Structure elucidation and complete NMR spectral assignment of an unusual aromatic monacolin analog from Monascus purpureus-fermented rice

One unusual aromatic monacolin analog, monacophenyl, was isolated from the ethanolic extract of Monascus purpureus‐fermented rice. Its structure was completely and unambiguously assigned by one‐ and two‐dimensional NMR techniques (1H NMR, 13C NMR, HSQC, HMBC and NOESY) and high‐resolution ESI‐MS spe...
