Kelussia odoratissimais known as an endemic and valuable spice plant. The effect of six different drying treatments (sun, shade, oven 45°C, oven 65°C, microwave and freeze drying) was studied on the color, essential oil content and chemical composition ofK. odoratissimaleaves. The essential oils were isolated from fresh and dried samples by a hydrodistillation method and analyzed using gas chromatography–mass spectrometry (GC–MS). The highest essential oil yield was obtained by shade drying (1.50%) followed by microwave (1.46%) and oven 65°C (1.43%)-drying methods. The major compounds ofK. odoratissimaoils were (Z)-ligustilide, (E)-ligustilide andcis-3-butylidene phthalide. Drying treatments significantly increased (Z)-ligustilide compared with the fresh one. In this study, (Z)-ligustilide ranged from 48.67% in sun-dried samples to 68.3% in 45°C oven-dried ones. For color analysis, shade drying possessed the highesta*/b* value, followed by microwave and oven 45°C. Results showed that shade drying at ambient temperature significantly increased the essential oil yield and (Z)-ligustilide with acceptable color quality. Finally, shade and oven drying (<50°C) methods were introduced to produce appreciable essential oil yield, composition and color quality. [ABSTRACT FROM PUBLISHER]
