概述
font-size:10.5000pt;mso-font-kerning:1.0000pt;">桔青霉素(citrinin, CTN)又叫做桔霉素,是一種由青霉菌屬和曲霉菌屬中多種真菌產生的天然代謝產物,可導致腎臟及肝臟損害,是桔青霉等的毒性代謝產物,主要污染大米。桔青霉素已被證實為肝臟的致突變原并且研究顯示其可能同時還是地方性巴爾干腎病和豬腎病的致病原。

mso-font-kerning:1.0000pt;">該
font-size:10.5000pt;mso-font-kerning:1.0000pt;">霉素在175 ℃干加熱時分解,形成毒性更強的桔青霉素H1和桔青霉素H2。

mso-font-kerning:1.0000pt;">此外,
font-size:10.5000pt;mso-font-kerning:1.0000pt;">桔青霉素經常與其它真菌毒素(例如黃曲霉毒素B1)一起出現,因為它們是同種真菌產生的。當這些真菌毒素同時出現時,其腎毒性作用疊加,幾種毒素互相增加協同作用。在2017年世界衛生組織研究機構公布,桔青霉素被列在三類致癌物質清單中
