To optimize extraction process of volatile oil from flower of Gomphrena globosa and to analyze its chemical compo-sitions, the essential oils were extracted from Gomphrena globosa by microwave-assisted extraction (MAE). Distillation time, solid-liquid ratio, microwave power were investigated with extraction ratio of volatile oil. Extraction technology of volatile oil from flower of Gomphrena globosa was optimized by orthogonal test. Chemical compositions of the volatile oil were analysed by gas chromatography-mass spectrometry (GC-MS). The amount of the components from the essential oil were determined through normalization method. The essential oils were identified with Wiley and Nist05 mass spectrum atlas. Optimal extraction process of volatile oil was as follows: solid-liquid ratio 1:14 and distillation time 4 h. Under optimal extraction conditions, yield of volatile oil was 1.34%. There were 33 components composing of about 98.19% of the total essentials separated and i-dentified from Gomphrena globosa. by MAE. The study will provide scientific basis for the further exploration and utilization of Gomphrena globosa.
