Figure 8

Hierarchical cluster analysis of the 3–7 year ginseng stems and leaves based on their volatile compounds. Note: ginseng stems and leaves on the 3rd year (3.1, 3.2, 3.3, 3.4, 3.5, and 3.6), on the 4th year (4.1, 4.2, 4.3, 4.4, 4.5, 4.6), on the 5 th year (5.1, 5.2, 5.3, 5.4, 5.5, and 5.6), on the 6th year (6.1, 6.2, 6.3, 6.4, 6.5, and 6.6), and on the 7th year (7.1, 7.2, 7.3, 7.4, 7.5, and 7.6).
