Essential oil samples were extracted by hydrodistillation and analyzed byGC and GC-MS systems. The highest EO contents were obtained in the fresh plant (1.98%). followed by shade-drying (1.34 %) and oven-drying at 30 °C (1.20 %). The main components were citronellol (23.99-39.87%). gcraniol (4.15-17.09%). mcnthonc (4.48-8.34%). linalool (1.96-7.42%), P-caryophyllene (2.63-4.32%), geranyl tiglate (0.99-4.52%), citronellyl butyrate (0.53-5.31%) and cis-rose oxide (0.71-3.15%). The diying methods showed a marked impact on the constituents of the EO samples. The results demonstrat¬ed that drying the aerial parts of fresh geranium, and shade-drying and oven-drying at 30 CC were the best optimal methods to obtain the highest oil yield, and citronellol. geraniol, and linalool contents in the oil.eninfo:eu-repo/semantics/openAccessAttribution 3.0 United StatesChemical compositionCitronellolDiying methodsEssential oil yieldGeraniolRose-scented geraniumArticle74110.3989/gya.0226221N/AWOS:0009583189000042-s2.0-8515375419133311142
