The results showed that forty compounds were found and thirty five compounds were identified from shading cultivars; thirty compounds were found and twenty-eight compounds were identified from open field cultivars; thirty-six compounds were found and thirty-four compounds were identified from protected cultivars. the relative contents of constitutes were determined by area normalizing method. Six kinds of fatty acid were found from shading cultivars, the amount accounting for 71.44% in all the volatile oil; five kinds of fatty acid were found from open field cultivars, the amount accounting for 16.94% in all the volatile oil; six kinds of fatty acid were found from protected cultivars, the amount accounting for 52.87% in all the volatile oil. Considering from the variety and content of volatile oil, shading cultivars is the befitting cultivated mode.
