Six new compounds were isolated from the methanol extract of Arachinoides standishii OHWI.Chemical and physicochemical studies showed their structures to be 1-(2,4,6-trimethoxyphenyl)-but-trans-2-en-1-one (I), 5,7-dimethoxy-2-methylchromanone (II), 2-ethyl-5,7-dimethoxychromanone (III), 5-hydroxy-dimethoxy-2-methyl-chromanone (IV), 3-β-D-allosyloxy-1-(2-hydroxy-4,6-dimethoxyphenyl)-butan-1-one (V) and 8-carboxy-6-hydroxy-2,5-dimethyl-2a,3,4,5-tetrahydroacenaphthene (VI).Compound VI, named ryomenin, is the first sesquiterpene reported to possess a tetrahydroacenaphthene skeleton.Keywords - Arachinoides standishii; Aspidiaceae; 1-phenylbutan-1-one derivatives; 1-phenylbut-trans-2-en-1-one derivatives; D-alloside; chromanones; tetrahydroacenaphthene derivatives; sesquiterpene; X-ray analysis
