Determination and comparison of volatile aroma compounds in fresh and dried leaves samples of citronella grass, lemongrass, and citronella incense products by micro-hydrodistillation

摘要: Summary In this study, micro-hydrodistillation (MHD) was conducted for the determination of volatile aroma compounds (VACs) in fresh and dried leaves citronella grass, lemongrass, incense products. Optimum extraction VACs achieved when extractions were performed at 100°C with 0.5 g sample 3 mL water 60 min. Maximum recovery using hexane (2 mL) as solvent. Six major extracted from grass identified citronellal, citronellol, neral, geranial, geraniol, eugenol. Geraniol predominant VAC neral lemongrass leaves. Eugenol not detected extract. The validated method provided good recoveries ranging 83.6 to 105.3% relative standard deviations 6.2 11.0%. results presented paper show that amount essential oils signif...
