The study explores the efficacy of Cinnamomum glaucescens essential oil (EO) as insecticidal, antifungal, antiaflatoxin and antioxidant agent so as to recommend its application as plant based preservatives for food commodities. The study reports the chemical characterization of C. glaucescens oil and its 100% insecticidal activity against insect pest Callosobruchus chinensis on 12 h exposure and 98.74% oviposition deterrency at 0.15 μl/ml. The EO significantly inhibited growth and aflatoxin production by toxigenic strain of Aspergillus flavus LHP-10 at 4.5 and 3.5 μl/ml respectively. EO also showed appreciable antioxidant activity (IC(50) value=15.1 μl/ml), non phytotoxic nature on chickpea seed germination and in vivo potential as fumigant in food system providing 71.07% protection of chickpea samples from fungal contamination and 100% antifeedant activity against the insect invasion. The EO exhibited non-mammalian toxicity showing high LD(50) (3971.34 μl/kg) during oral toxicity on mice.
本研究探索了肉桂油（Cinnamomum glaucescens essential oil，简称 C. glaucescens oil）作为杀虫剂、抗真菌剂、抗黄曲霉毒素和抗氧化剂的功效，以推荐其作为基于植物的食品防腐剂的应用。本研究报告了 C. glaucescens 油的化学特性及其对昆虫害虫绿豆象（Callosobruchus chinensis）在 12 小时暴露下的 100%杀虫活性和在 0.15 μl/ml 时 98.74%的产卵驱避作用。该精油在 4.5 和 3.5 μl/ml 时显著抑制了产毒菌株黄曲霉（Aspergillus flavus LHP-10）的生长和黄曲霉毒素的产生。该精油还表现出明显的抗氧化活性（IC(50) 值为 15.1 μl/ml），对鹰嘴豆种子发芽没有植物毒性，并且在体内具有作为食品体系熏蒸剂的潜力，可使鹰嘴豆样品免受真菌污染的保护率达到 71.07%，并对昆虫入侵具有 100%的拒食活性。该精油表现出非哺乳动物毒性，在对小鼠进行口服毒性试验时，其 LD(50)（3971.34 μl/kg）值较高。
