From the fermentation culture of an endophytic fungus EN-22 that was derived from the marine red alga Polysiphonia urceolata, fifteen compounds were isolated by column chromatography separation on the normal phase silica gel and Sephadex LH-20, and by the preparative thin layer chromatography (PTLC) as well as by re-crystallization. Structures of all purified compounds were elucidated by analysis of their spectroscopic data including MS, 1D and 2D NMR to be 4-(4-Quinolyl)-4 hydroxy-2-butanone (1), 3-hydroxy-3-(2-oxopropyl)indo-lin-2-on (2), 2-(1H-indol-3-yl)ethanol (3), 1H-indole-3-carboxylic acid (4), 2-hydroxy-3-(1H-indol-3-yl)propanoic acid (5), 2-hydroxy-1-(1H-indol-3-yl)ethanone (6), 3,3-di(1H-indol-3-yl)propane-1,2-diol (7),β-carbolines (8), uracil (9), cyclo-(S-Pro-S-lle) (10), (22E,24R)-3β,5α,9α-trihydroxy-ergosta-7,22-diene-6-one (11), 22E,24R-Sα,6α-epoxyergosta-8,22-dien-3β,7a-diol (12), 5α,6α-epoxy-24(R)-methylcholesta-7,22-dien-3β-ol (13), daucosterol(14), and ergosterol peroxide (15). Compounds 1 and 2 were reported as new natural products.
