When the enzyme in the plant breaks down, the compound sinigrin
is transformed into mustard oil that has many health benefits.
Mustard also contains a glucosinolate called sinigrin
. The combination of myronsinase and sinigrin
produces AITC, which is responsible for the characteristic pungency of mustard oil.
In addition some studies have identified effective compounds within Erysimum plants such as methylthioalkyl, methylsulfinylalkyl and methylsulfonylalkyl glucosinolates , sinigrin
, progoitrin, glucoiberin, 3-(methylcarbonyl)propyl glucosinolate, glucocheirolin and glucoerysolin , 4-isothiocyanatobutanoic acid , cardiac glycoside .
Glucosinolates (progoitrin, sinigrin
, and gluconapin) were confirmed by a Finnigan LCQ Deca XP plus Ion Trap Mass Spectrometer system (Thermo Finnigan, San Jose, CA, USA) which confirmed by LC-ESI-MS in positive mode.
xylostella has been investigated based on two major characteristics: the presence of alkanes in the foliar wax, and sinigrin
content in leaves (Lin et al.
pekinensis, (ii) the GL standard of sinigrin
(Sigma-Aldrich, Taufkirchen, Germany), and (iii) Gl standard of glucotropaeolin (benzyl GL) (ceded by Professor of Eduardo Rosa from University of Tras-os-Montes e Alto Douro, Vila Real, Portugal and Dr.
Glucoiberin, progoitrin, glucoraphanin, sinigrin
, gluconapin, and glucoerucin were detected as aliphatic glucosinolates as well as an aromatic glucosinolate gluconasturtiin.
The characteristic hot flavour is mainly the result of the enzyme-mediated breakdown product called allyl isothiocyanate (allyl ITC) which is formed from the prodrug sinigrin

) in the regulation of water transport in Brassica oleracea grown under salt stress," Physiologia Plantarum, vol.
For example, Syringinenin (MOL000347, DL=0.32, 0B=14.6%), Sinigrin
(MOL013312, DL=0.18, OB=3.9%), Goitrin (MOL001811, DL=0.01, OB=3.2%), Sinigrin_qt (MOL001761, DL=0.03, OB=21.2%) being the major bioactive ingredients of Radix Isatidis.
Spodoptera litura was reared on 2 diets, i.e., on castor leaves (Ricinus communis L.; Malpighiales: Euphorbiaceae) which is the natural food, and a synthetic meridic diet containing chickpea seeds and sinigrin
as a phagostimulant.
Developmental changes of sinigrin
and glucoraphanin in three Brassica species (Brassica nigra, Brassica juncea and Brassica oleracea var.
