A novel phenol-bound pectic polysaccharide from Decalepis hamiltonii with multi-step ulcer preventive activity

Figure 6 H⁺, K⁺-ATPase (A), Fourier Transform Infra-Red Spectroscopy (B), Reducing power (C) and Free radical scavenging activity (D) of SRPP. A: inhibition of H⁺, K⁺-ATPase only by SRPP (•) and not by other polysaccharides of Swallow root; SR water soluble polysaccharide (▪), SR Hemicellulose A (+), Hemicellulose B (□), SR alkali insoluble residue (◊) and inhibition by lansoprazole (o) a known blocker is also depicted in the figure; B: arrow at 1329 and 1145 cm^-1 indicate the presence of sulfonamide group in FTIR spectrum. Dose dependent antioxidant activity evaluated as reducing power ability (C) and free radical scavenging ability (D) indicates potential antioxidant activity by phenolics of SRPP.
