Fig 1: ACE inhibitory effects of mulberry root bark and twig extract fractions. The ACE inhibitory rate (%) of different root bark fractions at 10–100 μg/mL (A) and cultivars at 100 μg/mL (B) were compared. The efficacy of the inhibition is categorized by the fraction or the source (root vs. twig). Abbreviations are background control (BC) and inhibitor control (IC). Statistical significance is denoted by different letters above the bars (p < 0.05), n = 3.
Fig 2: Comparative ACE inhibition by single compounds derived from mulberry. The ACE inhibitory effects of single compounds at 10 μg/mL (A) and kuwanons according to the density (10–100 μg/mL) (B) were compared. Abbreviations ae background control (BC), inhibitor control (IC), and not applicable (NA). The differences between groups were compared and the significance levels marked accordingly using different letters (p < 0.05), n = 3.
