不等弯孢菌HS-FG-257中一个新的苯甲酸类化合物

摘要

从土壤不等弯孢菌HS-FG-257中分离得到4个化合物,通过波谱学鉴定为4-hydroxy-3-(3-methyoxy-3-methylbutyl) -benzoic acid(1),4-hydroxy-3-(3-hydroxy-3-methylbutyl) -benzoic acid(2),4-hydroxy-3-prenylbenzoic acid (3) and radicinin (4),其中化合物1为新化合物.%A new benzoic acid derivative,4-hydroxy-3-( 3-methyoxy-3-methylbutyl ) -benzoic acid ( 1 ),along with two known benzoic acid variants,4-hydroxy-3-(3-hydroxy-3-methylbutyl) -benzoic acid (2),4-hydroxy-3-prenylbenzoic acid (3) and a known metabolite,radicinin (4),were isolated from Curvularia inaequalis strain.HS-FG-257.The new compound was structurally elucidated by spectroscopic methods
