH and water extracts. SE-DCM exerted the most potent cytotoxic effects, followed by SB-water and SB-MeOH extracts.

Throughout human civilization, elderberry (Sambucus nigra L.) has been used as a traditional drug and addition to various dishes. Although it is a widespread plant species, it is still being researched and rarely used to obtain new products. In this study, we focused on the chemical and phytochemical composition and biological and pharmacological effects of elderberry wine, obtained by applying different temperature treatments (without temperature treatment – W1; 60 °C, 5 min – W2; 60 °C, 10 min – W3; and 70 °C, 5 min – W4). HPLC-MS/MS and spectrophotometric techniques determined the chemical and phytochemical profiles of obtained wines. The main compounds in analyzed wines were p-Hydroxybenzoic, protocatechuic and chlorogenic acids, quercetin, quercetin-3-O-hexoside, and rutin. To assess the biological potential, antioxidant, neuroprotective (acetyl- and butyrylcholinesterase inhibition), antityrosinase, and antidiabetic (amylase inhibition and glucosidase inhibition) abilities were examined. Wine W4 showed the strongest antioxidant activity, which correlated well with the high phenol content. The best inhibitory effect of β-glucosidase was observed in wine W3. However, the most potent tyrosinase inhibitor was wine W4. The presented results prove elderberry wine's high biological and industrial potential and open new avenues for formulating new products that could be brought to market.
