Distribution of ginsenosides in leaf, stem, petiole, lateral root, and main root samples of P. ginseng at different growth stages. Heat map visualization of relative differences of ginsenosides in different growth stages of five parts. a Content of each ginsenoside, normalized for linkage hierarchical clustering. Each part type is visualized in a single column, and each ginsenoside is represented by a single row. Red indicates high relative abundance; green is low relative abundance (see color key above the heat map). b Score plot for principal component analysis. Negative values are below the average
