A new phomapyrone derivative (1), and 9 known compounds were isolated from the ethyl acetate fraction of solid fermentation of Fusarium redolens, the endophytic fungus from Edgeworthia chrysantha, by using various isolation techniques such as Sephadex LH-20, MCI GEL and Semi pre-HPLC, etc. Their structures were identified by spectroscopic analysis, including MS, UV, CD, specific rotation, IR, 1D and 2D NMR, as (+)-7S-4-deoxy-9-hydroxyphomapyrone C (1), uracil (2), uridine (3), 2'-deoxyuridine (4), adenosine (5), 2'-deoxyadenosine (6), cordysinin B (7), ergosterol (8), ergosta-5α, 8β-epidioxy-6, 22-dien-3β-ol (9), and (22E, 24S)-3α-hydroxy-24-methylcholesta-5, 8, 22-trien-7-one (10).
