the fungus, C. rosea B5-2, and induced the production of four new compounds, (-)-dihydrovertinolide (2), and clonostach acids A (3), B (4), and C (5) together with the known compound, (-)-vertinolide (1). The new compound (-)-dihydrovertinolide (2) exhibited phytotoxicity against lettuce seedlings at a concentration of 50 mg L−1.
抽象的 从红树林植物中分离出内生真菌Clonostachysrosea B5-2,并对其进行一株多化合物 (OSMAC) 方法。通过这种方法,发现培养基的修饰增强了C.rosea B5-2 次生代谢产物的产生。添加苹果汁的固体大米培养基导致真菌C. Rosea B5-2 的次生代谢发生显着变化,并诱导产生四种新化合物:(-)-二氢维叶内酯 ( 2 ) 和克隆穗酸 A ( 3) )、B( 4 )和C( 5 )以及已知化合物(-)-维替内酯( 1 )。新化合物(-)-二氢维叶内酯( 2 )在浓度为50 mg L -1时对生菜幼苗表现出植物毒性。
