title: Secondary metabolites from the red mould rice of Monascus purpureus BCRC 38113.
abstract: One new tetralone, monaspurpurone (1), was isolated from the EtOH extract of a yellow mutant of the fungus Monascus purpureus BCRC 38113 (Eurotiaceae) grown on rice, along with five known compounds, β-sitosteryl palmitate (2), ergosterol (3), ankaflavin (4), monascin (5) and p-nitrophenol (6). They were characterised on the basis of spectral analysis and comparison with literature data. All the isolates were also evaluated for the scavenging properties towards the DPPH in TLC autographic and spectroscopic assays.
