| 摘 要： | Eight ergostane-type sterols and three their derivatives (one mono-linoleate and two mono-glucosides) were isolated from the ethyl acetate soluble fraction of the fungus Catathelasma imperi.a/e. Two of them are novel compounds, namely 22E,24R-er-gosta-7,22-diene-3β ,5α-diol-6β-linoleate (1) and 22E, 24R-er-gosta-7,22-diene-3β, 5β, 6α-triol (5) with an uncommon c/s-fused A/B ring. Structures of these compounds were demon-strated on the basis of their chemical evidences and spectroscop-ic methods, especially 2D NMR techniques.

| Abstract: | Eight ergostane‐type sterols and three their derivatives (one mono‐linoleate and two mono‐glucosides) were isolated from the ethyl acetate soluble fraction of the fungus Catathelasma imperiale. Two of them are novel compounds, namely 22E, 24R‐ergosta‐7,22‐diene‐3β,5α‐diol‐6β‐inoleate (1) and 22E,24R‐ergosta‐7,22‐diene‐3β,5β,6α‐triol (5) with an uncommon cis‐fused A/B ring. Structures of these compounds were demonstrated on the basis of their chemical evidences and spectroscopic methods, especially 2D NMR techniques. |
