Sinigrin (Allylglucosinolate) Analysis Service
Online InquiryWhat is Sinigrin?
In the realm of plant chemistry, one compound that has been the focus of research is sinigrin, or allylglucosinolate, a type of glucosinolate compound found in various plants, particularly within the Brassica vegetable family. This secondary metabolite is generated as a means of defense against herbivores and other predators.
Structure of sinigrin
Sinigrin's potential health advantages have piqued the interest of researchers, as it exhibits anti-inflammatory, anti-cancer, and anti-oxidative properties. These therapeutic properties are believed to stem from the degradation of sinigrin into its biologically active derivatives, specifically allyl isothiocyanate and 1-cyano-2,3-epithiopropane.
Recent years have seen a rise in the importance of sinigrin analysis within different plant tissues and food products due to its potential health benefits. Such an analysis can offer valuable insight into the composition and qualities of this compound, as well as its potential applications in the food and pharmaceutical sectors.
Sinigrin sources and its therapeutic activity (picture from Mazumder, Anisha, et al., 2016)
One of the most widely used methods for the analysis of sinigrin and its derivatives is liquid chromatography-mass spectrometry (LC-MS).
For LC-MS analysis of sinigrin, the sample is first extracted using a suitable solvent and then purified using solid phase extraction (SPE) or other techniques. The purified sample is injected into a liquid chromatography system where sinigrin and its derivatives are separated based on their chemical properties. The separated compounds are then detected and quantified using highly sensitive and selective mass spectrometry. LC-MS analysis of sinigrin can be performed using a variety of mass spectrometry techniques, including electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI). These techniques can provide accurate and precise quantification of sinigrin and its derivatives, even at low levels.
