    Chemical Composition of Different Parts of the Vitex agnus-castus L. Essential Oils and Their In-Vitro Cytotoxic Activities

    The 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.

    Design Of A Burn Treatment Ointment Containing Herbal Bioactives
    (2024-05-15) Alğın Yapar E.; Gökçe E. H.; İnal E.; Ulusoy Ş.; Çankaya İ. İ.; Kartal M.; İNAL, EBRAR; ULUSOY, ŞEYMA; KARTAL, MURAT
    In this study, it was aimed to develop a burn treatment ointment consisting of herbal ingredients, which combination and synergistic effects had not been evaluated together in a formula before. In this regard, herbal ingredients were determined according to their cell proliferation, anti-inflammatory, antioxidant and astringent activities in light of a comprehensive literature review, and then eight ingredients were selected and divided into two groups. First group formulations were prepared by St. John\"s wort oil (Hypericum perforatum L.), bitter melon seed olive oil macerate (Momordica charantia L.), calendula olive oil macerate (Calendula officialis L.), horse chestnut fruit olive oil macerate (Aesculus hippocastanum L.) and second group formulations were prepared by Golden herb flower olive oil macerate (Helichrysum italicum Roth G.), chamomile flower olive oil macerate (Matricaria recutita L.), fenugreek seed oil (Trigonella foenum graecum L.) and grape seed oil (Vitis vinifera L.) as phytoactive ingredients in various amounts, and white beeswax (Cera alba) and vaseline mixture was used in both groups as ointment bases in various amounts to perform optimization of ointment formulations. At the end of preliminary studies, four formulas were selected to evaluate by rheology, spreadability and texture analysis for physical-mechanical characteristics and in vitro scratch assay on cell culture were performed to evaluate the wound healing efficacy of the formulas. The results showed that the ointment belonging to the second group, containing high concentrations of everlasting flower macerate, chamomile flower macerate, fenugreek seed oil and grape seed oil, had the best cell proliferation-wound closure activity. The effectiveness of this formula was examined in an in vivo mouse burn model, and it was observed that it provided more successful wound healing than the control group.
