The oil was extracted by ethanol steam distillation method, the oil composition was analyzed by GC-MS.</p> <p><strong>RESULTS: </strong><em>Cymbopogon winterianus</em> stems are 15-35 cm long and 0.5-2 cm broad, with a rough, stiff, and thin texture, with prominent fibers on the top and bottom surfaces. It has a bitter and slightly spicy taste with a distinctive lemony aroma and was greenish yellow in hue with a blend of purplish-red colors. The upper and lower epidermis was examined under a microscope, which revealed sclerenchyma fibers, trichomes, parenchyma, calcium oxalate (rosette), cortex, stem pith, oil cells, stomata (Gramineae type), trachea (ladder and spiral thickening), and collenchyma. The water content was 7.16±0.72%, the water-soluble extractive value was 12.152±0.003%, the ethanol-soluble extractive value was 12.290 ±0.76%, and the essential oil content was 6.46±0.50%. Essential oil constituents were 6-octen-1-ol, 3,7-dimethyl-, formate; trifluoroacetyl-lavandulol; n-hexadecanoic acid; 9,12-octadecadienoic acid (Z,Z)-; oxacyclotetradecane-2,11-dione, 13-methyl-; palmitic acid vinyl ester; glycidyl palmitate; 9,17-Octadecadienal, (Z)-; glycidyl palmitoleate; 1,4-bis(trimethylsilyl)benzene; and cyclotrisiloxane, hexamethyl-.</p> <p><strong>CONCLUSION:</strong> The essential oil constituents and preliminary pharmacognostic evaluation of <em>Cymbopogon winterianus</em> stem can provide useful data for further phytochemical analysis, quality control, and standardization of <em>Cymbopogon winterianus</em>. Citronellyl formate detected as citral derivatives as the main compound in the ethanol steam distillation method.</p>}, number={A}, journal={Open Access Macedonian Journal of Medical Sciences}, author={Haerussana, Ayu Nala El Muna and Chairunnisa, Haura Fatona}, year={2022}, month={Apr.}, pages={1338–1346} }
