Amabiline

Amabiline is a pyrrolizidine alkaloid first isolated in 1967 from Cynoglossum amabile.[1] It is also found in the seeds and flowers of borage (Borago officinalis)[2] and in borage seed oil.[3][4]

Chemically, it is the ester derived from viridifloric acid and supinidine.[5]

Amabiline is hepatoxic and may contribute to the potential liver damage caused by consumption of borage and its seed oil.[6]
