MethodsCymbopogon citrates was dried by drying in the sun, drying in the shade and oven drying at 40℃. Volatile oil was extracted by steam distillation. Chemical constituents in the volatile oil were analyzed by GC-MS and the antioxidative activities were determined by ferric reducing antioxidant power (FRAP method).Results Extraction rate of the volatile oil fromCymbopogon citratesunder the environment of freshness, sun drying, shade drying and oven drying at 40℃ were 0.25%, 1.21%, 1.19% and 1.17%, respectively; after dried by different methods, main constituents and antioxidative activities of the volatile oil fromCymbopogon citrates were basically same.
