Abstract:
Cymbopogon and it's essential oil have medicinal, pharmaceutical, industrial, and cosmetic applications. In Sudan aqueous extracts of Cymbopogon leaves and spikes are traditionally used for nutritional and medicinal purposes. This study was conducted to investigate the yield percentage and chemical composition of Cymbopogon volatile oil. Samples of Cymbopogon Leaves and spikes were obtained from Northern Darfur and Gedaref states. Steam distillation was used for extracting cymbopogon leaves and spike oil. GC/MS spectroscopy was used for the analysis of the two extracted oil samples. The oil yield was (1.5%) for spikes and (1.67%) for the leaves.Forty eight components were identified in the spikes oil, dominated by Piperitone (35.96%), Elemol (20.45%), (+) - 2- Carene (8.18%), Guaiol (6.04%), ?-eudesmol (5.97%), ?-eudesmol (4.28 %), Bulnesol (3.14%), Limonene (1.44%) and ?-Eudesmol (1.37%). Leaves oil showed a presence of sixteen constituents, dominated by Piperitone (84.13%), (+)-2-carene (5.75%), d-Limonene (2.67%) and ?- terpineol (2.21 %). The chemical composition of the two oil samples may encourage the traditional use of Sudanese Marhabaib (Cymbopogon schoenanthus), for medicinal and nutritional, cosmetic, and flavoring purposes.
