Parts used
Laggera decurrens contains specific phytotoxic compounds that are concentrated within its leaf structures. Research into these leaves has led to the isolation of two physiologically active substances, namely 3-hydroxythymoquinone and 5-acetoxy-2-hydroxythymol. When applied to biological models, these leaf-derived compounds induce rapid chlorosis and necrosis in species like Lemna minor. Furthermore, the chemical properties found in the foliage demonstrate a significant ability to inhibit the growth and germination of various weeds. While the exact mode of action remains unknown, these leaves clearly play a vital role in the plant's chemical defense mechanisms.
