Publication date: Available online 21 November 2017 Source:Mycoscience Author(s): Arif Yanuar Ridwan, Jing Wu, Jae-Hoon Choi, Hirofumi Hirai, Hirokazu Kawagishi Six compounds, 5-(1-hydroxyethyl)dihydrofuran-2(3H)-one (1), 4-ethoxy-4-oxobutanoic acid (2), 4-ketononanoic acid (3), methyl(2-acetylaminoethyl)sulfoxide (4), methyl benzoate (5) and p-hydroxybenzoic acid (6) were isolated from the fruiting bodies of Cortinarius caperatus. Compounds 1, 3, 5, and 6 inhibited growth of Flammulina velutipes mycelia. Compounds 2, 3, 5, and 6 exhibited growth regulatory activities toward rice seedlings, while compounds 3, 5, and 6 regulated the growth of lettuce. Compound 4 was first isolated from a natural source. In addition, the activity of compound 6 against rice was compared with those of its analogs.
