Mucilage mustard

A pectic polysaccharide containing D-galacturonic acid and terminal units of 4-O-methyl-D-glucuronic acid, along with L-rhamnose and D-galacto-pyranose, was purified from yellow mustard mucilage.124 Pectins are prevalent... 

W. Cui, M. N. A. Eskin, C. G. Biliaderis, and K. Marat, NMR characterization of an 4-0-methyl-/l-D-glucuronic-acid containing rhamnogalacturonan from yellow mustard (Sinapis alba L.) mucilage, Carbohydr. Res., 292 (1996) 173-183. 

Main components 1-2% sinigrin, which is split enzymatically into allyl isothiocyanate (water-vapour volatile and main constituent of mustard oil), glucose and potassium hydrogensulphate, as well as the bitter-tasting sinapin, phytin, protein, 30-35% vegetable oil and mucilage (less than in white mustard). 

Mucilages Wide range of branched and substituted galactans Flax seed, psyllium, mustard seed... 

White, or yellow, mustard (5. alba) contains the glucosinolate sinalbin, which on hydrolysis by enzymes present (myrosin or glucosinolases) yields /i-hydroxybenzyl isothiocyanate (a relatively nonvolatile compound), -hydroxybenzylamine, and other similar components (proteins, fixed oils, sinapine, rhamnogalacturonan mucilage, etc.) as brown mustard (jiangsu marsh).
