Results of principal component analysis (PCA) of ¹H NMR spectra of hemolymph samples.

<p>PCA score plots (A) obtained with ^<b>1</b>H NMR spectra of the 0.25% DNJ group and control group (R^<b>2</b> = 0.712, Q^<b>2</b> = 0.64, ■control group, ●0.25% DNJ group) and coefficient-coded loading plots (B). PCA score plots (C) obtained with ^<b>1</b>H NMR spectra of the 0.25% DNJ group, mixture group, and control group (R^<b>2</b> = 0.858, Q^<b>2</b> = 0.636, ■control group, ●mixture group, ▲latex group) and coefficient-coded loading plots (D).
