| Abstract: | Endophytes, commonly present in higher plants, are important sources of natural products with pharmaceutical potential. A new sesquiterpenoid, 4-deacetyl-10-oxo-dihydro-botrydial(1), and a new sterol, 22E,24R-5α,8α-epidioxyergosta-6,22-dien-3β-formate(2), were isolated from solid cultures of an endophytic fungal strain Phomopsis species Lz42, cultivated on Maytenus hookeri, together with five related known compounds, 4β-acetoxy-9β-10β-15α-trihydroxyprobotrydial(3), 22E,24R-5α,8α-epidioxyergosta-6,22-dien-3β-ol(4), ergosterol(5), 22E,24R-ergosta-7,22-diene-3β,5α,6β-triol(6) and 22E,24R-ergosta-7,22-diene-3β,5α,6β,9α-tetraol(7). Their structures were identified by extensive spectroscopic, experiments especially 2D-NMR. |
