Table 1.

The inhibitory ratio on dipeptidyl peptidase IV (DPP-IV) by ultrafiltrate of Lapsang souchon from different membranes (n = 3). General linear model (GLM) followed by Ryan–Einot–Gabriel–Welsch’s (REGWQ’s) multiple range test. Means with different letters (a, b, c) have significant difference (p < 0.05).

Membrane (kDa) Total Phenols (μg/mL) Inhibition of DPP-IV Activity (%)
50 49.2 ± 0.83 a 75.5 ± 0.47 a
10 42.8 ± 0.59 b 73.8 ± 0.54 a
5 42.5 ± 0.42 b 75.7 ± 1.00 a
1 30.7 ± 0.82 c 72.7 ± 2.57 a
