AB  - The genus Scorzonera is one of the most important genera in the Asteraceae family, and members of the genus have great potential in traditional medicine systems. In this article we aimed to determine skin protective and antimicrobial effects of different extracts from the roots and aerial parts of three Scorzonera species (S. hieraciifolia, S. hispanica, S. tomentosa). Antimicrobial properties were evaluated against different pathogen bacterial and fungal strains, whereas protective effects were studied in isolated mouse skin specimens exposed to hydrogen peroxide. In this biological model, the levels of l-dopa and prostaglandin E2 (PGE2) were evaluated, as markers of tyrosinase activity and inflammation, respectively. All extracts were effective in blunting the increased hydrogen peroxide-induced l-dopa turnover and PGE2 level; thus, suggesting skin protection that could be partly related to the content of flavonoids, among which rutin, in the tested extracts. Additionally, all extracts were effective as antibacterial and antifungal agents; intriguing results were observed against Trichoderma viride, which was particularly sensitive to S. tomentosa root extracts. Therefore, the present study strengthens the importance of investigating herbal preparations obtained from plants belonging to the genus Scorzonera, for the management and prevention of inflammatory and infectious skin conditions.

AB  - Several Apiaceae species, used as both food and in complementary and alternative medicine, represents a rich source of potential valuable phytopharmaceuticals which necessitates scientific contemplation. In the present study, the antioxidant, enzyme inhibitory, antimicrobial, and cytotoxic properties of methanol extracts of seven Apiaceae species, (Chaerophyllum macrospermum (Willd. ex Spreng.) Fisch. & C.A.Mey. ex Hohen, Ferula rigidula Fisch. ex DC., Ferula orientalis L., Prangos ferulacea Lindl., Prangos peucedanifolia Fenzl., Ferulago setifolia K. Koch, and Pimpinella anthriscoides Boiss.) were evaluated. Species belonging to the Prangos genus exhibited the highest total phenolic content, namely P. peucedanifolia and P. ferulacea, with values of 47.90 and 44.44 mg gallic acid equivalent/g extract, respectively. P. peucedanifolia also displayed the highest radical scavenging capacity (81.53 and 102.70 mg Trolox equivalent [TE]/g extract for 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS), respectively) and reducing power (165.87 and 100.09 mg TE/g extract for cupric reducing antioxidant capacity (CUPRAC) and ferric reducing antioxidant power (FRAP), respectively). C. macrospermum showed the most potent inhibition against Alzheimer's disease related enzymes, namely acetylcholinesterase (4.53 mg galantamine equivalent [GALAE]/g extract) and butyrylcholinesterase (3.22 mg GALAE/g extract). P. ferulacea (131.94 mg kojic acid (KAE) equivalent/g extract) and P. peucedanifolia (4.97 mmol acarbose equivalent (ACAE)/g extract) were potent inhibitors of tyrosinase and α-glucosidase, respectively. In general, studied species were able to reduce cellular viabilities. P. peucedanifolia possessed promising antibacterial potential against Bacillus cereus (Minimum inhibition concentration (MIC): 0.37 mg/mL), L. monocytogenes (MIC: 0.56 mg/mL), P. aeruginosa and Escherichia coli (MIC: 0.27 mg/mL), Salmonella typhimurium and Enterobacter cloacae (MIC: 0.75 mg/mL). F. rigidula showed the highest antifungal effect against Aspergillus ochraceus and Trichoderma viride (MIC: 0.10 mg/mL). The present findings could be the scientific starting point towards the pharmaceutical and/or commercial utilization of these Apiaceae species.

AB  - The growing awareness on implications related to the use of harsh chemicals and non-sustainable extraction
methods of bioactive compounds from plants is causing a paradigm shift towards a more eco-friendly approach.
The present study sets out to investigate the possible variation in the antioxidant, mutagenic/antimutagenic,
antimicrobial, and enzyme inhibitory properties of Origanum vulgare subsp. viridulum extracts obtained using
conventional, namely, maceration and Soxhlet extraction, and non-conventional, namely, ultrasound-assisted
(UAE), microwave-assisted (MAE), and accelerated solvent extraction (ASE), techniques. Also, chemical char-
acterization of these extracts were performed via ultrahigh-performance liquid chromatography and mass
spectrometry (UHPLC-LTQ OrbiTrap MS) technique. A total of 58 polyphenols were identified in the tested
extracts. Highest phenolic content was obtained from ASE (186.63 mg gallic acid equivalent [GAE]/g) and MAE
(170.90 mg GAE/g) extracts. Maceration extract (18.89 mg rutin equivalent [RE]/g) showed highest flavonoid
content. ASE extract showed highest activity in the DPPH (359.45 mg Trolox equivalent [TE]/g), ABTS
(679.63 mg TE/g), FRAP (1433.94 mg TE/g), and CUPRAC (1685.72 mg TE/g) assays. In terms of enzyme in-
hibition, the UAE extract showed highest activity against acetyl cholinesterase (4.55 mg galantamine equivalent
[GALAE]/g), butyryl cholinesterase (6.12 mg GALAE/g), and tyrosinase (173.87 mg kojic acid equivalent
[KAE]/g) compared with the other extracts. The extracts exhibited significant antimutagenic and antimicrobial
properties. Data collected from this study support the use of ASE and UAE in the extraction of bioactive com-
pounds from Origanum vulgare subsp. viridulum aerial parts.
