However, an increasing failure in treatment is observed due to resistance developed to these drugs. For this reason, alternative drugs have been investigated, especially by using natural products. In our study, the anti-T. vaginalis activity of the Origanum majorana essential oil (OMEO), which is a Cyprus endemic plant, and its synergistic effect with metronidazole were investigated. The essential oil was extracted through hydrodistillation of the dried flowering tops of the plant. Gas chromatography and mass spectrometry (GC-MS) analyses were performed using the Agilent 5975 GC-MSD system. L929 mouse fibroblast cell line was used to determine cytotoxic activity. Two clinical strains and one metronidazole-resistant T. vaginalis standard strain were used. LC₅₀, and MLC (minimum lethal concentration) values of OMEO and metronidazole were determined by the broth microdilution method in vitro in aerobic and anaerobic conditions. The combination of OMEO with metronidazole was investigated against all strains by the checkerboard method. The major compounds in the OMEO content were determined as cis-sabinene hydrate (29.1%) and terpinen-4-ol (19.6%). In cytotoxic analyses, it was observed that the cell viability remained stable at low doses. OMEO is effective against all three T. vaginalis strains. There is a significant difference between the IC₅₀ averages at the 24^th and 48^th hours (333.03 µg/mL and 226.43 µg/mL, respectively) in aerobic conditions (p=0.003). In addition, there is a statistically significant relationship between the results of the 24^th and 48^th hours (348.77 µg/mL and 238.80 µg/mL, respectively) in the anaerobic conditions (p=<0.0001). In general, OMEO has been shown to have a synergistic effect with metronidazole. In conclusion, we believe that OMEO is a potential natural agent that can be particularly used in the treatment of protozoan infections, including T. vaginalis.</p>","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"75 2","pages":"169-179"},"PeriodicalIF":1.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146100368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fatty acid analysis revealed that PSO was rich in polyunsaturated fatty acid (PUFA), predominantly alpha-linolenic acid (omega-3), while SSO contained higher levels of monounsaturated fatty acid (MUFA) and linoleic acid (omega-6). The blended oil exhibited intermediate characteristics, with an improved omega-6:3 ratios (1.02:1) relative to SSO (158.64:1) and PSO (0.29:1).

The challenges faced in the production of biodiesel from this third-generation lipids lie in the efficient extraction techniques and production costs. This study aimed to optimise extraction techniques to enhance lipid recovery from macroalgae. Six macroalgal species from the northwest coast of Aceh, Indonesia, were initially screened to evaluate their lipid yields using the Soxhlet extraction (S) method. Caulerpa taxifolia was selected for further optimisation based on its high lipid yield and favourable fatty acid profile, consisting of 85.8 % palmitic acid (C16:0) and 14.2 % myristic acid (C14:0). Various extraction methods were tested, including ultrasonication (S), enzymatic extraction (E), and combinations of ultrasonication-Soxhlet extraction (US), enzymatic-ultrasonication (EU), enzymatic-Soxhlet extraction (ES), and enzymatic-ultrasonication-Soxhlet extraction (EUS). The ES method produced the highest lipid yield of 21.5 %, a 15-fold increase compared to that of the S method alone. Physicochemical analysis of the extracted lipids showed properties suitable for biodiesel production, although further refinement is required to fully meet the quality standards. This study demonstrates the potential of optimised extraction techniques to significantly enhance lipid recovery from macroalgae, thereby contributing to the development of sustainable marine-biofuel resources.

HST-NPs (1 % HST) were prepared using bead milling treatment and various additives (mannitol, parabens, methylcellulose, 2-hydroxypropyl-Β-cyclodextrin), and quantification of HST in samples was performed using high-performance liquid chromatography. HST in both suspensions HST-NPs (with bead milling) and HST-MPs (without bead milling) was in the crystalline state, and the mean particle size of HST-NPs was 174 nm. Moreover, the transcorneal penetration of HST-NPs was higher than that of HST-MPs. HST levels in lenses treated with HST-MPs were below the limit of detection, whereas HST was detectable in HST-NP-treated rats at both 30 and 120 min post-instillation. In addition, instillation of HST suspensions prevented lens opacification in rats with selenite-induced cataracts; HST-NPs significantly inhibited lens opacification compared with HST-MPs. In conclusion, we successfully designed HST-NPs with high corneal penetration and effective delivery into the lens and demonstrated that instillation of HST-NPs significantly prevented lens opacification in a selenite-induced cataract model compared with HST-MPs.

It was found that different levels of initial interfacial tension (γ₀) had a more pronounced effect on the particle size and uniformity of the emulsion.
