doi: 10.3390/plants11192465

Figure Lengend Snippet: Kinsenoside, isoquercitrin, and astragalin contents in A. roxburghii PLBs and plants. ( a ) HPLC chromatograms of kinsenoside contents; 1–6 correspond to 0–5 weeks of culturing, respectively, 7 corresponds to the kinsenoside standard, and 8–11 correspond to the roots, stem, leaf, and whole plant, respectively. The asterisk indicates the kinsenoside content was significantly different from that of roots ( p < 0.05). ( b ) Kinsenoside contents in PLBs and plant tissues; the numbers on the x-axis refer to the number of weeks. ( c ) Isoquercitrin (I) and astragalin (II) contents in different tissues of A. roxburghii plants; 1–6 correspond to 0–5 weeks of culturing, respectively, 7 corresponds to the isoquercitrin (I) and astragalin (II) standards, and 8–11 correspond to the root, stem, leaf, and whole plant, respectively. Arrows indicate the peak isoquercitrin and astragalin levels.
