Research ArticleOpen accessIn the abstractComparative Phytochemical Analysis of Hydrodistilled Essential Oils of Scots Pine (Pinus Sylvestris L.) Needles From Central KazakhstanKuralay Tuleshova, Margarita Ishmuratova, Asanali Aynabayev et al.This study presents a detailed phytochemical investigation of hydrodistilled essential oils extracted from the needles of Pinus sylvestris (Scots pine), collected from fifteen natural populations located in the Karaganda and Ulytau regions of Central Kazakhstan. The extraction was performed using hydrodistillation with hexane as a co-solvent, and the chemical composition of the oils was subsequently analyzed using gas chromatography–mass spectrometry … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 28 Nov 2025 · 2,696 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhytochemical Composition, Antibacterial, and Antioxidant Properties of Foeniculum vulgare Essential OilSaif M. Dmour, Saqr Abushattal, Sultan Ayesh Mohammed Saghir et al.This study intended to inspect the phytochemical composition and bioactivity of Fennel (Foeniculum vulgare) Seed Essential Oil (FSEO) from Jordan. The EO was extracted via hydrodistillation from air-dried samples with 4.42% (v/w) yield. Twenty compounds, constituting around 98.5% of the EO were identified using Gas Chromatography-Mass Spectrometry (GC-MS). Estragole (47.15%) and Anethole (36.2%), appeared as predominant oxygenated monoterpenes compounds in … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 1 Aug 2025 · 4,638 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Toolkit Approach for Carbon Capture and Storage in Offshore Depleted Gas FieldRaj Deo Tewari, Tan Chee Phuat, Mohd Faizal SedaralitFossil fuels are considered a dependable, cost-effective, and efficient energy source and their utilization has resulted in tremendous growth for humanity. However, it has its downside also. Experts are of the view that present energy systems are unsustainable due to their detrimental impacts on the environment. Oil and gas producers are charged that their infrastructure, utilization of materials and technologies … …American Journal of Environmental Sciences, Vol. 19, Issue 1 · 17 May 2023 · 6,196 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExtraction Optimization of Essential Oil from Medicago hispida and Preliminary Inhibitory Mechanism Against Escherichia coliXiulan Chu, Qianfeng Chen, Tong Wang et al.In this study, the extraction optimization, characterization, antioxidant evaluation and preliminary inhibitory mechanism against Escherichia coli of the essential oil from dried Medicago hispida (EOMH) were explored to uncover the pending questions that had been raised in our previous work and to enlarge the industrial potential of EOMH production. The optimal parameters for EOMH extraction were: Extraction time of 7 … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 5,789 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Efficient Thermal Conversion Technologies and HHV from Compositional Characteristics of Cassava Peelings, Plantain Peelings and Corn CobsSamomssa Inna, Oumarou Amadou Amadou, Jiokap Nono Yvette et al.The understanding of compositional characteristics permits to predict the efficient thermal conversion technologies and Higher Heating Value (HHV). Although HHV can be determined directly, many models have been proposed for HHV prediction. They are based on proximate, ultimate, and structural analysis and require much data collected. The present work assesses to predict efficient thermal conversion technologies and HHV of the … …Energy Research Journal, Vol. 13, Issue 1 · 27 Dec 2022 · 10,157 accessesView PDF Cite
