    A GC-MS method validation for quantitative investigation of some chemical markers inSalvia hypargeiaFisch. & CA Mey. of Turkey: Enzyme inhibitory potential of ferruginol
    (Wiley, 2020) Bakir, Derya; Akdeniz, Mehmet; Ertas, Abdulselam; Yilmaz, Mustafa A.; Yener, Ismail; Firat, Mehmet; Kolak, Ufuk
    In the present study, a GC-MS method used for quantitative screening of 26 compounds (sclareolide, sclareol, ferruginol, cryptanol, 6,7-dehydroroyleanone, suginal, 9,10-dihydro-7,8-dimethyl-2-(1-methylethyl) phenanthren-3-ol, sugiol, inuroyleanone, 12-demethylmulticauline, 7 alpha-hydroxy-beta-sitosterol, stigmasterol, sitosterol, salvigenin, sinensetin,alpha-amyrin, lupeol, lupenone, 3-acetyl lupeol, 1 alpha,21 alpha-dihydroxy-2,3-(1 ' 1 '-dimethyl-dioxymethylene) urs-9(11),12-dien, uvaol, betulin, pyxinol, lup-(20),29-ene-2 alpha-hydroxy-3 beta-acetate, betulin 3 beta, 28 beta-diacetate, 21 alpha-hydroxy,2 alpha,3 beta-diacetoxy urs-9(11),12-dien) specific to TurkishSalviaspecies was developed and validated. According to the GC-MS analysis results,Salvia hypargeiaFisch. & C.A. Mey. roots were found to be rich in ferruginol (30787.97 mu g/g extract) and lupenone (23276.21 mu g/g extract), and leaves in lupeol (20625.92 mu g/g extract). Additionally, the essential oil and aroma contents of this species were identified by GC-MS technique. According to the LC-MS/MS results, especiallyS. hypargeialeaf extract was rich in rosmarinic acid (38035.7 mu g/g extract) and isoquercitrin (4136.91 mu g/g extract). Furthermore, anticholinesterase, antiurease, antityrosinase and antielastase inhibitory, antioxidant, cytotoxic activities of the ethanol extracts, essential oil, and major components of the species were evaluated. Antioxidant potentials of all extracts of this species were quite high in all studied antioxidant methods. Moreover, butyrylcholinesterase and elastase inhibitory capacities of ferruginol, the major component ofS. hypargeiaroots, were notable. For these reasons, this species has a high potential for food and pharmaceutical industries. Practical applications This new GC-MS method was applied toS. hypargeiaFisch. & C.A. Mey. and it indicated that this species possessed high amount of ferruginol and lupeol, and that this species could be used for their natural sources. According to the results of the activity studies (antioxidant, anticholinesterase, tyrosinase, elastase, and cytotoxic), this method was used to exhibit which compound may be responsible for the activities. This developed and validated method could be easily applied to determine major/active/toxic secondary metabolites ofSalviaspecies which are used and/or could be used in pharmaceutical, cosmetic, and food industries.

    LC/MS-MS Analyses and in vitro anticancer activity of Tourneuxia variifolia extracts
    (Taylor & Francis Ltd, 2022) Zerrouki, Sara; Mezhoud, Samia; Yilmaz, Mustafa Abdullah; Yaglioglu, Ayse Sahin; Bakir, Derya; Demirtas, Ibrahim; Mekkiou, Ratiba
    Several Saharan plants, despite their abundance of natural compounds, have received little attention. In this study, the chemical composition of polar extracts of Tourneuxia variifolia Coss. (Asteraceae), an endemic species to Algerian Sahara, was investigated and their anticancer activity was evaluated in vitro. The phytoconstituents of both ethyl acetate (EtOAc) and n-butanol (n-BuOH) extracts were screened using LC/MS-MS technique. The anticancer activity of the above extracts was measured against human cervical adenocarcinoma (HeLa) cell line. The LC/MS-MS analyses results revealed that twenty-seven phytochemicals in EtOAc extract and twenty-three in n-BuOH extract were identified and quantified from which isoquercetin and astragalin were the most present. Moreover; the EtOAc extract was found to have a strong anticancer activity (IC50: 46.797 +/- 0.060 mu g/mL). These findings identified T. variifolia as a potential plant exhibiting anticancer properties.
