Occurrence

Gramine has been found in the giant reed, Arundo donax,^[2][3] Acer saccharinum (Silver Maple),^[4] Hordeum,^[1][3] (a grass genus that includes barley) and Phalaris^[3] (another grass genus).

Effects and toxicity

Gramine has been found to act as an agonist of the adiponectin receptor 1 (AdipoR1).^[5]

The LD50 of gramine is 44.6 mg/ kg iv in mice and 62.9 mg/ kg iv in rats.^[6] Numerous studies have been done on the toxicity of gramine to insects harmful to crops in order to assess its potential use as an insecticide.^[7]
