Abstract

[Objective] To study the chemical compositions and biological characteristics of essential oil from Cuminum cyminum L.planted in Hotan.[Method] The essential oil was extracted from seeds of Cuminum cyminum L.by steam distillation extraction method and the chemical compositions were analyzed by GC-MS.[Result] Forty-eight compounds were detected,of which 38 compounds that accounted for 98.53% of the total volatile oil were identified.The most abundant compounds were: cuminal(39.03% of the total oil),1-methyl-2-isopropylbenzene(12.85%),3-caren-10-al(9.15%) and 4-ethyl-3-nonen-5-yne(8.28%).The Cuminum cyminum L.essential oil showed good antibacterial,sterilization and antioxidant activity.The MIC of essential oil against Staphylococcus aureus and Escherichia coli both were 1.25μl/ml.[Conclusion] The study provided scientific basis for further exploration and utilization of Cuminum cyminum L.
