Volatile Components’ Variation Analysis on Ginseng Stems and Leaves at Different Growth Ages by HS-SPME-GC-MS

Figure 7

Potential biomarker analysis: (a) the identified differential metabolite heatmap between GSL3 and GSL4 horizontally represent each sample in the two groups and longitudinally represent the differential metabolites in each sample. (b) Correlation heatmap of the differential metabolites among GSL3 and GSL4; red means positive correlation and green means negative correlation. (c) Intensity changes of 1-cyclohexene-1-carboxaldehyde, 2, 6, 6-trimethyl- from GSL3 to GSL7. (d) AUC curve of 1-cyclohexene-1-carboxaldehyde, 2, 6, 6-trimethyl-.
