Chemical Fingerprint Analysis for Discovering Markers and Identifying Saussurea involucrata by HPLC Coupled with OPLS-DA

Figure 3

The OPLS-DA models for classification of the Saussurea involucrata and adulterants (A), Saussurea involucrata and Saussurea orgaadayi (B), and haplotypes I and II of Saussurea involucrata (C). The data were generated using common patterns of the upper quartile (1) and median (2).
