The plant contains chlorogenic acid and its isomer. Also present are palmitic, stearic, oleic, linoleic acids, along with amino acids, and sugars. Linseed also contains mucilage (3—10%) in epidermis; fatty oil (30—40%); cyanogenic glycosides (0.05—00.1%) mainly linustatin, neolinustatin and linamarin; hgnans; phenyipropane derivatives including linusitamarin. (Cyanogenic glycosides are not found toxic in therapeutic doses as these are broken down only to a limited extent in the body.)
The seeds are an excellent source of dietary alpha-linolenic acid for modifying plasma and tissue lipids. Flaxseed preparations reduced atherogenic risk in hyperhipemic patients. (Cited in Expanded Commission E Monographs.)
Human studies have indicated Flax- seed’s use in atherosclerosis, hypercholesterolemia, lupus nephritis, chronic renal diseases and in cancer prevention (active principle: lignan precursor secoisolariciresinol diglycoside). (Sharon M. Herr. Also Am I Clin Nutr, 1999, 69, 395—402.)
