Abstract:

从采自大连近海的红藻鸭毛藻(Symphyocladialatiuscula)中分离到一株肉座菌目真菌(Hypocrealessp.),对其发酵代谢产物的化学成分进行了研究。利用正相硅胶柱层析、葡聚糖凝胶SephadexLH-20柱层析、制备薄层层析(PTLC)以及重结晶等分离手段,并通过一维、二维核磁共振技术、质谱技术等从该菌发酵液中分离鉴定了10个化合物:双酚A(1);邻羟基苯甲酸(2);吲哚甲酸(3);吲哚乙酸(4);N-乙酰色胺(5);(22E,24R)-麦角甾-7,9,22-三烯-3β-醇(6);过氧化麦角甾醇(7);(22E,24R)-5α,6α-环氧麦角甾-8,22-二烯-3β,7α-二醇(8);(22E,24R)-麦角甾-7,22-二烯-6β-甲氧基-3β,5α-二醇(9);啤酒甾醇(10)。这些化合物均为首次从该菌中分离得到,其中化合物1为首次作为天然产物分离得到。
