بررسي كيفيت و تجزيه و تحليل GC/MS اسانس گياهان هومولوس لوپولوس، ملوا سيلوستريس و آويشن در مخلوطي از حلال‌هاي اتانول و هگزان

Quality Check and GC/MS Analysis Essential Oil of Humulus Lupulus, Malva Sylvestris and Thymus Plants in a Mixture of Ethanol and Hexane Solvents

The aim of this study was to investigate the chemical composition of medicinal essential oils of Humulus lupulus, Malva sylvestris and thymus. After collection, medicinal plants were essential oil extracted by water distillation (Clevenger design). Essential oil formation compounds were identified using gas chromatography-mass spectrometer (GC / MS). The results showed that each plant extract has different quantity and quality of active ingredients. In Humulus lupulus, the maximum percentage efficiency with 31.46% is related to petanoic acid and in Malva sylvestris and Thymus plants, it is related to 34.47% respectively and 39.25% is related to phenol. Therefore, the chemical compounds that had the highest percentage efficiency have many applications in the field of medicine and cosmetics, and those that have the lowest efficiency and are very low have the least use and were reported.
