In the study, antifungal and ochratoxin A (OTA) production inhibitory activities of essential oils (EOs) of , , , , and were reported on . EOs were obtained by hydrodistillation and GC-MS technique was chosen to deduce their chemical profile. Major chemical compounds in EOs of , and were (E)-cinnamaldehyde (35.81 %), ar-turmerone (46.13 %), eugenol (36.58 %), geranyl proprionate (18.93 %), and geranyl acetate (14.88 %), respectively. The EOs shown potent antioxidant activity by DPPH and ABTS assays. The EOs presented superlative antifungal activity against related to . The and EOs shown superlative antifungal activity related to other EOs. The and C. EOs completely inhibited the growth and OTA production of and at 1500 and 2500 μg/g in maize grains, respectively.
在该研究中,报道了丁香、姜黄、丁香罗勒、柠檬香茅和肉桂的精油(EOs)对赭曲霉的抗真菌及赭曲霉毒素A(OTA)产生抑制活性。通过水蒸馏法获得精油,并选用气相色谱-质谱联用(GC-MS)技术推断其化学组成。丁香、姜黄和丁香罗勒精油中的主要化学成分分别为反式肉桂醛(35.81%)、莪术烯(46.13%)、丁香酚(36.58%)、丙酸香叶酯(18.93%)和乙酸香叶酯(14.88%)。通过DPPH和ABTS法测定,这些精油表现出较强的抗氧化活性。这些精油对与赭曲霉相关的霉菌呈现出极高的抗真菌活性。丁香罗勒和肉桂精油相对于其他精油表现出极高的抗真菌活性。丁香和肉桂精油分别在玉米籽粒中1500和2500μg/g的浓度下完全抑制了赭曲霉和疣孢青霉的生长及OTA产生。
