2-Heptanol inhibits by accelerating amino acid metabolism and retarding membrane transport.

During the postharvest storage of tomatoes, they are susceptible to infection by , leading to significant economic losses. This study evaluated the antifungal potential of 2-heptanol (2-HE), a volatile biogenic compound, against and explored the underlying antifungal mechanism. The results indicated that 2-HE effectively suppressed the growth of mycelia both and and stimulated the activities of antioxidative enzymes, including superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in tomatoes.
