Abstract
A substanially pure chemically bound complex is derived from flax containing secoisolariciresinol diglucoside, cinnamic acid glycosides and hydroxy methyl glutaric acid. The complex is obtained by preparing an aqueous aliphatic alcoholic extract from flax and subjecting this aqueous extract to ultrafiltration whereby low molecular weight species remain with a filtrate and higher molecular weight species comprising the separated complex are retained.
