Objective: To study the secondary metabolites from endophytic fungus of Astragalus membranaceus. Method: The compounds were isolated by repeated silica gel column chromatography combined with Sephadex LH-20 gel chromatography and identified on the basis of physic-chemical constants and spectral analysis. Result: Eight compounds were obtained and elucidated as 23-methylergosta-7
22-diene-3β
5α
6α-triol (1)
5α
8α-epidioxy-ergosta-6
9(11)
22-trien-3β-ol (2)
cyclotryprostatins A (3)
cyclotryprostatins C (4)
trypacidin (5)
monomethylsulochrin (6)
fumiquinazoline D (7) and fumiquinazoline J (8). Conclusion: The eight compounds were obtained from the endophytic fungus of Astragalus membranaceus for the first time.
