L-含羞草素 [β-N（3-羟基-4-吡啶酮）-α-氨基丙酸] 是一种非蛋白质氨基酸，是热带豆科植物，如 银合欢 和其他属于 含羞草 属豆科植物的重要成分。除 3,4-二羟基苯环被 3-羟基-4-吡啶酮环取代外，结构上 L-含羞草素与二羟基苯丙氨酸相似。 Koa hoale 种子中的 L-含羞草素已被用于研究其在慢性炎症反应（高锰酸钾诱导的慢性肉芽肿）中的抗炎作用。 L-mimosine [β-N (3-hydroxy-4-pyridone)-α-amino propionic acid] is a non-protein amino acid and is a vital component of tropical legumes, such as Leucaena glauca and other legumes belonging to Mimosa spp. Structurally L-mimosine resembles dihydroxyphenylalanine except 3,4-dihydroxy-phenyl ring replaced by 3-hydroxy-4-pyridone ring. L-Mimosine from Koa hoale seeds has been used to study its anti-inflammatory effect in chronic inflammatory response (potassium permanganate - induced chronic granuloma).
