Publication Metadata only Chemical Composition of Different Parts of the Vitex agnus-castus L. Essential Oils and Their In-Vitro Cytotoxic Activities(2023-12-01) İnal E.; Nath E. Ö.; Abudayyak M.; Ulusoy Ş.; İnan H. A.; Cicek M.; Kartal M.; İNAL, EBRAR; ULUSOY, ŞEYMA; KARTAL, MURATThe essential oil (EO) compositions and chemotypes of the important ethnomedicinal plantVitex agnus-castusL. flowers, leaves, and fruits collected from Türkiye (Balıkesir and İstanbul) were identified in the present study. Different parts of theV. agnus-castusEO’sin-vitrocytotoxic effects on the MCF-7 (human breast adenocarcinoma) and A549 (human lung carcinoma) human-origin cell lines were anaylzed in the current study. The composition of hydrodistiled EOs extracted from flowers, leaves, and fruits ofV. agnus-castuswere analyzed by GC–FID/MS. Monoterpene hydrocarbons and oxygenated monoterpene compounds were detected as the predominant component class of theV. agnus-castus. EOs extracted from Balıkesir region were defined as the \"α-pinene-1,8-cineole\" chemotype, while EOs extracted from İstanbul region were defined as the \"sabinene-1,8-cineole\" chemotype. Sesquiterpene hydrocarbons constituted more than 20% of the compounds in the EOs extracted from the flowers. To the best of our knowledge, this study is the first to analyze thein-vitrocytotoxic effects of flowers. This study is also the first to show thein-vitrocytotoxic effects of fruit, the most commonly used part of the plant, EO on the MCF-7 cell line. Balıkesir region’s EOs were observed as more potent -especially the purple flower’s IC50 is about 4.68 µg/mL on the MCF7 cell line- than İstanbul regions, which might be attributed to the higher amount ofα-pinene, caryophyllene, and limonene content. Our results indicated that theV. agnus-castusEOs, which containα-pinene, 1,8-cineole, caryophyllene, and limonene as major components, showed relatively high cytotoxic effects compared to the control groups on the MCF7 and A549 cell lines.Publication Metadata only Development of phytoactive essential oils-composed organogels against oral pathogens(2024-08-01) ALĞIN YAPAR E.; Gökçe E. H.; Şahiner A.; İNAL E.; ULUSOY Ş.; Souto E. B.; Akanoğlu B.; KARTAL M.; İNAL, EBRAR; ULUSOY, ŞEYMA; KARTAL, MURATGingivitis, one of the most common periodontal diseases, is the inflammation of the gingival tissues that causes swelling, tenderness, redness and bleeding. The treatment should contain anti-inflammatory, antibacterial, and antioxidant agents to decrease the risk of dental plaque formation and periodontal tissue damage in the inflammatory process. In line with the antibacterial, antifungal, and antioxidant effects of the geranium (Pelargonium graveolens L\"Hér.) herb, common sage (Salvia officinalis L.) herb, and mastic tree (Pistacia lentiscus L.) leaf, in this work we propose their use as active pharmaceutical ingredients of periodontal gels. The organogel formulations were produced either by microwave-assisted irradiation method or by the conventional approach (microwave-free), and further characterized for their physicochemical properties, antimicrobial efficacy and cell viability. Among them, the gel formulation containing 4 % geranium essential oil obtained by the conventional method was identified as the best candidate to be developed as an effective and safe alternative suitable for oromucosal applications.
