摘要:
从苦竹内生真菌Fusarium sp.S13的发酵液提取物中分离得到8个化合物,通过波谱技术分别鉴定为:cerevisterol (1),(22E,24S)-24-methyl-5 α-cholesta-7,22-diene-3β,5α,6β,9α-tetraol (2),ergosterol peroxide (3),3β,5α,9α-trihydroxy-6β-methoxyergosta-7,22-dien (4),ergosta-7,22-dien-6β-methoxy-3β,5 α-diol(5),ergosta-4,6,8 (14),22-tetraen-3-one(6),25-hydroxy-ergosta-4,6,8(14),22-tetraen-3-one (7),ergosta-7,22-dien-3β,6β-diol (8).海虾致死实验结果显示化合物1-8均显示出不同程度的毒性.
