Study of Saponin Components after Biotransformation of Dioscorea nipponica by Endophytic Fungi C39

Figure 3

Score plot (a) and corresponding loadings plot (b) output from the principal component analysis. Note. 1: Dioscorea nipponica crude drug, 2: 15 d fermentation sample, 3: 20 d fermentation sample, 4: control drug, and 5: C39 fungi blank. Because some data were concentrated in the same area of 2–5, 3–3, and 3–4, the score plot data are not shown; therefore, the area of 2–5, 3–3, and 3–4 represents 2–1, 2–2, 2–3, 2–4, 2–5, 2–6, and 3–1, 3–2, 3–3, 3–4, 3–5, 3–6; the clustering situation is good.
