Figure 1

Degradation of phenylethanoid glycosides under different conditions. The effect of temperature on the contents of TPG in OFE (A), salidroside in OFE (B), acteoside in OFE (C), salidroside standard (D) and acteoside standard (E) at pH 6.0 in the dark; the effect of light on the contents of TPG in OFE (F), salidroside in OFE (G), acteoside in OFE (H), salidroside standard (I) and acteoside standard (J) at pH 6.0 at 20 °C; the effect of pH on the contents of TPG in OFE (K), salidroside in OFE (L), acteoside in OFE (M), salidroside standard (N) and acteoside standard (O) at 20 °C in the dark. TPG, total phenylethanoid glycoside; OFE, O. fragrans var. thunbergii flower extracts.
