Amabiline
Amabiline is a pyrrolizidine alkaloid first isolated in 1967 from Cynoglossum amabile. It is also found in the seeds and flowers of borage and in borage [seed oil].
Chemically, it is the ester derived from viridifloric acid and supinidine.
Amabiline is hepatotoxic and may contribute to the potential liver damage caused by consumption of borage and its seed oil.
