Figure 2From: Genetic variation and metabolic pathway intricacy govern the active compound content and quality of the Chinese medicinal plant Lonicera japonica thunb Metabolic profile differences between flower buds of FLJ and rFLJ as detected based on PCA of GC-MS and HPLC data. (A) PCA of metabolic profiles based on GC-MS analysis (n = 3). (B) PCA of metabolic profiles based on HPLC analysis (n = 5). Y1–Y5, FLJ samples; R1-R5, rFLJ samples. Distinct metabolic profiles that correspond to a particular species are circled in (A) and (B). PCA analyses were performed by using the SIMCA-P + (12.0.0.0.0) program (Umetrics AB, Tvistevdgen 48 Umea 907 19, Sweden). p [1] is the first principal component, and p [2] the second principal component.Back to article page
