  The genus Verbascum, commonly known as "mullein", bears several species traditionally used to treat various infections, inflammations and wounds. In this study, extracts from V. bombyciferum, an endemic Verbascum species from Turkey, obtained by different solvents and extraction techniques, were investigated for their bioactive contents using spectrophotometry and high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and evaluated for their antioxidant, as well as enzyme inhibitory potentials. While spectrophotometric determination revealed the homogenizer assisted extraction/methanolic extract to yield the highest total phenolic and flavonoid contents (41.80 ± 0.70 mg GAE/g and 39.44 ± 0.30 mg RE/g, respectively), the most significant total bioactive compounds (polyphenols) in the amount of 272.862 mg kg−1, established by HPLC-MS/MS analysis, was noted for the maceration/methanolic extract. Overall, the extracts showed varied antioxidant potency, displaying free radical scavenging ability (DPPH assay: 1.04–51.33 mg TE/g; ABTS assay: 80.04–85.60 mg TE/g), reducing power (CUPRAC: 51.48–183.26 mg TE/g; FRAP: 36.33–90.04 mg TE/g; metal chelating activity (18.48–19.80 mg EDTAE/g) and total antioxidant capacity (phosphomolybdenum assay: 0.78–1.92 mmol TE/g). However, extract of homogenizer assisted extraction/methanol exhibited the highest antioxidant activity in most assays. Only the maceration/methanolic extract inhibited all the studied enzymes (acetylcholinetserase: 2.02 ± 0.20 mg GALAE/g; butyrylcholinesterase: 4.57 ± 0.09 mg GALAE/g; tyrosinase 21.44 ± 3.41 mg KAE/g and amylase: 0.46 ± 0.01 mmol ACAE/g). This study is the first attempt to highlight the potential industrial applications of the endemic plant V. bombyciferum, as a natural source of bioactive compounds that could be considered for future development of phytopharmaceuticals, targeting specific oxidative stress-linked diseases including diabetes, skin hyperpigmentation, and neurological disorders.

  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.

  Several species of the Apiaceae family have been employed in traditional cultures for their curative virtues. The present study focused on five Apiaceae species, (Falcaria vulgaris (FV), Smyrniopsis aucheri (SA), Smyrniopsis munzurdagensis (SM), Smyrnium cordifolium (SC), and Actinolema macrolema (AM)). The antioxidant, enzyme inhibitory (α-amylase, α-glucosidase, acetyl- and butyrylcholinesterase, lipase, and tyrosinase), antimicrobial, phytochemical, and cytotoxicity profiles of the methanol extracts of the selected Apiaceae species were determined. SC extract (35.68 mg gallic acid equivalent/g extract) possessed the highest phenolic content while the AM extract (56.79 mg rutin equivalent/g extract) had the highest flavonoid content. HPLC-ESI-MS (High performance liquid chromatography-electrospray tandem mass spectrometry) analyses showed presence of ferulic acid in all the five species. SC extract exhibited high radical scavenging (59.28 and 94.31 mg Trolox equivalent [TE]/g extract, DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid), respectively) and reducing activity (161.44 and 113.62 mg TE/g extract, for CUPRAC (cupric reducing antioxidant capacity) and FRAP (ferric reducing antioxidant power), respectively). SM extract exhibited the highest cholinesterase's inhibitory action (3.82 and 4.76 mg galantamine equivalent/g extract, for acetyl- and butyrylcholinesterase, respectively). The extracts showed higher inhibition against α-glucosidase (7.32-11.99 mmol acarbose equivalent [ACAE]/g extract) compared to α-amylase (0.51-0.55 mmol ACAE/g extract). SC extract was the most active (137.54 mg kojic acid equivalent/g extract) tyrosinase inhibitor and FV extract (113.75 mg Orlistat equivalent/g) the best lipase inhibitor. SM extract showed potent antibacterial effect against B. cereus (MIC (minimum inhibitory concentration) 0.180 mg/mL), P. mirabilis (MIC 0.180 mg/mL), M. flavus (MIC 0.560 mg/mL), P. aeruginosa (MIC 0.275 mg/mL), and S. typhimurium (MIC 1.500 mg/mL). FV extract (MIC 0.140 mg/mL) suppressed A. fumigatus growth. Cytotoxicity was assessed on murine macrophage (RAW 264.7), human embryonic kidney (HEK 293), and human hepatocellular carcinoma (HepG2) cell lines. FV (60.3%) and SM (57.4%) showed the highest reduction on RAW 264.7 cellular viability, whereas SM (74.1%) showed toxicity against HepG2. This study supports that the Apiaceae species could be considered as promising candidates for the development of novel pharmacophores for the management of several human ailments.

  Kundmannia anatolica HUB.-MOR. and Kundmannia syriaca BOISS. are two endemic species of Apiaceae diversified in Turkey. In the present study, the essential oil composition and antimicrobial activity of these endemic species collected from Southeast Anatolia region of Turkey were investigated. Essential oils of aerial parts were obtained by hydro distillation method and analyzed by GC-MS/FID. Acetone, chloroform and methanol extracts of aerial parts of the plants were tested against seven bacteria and three yeasts by disc diffusion method for antimicrobial assays and minimum inhibition concentrations (MIC) were determined. Spathulenol, curdione, apritone, germacrene-d and- (-) globulol were the major components of K. anatolica. In the essential oil of K. syriaca, spathulenol, germacrene-d, bioallethrin, 12-norcyercene-B and beta methadol were determined as the main compounds. The most abundant compound of K anatolica and K. syriaca was spathulenol with 17.40%-19.53% ratio in the GC-MS and 19.7%, 24.99% ratio in GC-FID results, respectively. Aerial parts extracts of K. anatolica and K. syriaca exhibited remarkable antimicrobial activity to all tested microorganisms except for Candida albicans. (C) 2015 Elsevier B.V. All rights reserved.
