Effect of crude extract and n-BuOH and aqueous residual fractions on the disaccharidases
We observed that CE, BF and ARF were able to reduce slightly maltase specific activity at the maximal dose tested (1500 µg/mL) after 5 min of in vitro incubation when compared with the basal group (Figure 4). The maximum effect was observed for BF which inhibited 20% of maltase activity, while this inhibitory effect was around 13% and 14% for the CE and ARF, respectively. On the other hand, none of the treatments affected the sucrase and lactase activity at any concentration tested (data not shown).
