“…Comparing our results with the data available for the EO of Algerian T. luteum subsp. flavovirens, more differences were observed since τ-cadinol (16.33%), caryophyllene oxide (13.23%), eudesma-4(15), 7-dien-1.β.-ol (7.64%), and β-pinene (6.77%) have been reported as the most abundant constituents [25]. EOs obtained from the plants from both regions.…”

Essential oils (EOs), the odorous and volatile products of a plant’s secondary metabolism, have wide applications in folk medicine, in food flavoring and preservation, and in fragrance industries. The aim of this study was to analyze the chemical composition of the EO from the aerial parts (including the inflorescences) of wild Teucrium luteum subsp. flavovirens from Tunisia. The EO obtained by the hydrodistillation of air-dried plant material in a Clevenger-type apparatus was analyzed using gas chromatography coupled with mass spectrometry (GC-MS). Fifty-three components representing 83.9% of the total constituents were identified. The EO of T. luteum subsp. flavovirens is characterized by the presence of β-elemol (7.2%), (+)-α-pinene (6%), β-eudesmol (5.5%), guaiol (4.2%), α-bisabolol (4.2%), and β-caryophyllene (4.1%) as principal chemical components. In vitro (DPPH and β-carotene bleaching assays), it showed significantly higher radical scavenging and antioxidant properties than the reference compound, BHT. To the best of our knowledge, this is the first report describing the composition and antioxidant properties of the EO from Tunisian T. luteum subsp. flavovirens. Our preliminary data will help to valorize this potentially useful plant species from Tunisia and represent a starting point for further studies on its volatile fraction.

Background:: Glioma is the most common and devastating brain tumor. In recent years, doxorubicin (DOX) is one of the drugs used in the treatment of gliomas, but it has side effects and poor clinical outcomes. Therefore, the delivery of drugs to the tumor site by targeted transport is a new approach to tumor treatment. Objective:: This study focuses on the anti-tumor effects of GFAP-modified drug-carrying liposomes loaded with DOX (GFAP-DOX-LPs) on gliomas. Method:: GFAP-DOX-LPs were prepared by solvent evaporation method. After characterization analysis of GFAP-DOX-LPs, the encapsulation efficiency, the drug loading capacity and in vitro release performance were determined. Then, the MTT method was used to investigate the cytotoxicity and proliferative behavior of U251 and U87 cell lines. After that, flow cytometry was used to investigate the effect of the drug administration group on tumor cell apoptosis. Eventually, the anti-tumor activity was tested in vivo. Results:: The average particle size of GFAP-DOX-LPs was determined to be 116.3 ± 6.2 nm, and the average potential was displayed as 22.8 ± 7.2 mv. Besides, the morphology of the particle indicated a spherical shape. The encapsulation rate and drug loading were calculated and determined, which were 91.84 ± 0.41% and 9.27 ± 0.55%. In an acidic medium, the DOX release rate reached about 87%. GFAP-DOX-LPs could target glioma cells with low cytotoxicity and inhibit glioma cell proliferation with high efficiency, resulting in promoting apoptosis. The anti-tumor effect of GFAP-DOX-LPs was significantly enhanced. At the same time, the number of GFAPpositive cells in tumor tissues was significantly lower after treatment. Therefore, the overall survival time could be significantly prolonged. Conclusion:: The prepared GFAP-DOX-LPs had good targeting and glioma cell inhibition ability. This demonstrated the promising application of the prepared liposomes in tumor targeting, especially in the field of targeted drug delivery for the treatment of brain tumor.
