Quantitation results of nine icariin analogues in E. pubescens leaves at five growth stages: Full flowering stage (FF), peak seed set stage (PSS), ripening stage (RS), and two timepoints of harvest stage (HS). The observation dates were the same as described in Figure 1. * p < 0.05 and ** p < 0.01, *** p < 0.001 and **** p < 0.0001 meant significant difference of the measurement at the indicated stage compared with E. pubescens leaf at FF stage. The contents were calculated per gram dry weight. (A) epimedin A; (B) epimedin B; (C) epimedin C; (D)icariin; (E) baohuoside I; (F) baohuoside I; (G) sagittatosides A; (H) sagittatosides B; (I) icaritin; (J) total content of nine analytes.
