Teucrium poliumis widely used in Algerian folk medicine as to treat wounds. The aim of this study was to evaluate the chemical composition, antioxidant and wound healing properties of Teucrium polium essential oil. The composition was obtained by a combination of GC-FID and GC-MS analyses. The antioxidant activity was evaluated by in vitro assays (total antioxidant capacity, DPPH and bleaching of β-carotene). The in vivo wound healing potential of an ointment containing 10% of T. polium essential oil was investigated. The main components were in this order: β-pinene, germacrene, α-pinene, myrcene, limonene, bicyclogermacrene, trans-β-guaiene, spathulenol and β-bourbonene. Teucrium polium essential oil displayed a moderate antioxidant activity. The in vivo experiments showed that 10% OEO accelerated the wound healing process in comparison with controls. This study provides a scientific rationale for the use of Teucrium polium essential oil in the treatments of wounds.

The aims of the study were to evaluate the wound-healing properties in an in-vivo model of the essential oils from Algerian and Italian Pistacia vera L. oleoresins. The essential oils (EOs) were obtained by hydrodistillation of oleoresins from the trunk of plants. They were analyzed by GC-FID and GC-MS, α-pinene was the main constituent of both EOs. The wound-healing potential of P. vera EOs was investigated using an excision wound model in rabbits. The EOs were mixed with petroleum jelly to obtain a topical ointment with a final concentration of 5%. The percentage of the evolution of wound contraction was calculated and histological sections of tissues were examined. Both preparations possess wound-healing activities comparable to that of the reference drug Cicatryl-Bio. Some EOs exhibit a wound-healing potential suggesting that they could find a place in modern therapy.

Background: Pituranthos scoparius (Apiaceae), commonly known in Algeria as “Kozah”, is a medicinal plant traditionally used for various therapeutic purposes. However, its potential as a source of antiproliferative agents and its underlying molecular mechanisms remain poorly characterized. Purpose: This study aimed to investigate the antiproliferative potential of P. scoparius through an integrated strategy combining phytochemical profiling, in vitro evaluation, and computational approaches, with particular emphasis on its activity against key cancer-related pathways. Study Design: An integrated experimental–computational study was performed to explore the multitarget antiproliferative profile of P. scoparius extracts. Methods: Phytochemical characterization was carried out using LC-MS/MS and GC-MS/MS to identify the major bioactive constituents. Antiproliferative activity was assessed in vitro against human colorectal (HT-29) and hepatocellular carcinoma (HepG2) cell lines using the MTT assay. Molecular docking studies were conducted on selected major metabolites against relevant oncogenic targets, including PI3Kα, mTOR, COX-2, and BCL-2, to investigate potential mechanisms of action. Machine learning approaches were further employed to support the prediction of multitarget antiproliferative activity. Results: Chlorogenic acid and trans-ferulic acid were identified as the predominant phenolic compounds, while α-pinene was the major constituent of the essential oil. Both preparations exhibited significant dose- and time-dependent antiproliferative effects, with the essential oil showing enhanced cytotoxicity (IC₅₀ up to 35.4 µg/mL). In silico analyses revealed strong binding affinities of key metabolites toward critical oncogenic proteins, particularly within the PI3Kα/mTOR signaling pathway. Machine learning predictions further supported a multitarget antiproliferative profile. Conclusions: P. scoparius represents a promising source of natural compounds with multitarget antiproliferative potential. The combined experimental and computational findings provide mechanistic insights into its activity and support its relevance within the context of natural product-based cancer therapy, highlighting its potential for further preclinical development.
