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

Figure 5 S-plot loading diagram of the model and Polygonatum kingianum groups’ mitochondrial samples in the negative and positive ion mode. Each point represents a variable that shows the biomarker that caused the difference between the model and Polygonatum kingianum groups. N: Negative; P: Positive.
