^aResults are expressed as mean percentage ± S.E.M of three observations in each group; (% inhibition of AM); (% inhibition of FF).

Amylase inhibitory activity (%) was defined as the percentage decrease in maltose production rate over the control (without extract).

*Values significantly different (P < 0.05) from the control in each group without the extract added.
