One of the prerequisites to ensure the clinical efficacy and safety of volatile oils is to ensure the quality stability and uniformity. On the one hand, the quality of the essential oils of traditional Chinese medicine will be different because of the position, place of origin and harvest period of medicinal plants, on the other hand, the processing technology such as extraction technology and processing method, which is easy to cause the difference in the oil yield and chemical composition of the volatile oil, may also affects the quality, and then affects the curative effect. Therefore, controlling the quality stability and uniformity of volatile oils is one of the key points to ensure the efficacy of volatile oils. In this paper, the quality difference of volatile oils caused by different processing techniques was analyzed from the aspects of oil yield, appearance character, composition type and main component content, in order to provide reference for the development of volatile oil products and establishment of quality standard.
