Untargeted UPLC-MS/MS Analysis-PCA (n = 5)

In the PCA analysis results, the column diagram on the left showed the explanation rate of variance of each principal component, and the distribution of the overall variance on each component could be observed. The scatter diagram on the right showed the projections of samples on first principal component (PC1) and second principal component (PC2). Points of different colors and confidence ellipses indicated different experimental groups. The hexagonal star in the ellipse indicated the central position, and the percentages in parentheses on the horizontal and vertical coordinates indicated the explanation rate of variance of each principal component.

(A) UNX VS control.

(B) 1/6NX VS control.

(C) UUO VS control.
