Anthracnose and crown-rot postharvest diseases of banana fruit are responsible for major postharvest losses of the fruit. For natural control of these diseases, in vitro antifungal activity of cassia and holy basil essential oils was evaluated by disc volatilization method. Cassia essential oil at 6 μL per plate exhibited 100% growth inhibition of both the causative fungal pathogens, namely Colletotrichum musae and Lasiodiplodia theobromae. Holy basil essential oil was capable of completely inhibiting the growth of L. theobromae at 6 μL per plate, whereas it could inhibit C. musae up to 96% at 10 μL per plate. Molecular docking and conceptual DFT studies have been performed to ascertain the components of essential oils responsible for antifungal activity based on their binding affinities to chitin synthase protein and chemical behaviour. Components, such as eugenol, cinnamyl acetate, caryophyllene, humulene and trans-calamenene, may most likely be responsible for high activity of the tested essential oils as per the in silico results.

香蕉果实的炭疽病和冠腐病导致果实的主要收获后损失。为了自然控制这些疾病，通过圆盘挥发法评估了决明子和圣罗勒精油的体外抗真菌活性。每板6μL的决明子精油对两种致病性真菌病原体（即炭疽菌（Colletotrichum musae）和Lasiodiplodia theobromae）均具有100％的生长抑制作用。每盘6μL的圣罗勒精油能够完全抑制L. theobromae的生长，但是可以抑制mus。musae每板10μL时高达96％。已经进行了分子对接和概念性DFT研究，基于它们与几丁质合酶蛋白的结合亲和力和化学行为来确定负责抗真菌活性的精油成分。根据计算机分析结果，诸如丁子香酚，醋酸肉桂酯，石竹烯，腐殖烯和反式卡拉曼烯等成分很可能是导致被测精油高活性的原因。
