Figure 2. (A) The ABTS radical scavenging activity of bromelain. The ABTS radical scavenging ability was calculated as (%) = (1 – sample A734nm/control A734nm) x 100. (B) The DPPH radical scavenging activity of bromelain. The DPPH radical scavenging ability was calculated as (%) = (1 – sample A515nm/control A515nm) x 100. (C) The hydrogen peroxide scavenging activity of bromelain. The hydrogen peroxide scavenging ability was calculated as (%) = (1 – sample A230nm/control A230nm) x 100. (D) The superoxide dismutase (SOD)-like activity of bromelain. The SOD-like ability was calculated as (%) = (1 – sample A420nm/control A420nm) x 100. All data are expressed as mean ± standard deviation (n = 3). P < 0.05, compared to the positive control : Medicinal Effects of Bromelain (Ananas comosus) Targeting Oral Environment as an Anti-oxidant and Anti-inflammatory Agent : Science and Education Publishing
