Figure 4: The partial least-squares discriminant 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 abscissa means the difference between the groups, and the difference within the group is seen on the ordinate
