Monascin

Monascin is a yellow azaphilone pigment produced by Monascus species, the mould used to prepare red yeast rice. Its formula is C21H26O5 and its molecular weight is 358.43, and it is supplied as a solid. Food-analysis and natural-product laboratories use it as a reference standard when characterising Monascus fermentation products, in which a family of related pigments must be separated and identified. It supports method development for HPLC or LC-MS determination of pigment content in red yeast rice preparations and dietary ingredients, and it allows retention times and response factors to be checked against an authenticated standard. Storage is specified at -20 C +/- 5 C, with ice packs used for shipment. Pack sizes of 1 mg, 5 mg, 10 mg, 20 mg and 50 mg are listed. Enquiries about a quotation or the supporting analytical file can be made through the form on this page.
