The percent relative enzyme activity (RA %) of porcine pancreatic α-amylase (PPA) on inhibition with different extracts. (a)Cold water extracts-CWE (b) Hot water extracts-HWE (c) Methanol extracts-ME (d) Isopropanol extracts-IPE (e) Methyl-tertiary-butyl-ether extacts-MTBE (f) Cyclohexane extracts-CHE of the listed plants. Pure porcine pancreatic α-amylase serves as control. The data is indicated as the mean ± SEM; (n = 3). The students F-test was used and the bars with different asterisks (***, **, *) show significant difference with respect to control (P < 0.05). 1 Control 2 A. vera 3 C. fistula 4 L. usitatisumum 5 M. alba 6 O. tenuiflorum 7 T. foenum.
