One unusual aromatic monacolin analog, aromonacolin A (1), was isolated from the ethanolic extract of Monascus purpureus ‐fermented rice. Its structure was elucidated by extensive spectroscopic (HRESIMS, 1 H NMR, 13 C NMR, HSQC, HMBC, and NOESY) and chemical methods. The absolute configuration of the C‐6 secondary alcohol was deduced via the circular dichroism data of the in situ formed [Rh 2 (OCOCF 3 ) 4 ] complex.
