Figure 1: Discrimination of samples from Guangdong and Yunnan. (a) principal component analysis score plot of Amomi fructus samples from Guangdong and Yunnan. (b) Dendrograms of the hierarchical-cluster-analysis result. (c) Orthogonal partial least-squares discrimination analysis score plot showing the discrimination the metabolome of Amomi fructus from Guangdong and Yunnan (R2 = [0.0, 0.454], Q2 = [0.0–0.201]). (d) The discrimination between the samples from two locations by chance permutation test at 200 times
