The melting fleshed peach is highly susceptible to infection by pathogenic fungi after harvested. Although synthetic preservatives could effectively reduce the spoilage, they normally will pose a threat to the environment and human health. The essential oils (EOs) was extracted from the three Chinese herbal medicines which were considered as a better natural substitute in the application of antifungal substance. Their chemical composition was analyzed by gas chromatography-mass spectrometry (GC-MS), and principal component analysis (PCA) was used to identify possible relationships between EOs composition and habitats. In vitro test, the significantly (P < 0.05) antifungal activity of these EOs against 6 pathogens was proved at 50 mu g/mL dosing concentration. Compound preparation of EOs (CP EOs) significantly (P < 0.001) reduced the decay index based on the optimized composition of three Chinese herbal medicine EOs through response surface methodology (RSM). CP EOs microemulsion (M-CP EOs) was developed to improve the bioavailability, which could significantly (P < 0.05) increase the antifungal activity compared with CP EOs. Consequently, these EOs could be considered for the production of natural preservative which reduced our dependence on the synthetic preservatives.
