Score plot of principal components (PC1 versus PC2) on the variables (absolute area of reference peaks) with Atractylodes samples from the methanol extracts. PC1 and PC2 represent 40% and 21% of the total variance, respectively. AC: A. chinensis Koidz.; AJ: A. japonica Koidz.; AM: A. macrocephala Koidz.
