Two post-harvest pathogens, P. aphanidermatum and B. theobromae, were selected to evaluate the
antifungal activity of the vapor components in I. verum essential oil as well as trans-anethole. Four
days after exposure, the volatile components diffusing from the medium containing 0.5 mg/mL of I.
verum essential oil inhibited the growth of P. aphanidermatum mycelia at a rate of 93.82%, and transanethole
at the same concentration in medium more greatly inhibited the mycelia growth (Figure 1).
Their IC50 values were determined as 0.23 mg/mL (Y = 4.386 X + 7.838, R = 0.989, where Y is the
inhibitory probit value, X is concentration logarithm of the sample in the medium, and R is correlation
coefficient) for the oil, and 0.20 mg/mL (Y = 4.045 X + 7.799, R = 0.983) for
trans-anethole, respectively.
