[Objective] To study the chemical compositions and biological characteristics of essential oil from Cuminum cyminum L. planted in Hotan of Xinjiang Province. [Method] The essential oil was firstly extracted from seeds of Cuminum cyminum L. by steam distillation method, and then its chemical compositions were analyzed and identified by gas chromatography-mss spectrometry (GC-MS) and standard spectrum library. [Result] 48 chromatographic peaks were isolated from seeds of Cuminum cyminum L., of which 38 compounds that accounted for 98.55% of the total essential oil were identified. The most abundant compounds were cuminal (39.03%), 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 1.25 μl/ml. [Conclusion] The study could provide a scientific basis for further exploration and utilization of Cuminum cyminum L. planted in Hotan of Xinjiang Province.
