Figure 2: The principal component analysis result of essential oil of Atractylodes rhizome. The green point means the samples from Atractylodes chinensis; the blue point means the samples from Atractylodes japonica; the red point means the samples from Atractylodes lancea. The closer the points on the graph are, the more similar their chemical composition is
