Objective: To study the secondary metabolites of endophytic fungal strain Botryosphaeria sp. MHF of Maytenus hookeri. Method: The chemical constituents were isolated by column chromatography such as normal phase or reverse phase etc. The structures were identified by spectroscopic analysis. Result: Eight compounds were obtained and elucidated as 22E
24R-ergosta-5-en-3β-ol ( 1 )
22E
24R-ergosta-4
6
8
22-tetraen-3-one ( 2 )
22E
24R-3β
5α
9α-trihydroxy-ergosta-7
22-diene-6-one ( 3 )
22E
24R-ergosta-7
22-diene-3β
5α
6β-triol ( 4 )
22E
24R-5α
8α-epidioxyergosta-6
22-dien-3β-ol ( 5 )
fusaproliferin ( 6 )
cerebroside C ( 7 ) and 3
4
5-trihydroxy1-tetralone ( 8 ). Conclusion: All these compounds were isolated from this strain cultivated on Murashige-Skoog culture medium for the first time.
