Fig. 7. Changes in saikosaponin content under drought stress. (A) Total saikosaponin content. (B) SS-a content. (C) SS-d content. (D) SS-c content. (E) SS-e content. (F) SS-f content. Shown are the means ± standard deviation (n = 9). The asterisk indicates a significant difference (p <0.05) between drought-stressed and control plants (Duncan's single-factor variance analysis).
