|Section2= }} Secoisolariciresinol diglucoside (SDG) is an antioxidant phytoestrogen present in flax, sunflower, sesame, and pumpkin seeds. In food, it can be found in commercial breads containing flaxseed.〔Phenolic glucosides in bread containing flaxseed. C. Strandås, A. Kamal-Eldin, R. Andersson and P. Åman, Food Chemistry, Volume 110, Issue 4, 15 October 2008, Pages 997–999, 〕 It is a precursor of mammal lignans which are produced in the colon from chemicals in foods. == Extraction == 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.〔 ''Process for recovering secoisolariciresinol diglycoside from de-fatted flaxseed''.〕 Or, it can be extracted from the shell of whole flax through a cold-milled process without using chemicals. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「secoisolariciresinol diglucoside」の詳細全文を読む スポンサード リンク
