Extraction Optimization, Preliminary Identification, and Bioactivities in Corn Silk

Figure 4

Different concentrations of corn silk ethanol extracts had different inhibitory effects on Bacillus subtilis. The criteria for antibacterial effects are as follows: diameter >20 mm means extremely effective, 15∼20 mm means highly effective, 10∼15 mm means moderately effective, 7∼9 mm means slightly effective, and absence of inhibition zones means ineffective.
