The invention relates to a capillipedium parviflorum essential oil, which is separated from capillipedium parviflorum inflorescence. In the separating process, the inflorescence of the capillipedium parviflorum is used as raw materials. The faint yellow oily essential oil concentrated solution is acquired by using the conventional method which includes the steps of collecting, washing, normal-pressure steam distillation, oil-water separation and drying with anhydrous sodium sulfate. The oil yield is 0.8% to 1%. The dried essential oil is determined by using a capillary gas chromatograph-mass spectrometer. The result is that the type number of the compound is 22 which is 92.75% of the whole oil mass, wherein the primary component is 1-nonene-4-alcohol, 4-hendecanone, 4-undecanol, and 2,4-dimethyl-3-pentyl acetate. The essential oil is high-class pure natural essential oil which is fragrant, stable in fragrant, good in inducing property, free from stimulation to skin, non-toxic and safe, and is capable of being used for preparing cosmetics, used as food additives, tobacco essence, washing agent essence and officinal essence.
