Serum Metabolomics Study Based on LC-MS and Antihypertensive Effect of Uncaria on Spontaneously Hypertensive Rats

Figure 5

Multivariate analysis of untargeted metabolomics data. (a) OPLS-DA score plots of serum metabolic profiling of model group (1) and Uncaria group (2). (b) Loading plots constructed from the supervised OPLS-DA. (c) S-plot constructed from the supervised OPLS-DA. (d) VIP-score plots constructed from the supervised OPLS-DA. The loading plot, S-plot, and VIP plot were carried out to select distinct variables as potential biomarkers.
