Means within a column followed by the different letters, are significantly different at p < 0.05. Numbers in parentheses are the rates in comparison with control; “+” symbol shows promotion percentage over control, “−” symbol shows inhibition percentage over control. AI: Average Inhibition. *: significantly different (p < 0.05), ns: not significantly different.
