Figure 3.

Bar graph figure with three panels displaying phytochemical contents in roots, rhizome sections, stems, and leaves of Rhodiola crenulata, Intergrades, and Rhodiola fastigiata. Panel A shows total flavonoids, Panel B displays salidroside, and Panel C shows tyrosol content percentages. Each group is color coded, with labeled statistical differences using lowercase letters. Data highlights the highest total flavonoids in Rhodiola crenulata leaves, and varying salidroside and tyrosol distribution among organs and taxa, with some values marked as not detected.

Determination of total flavonoids, salidroside, and tyrosol in R. crenulata, intergrades and R. fastigiata. (A) Total flavonoid content; (B) Salidroside content; (C) Tyrosol content. Bars represent standard error (SE). Different letters indicate significant differences (P < 0.05).
