Objective: To study the secondary metabolites from endophytic fungus AR08 of Astragalus membranaceus. Method: The compounds were isolated and purified by silica gel column chromatography
Sephadex LH-20
and HPLC. Their structures were identified by the spectral analysis. Result: Six fumiquinazoline alkaloids were obtained and elucidated as fumiquinazoline J (1)
fumiquinazoline I (2)
fumiquinazoline C (3)
fumiquinazoline H (4)
fumiquinazoline D (5)
and fumiquinazoline B (6). Conclusion: Compounds 2 and 4 were obtained from the plant endophytic fungus for the first time.
