Mitochondrial metabolomic profiling for elucidating the alleviating potential of Polygonatum kingianum against high-fat diet-induced nonalcoholic fatty liver disease

Figure 4 Orthogonal partial least squares discriminant analysis score plots of the mitochondrial samples in the negative and positive ion mode. The four groups were significantly separated, suggesting remarkable differences in the metabolic state between them. PK: Polygonatum kingianum; N: Negative; P: Positive.
