A new menthane-type monoterpenoid, illigerate E (), as well as two known ones, (1,3,4,6)-6,8-dihydroxymenthol () and -4-hydroxy-5-(1-hydroxy-1-methylethyl)-2-methyl-2-cyclohexene-1-one (), were isolated from fermented with 828H2. Their structures were identified by HRESIMS and 1D/2D NMR spectra. Their inhibitory effects of NO production in RAW 264.7 macrophages were estimated.
