Secoisolariciresinol diglucoside
- Secoisolariciresinol diglucoside
Secoisolariciresinol diglycoside (SDG) (C32H46O16) is an anti-oxidant phytochemical present in flax, sunflower, sesame, and pumpkin seeds. It is a precursor of mammal lignans and a phytoestrogen.
Animal studies have shown SDG can prevent the development of atherosclerosis and diabetes, and has beneficial modifying effect on blood and cholesterol levels.
Secoisolariciresinol diglucoside can be isolated from de-fatted (hexane extraction) flaxseed by extraction of the lignan polymer precursor with a water/acetone mixture, followed by acetone removal and alkaline hydrolysis.
