伞菌氨酸
伞菌氨酸(英语:Agaritine,AGT),是一种存在于伞菌属真菌中的芳香联氨类真菌毒素[1]。其为α-氨基酸的苯肼衍生物。

分布
伞菌氨酸作为一种天然产物,其存在于伞菌属、白环蘑属和大环柄菇属下至少24种的新鲜蘑菇中[1][2]。而且这类物种在世界广泛分布[3]。特别是全球都有种植的双孢蘑菇也含有伞菌氨酸[4]。
不同物种以及蘑菇不同部位间的伞菌氨酸含量也不相同[2]。例如,在生孢蘑菇中,伞菌氨酸的含量(鲜重)介于0.033%与0.173%之间[5],在菌盖和菌褶中最高,在菌柄中最低[6]。伞菌氨酸在蘑菇储存过程中会迅速氧化。在提取过程中,伞菌氨酸水溶液接触到水和甲醇48小时后会完全降解[7]。在蘑菇烹饪过程(可减少90%)和冰冻过程(可减少75%)也会发生降解[8]。
制备与合成
伞菌氨酸可从种植的双孢蘑菇中用水或甲醇提取[1]。
