Fragment-Specific Stable Carbon Isotope Analysis for Screening the Authenticity of Red Yeast Rice Products

Monacolin K (MK) in red yeast rice (RYR) is structurally identical to pharmaceutical lovastatin in its lactone form, making their origins difficult to distinguish. This study examined the δ13C value of hydrolysis-derived 2-methylbutyric acid (2-MBA) as a fragment-specific screeni...
