Table 1. ACE-inhibitory effect of the RP-HPLC fractions and IEF sub-fractions.

RP-HPLC fractions	ACE-inhibitory activity (%)	IEF sub-fractions	ACE-inhibitory activity (%)
10	31.83±1.57^c	11	64.49±0.417^b
11	29.67±0.29^d	9	69.21±0.33^a
17	28.81±0.85^d	1	43.92±0.13^e
18	43.50±0.78^a	2	60.43±0.78^c
20	35.45±0.92^b	9	52.11±1.13^d

Results are expressed as mean ± SD of triplicate determinations. Means of ACE-inhibitory activity (%) which carry different superscript letters are significantly different at P ≤ 0.05.
