海洋真菌Nigrospora sphaerica的化学成分(Ⅱ)
Journal of Shenyang Pharmaceutical University(2010)
Abstract
目的对海洋真菌Nigrospora sphaerica中的化学成分进行研究。方法采用硅胶柱色谱、凝胶以及HPLC等方法进行分离纯化,根据理化性质和光谱数据进行结构鉴定。结果分离得到了8个化合物,分别鉴定为柄曲霉素(sterigmatocystin,1)、4-苄基-3-苯基-5氢呋喃酮(4-benzyl-3-phenyl-5H-furan-2-one,2)、异黄光素[7,8-dimethyl,benzo(g)pteridine-2,4(1H,3H)-dione,3]、5,8二羟基-7甲氧基黄酮(5,8-dihydroxy-7-methoxy-2-phenyl,4H-1-benzopyran-4-one,4)、1(2H)-3,4-二氢-4,8二羟基萘[3,4-dihydro-4,8-dihydroxy,1(2H)-naphthalenone,5]、3,5双去氧-5-苯基戊糖酸γ内酯(3,5-dideoxy-5-phenyl-,γ-lactone,pentonic acid,6)、4-羟基苯乙醇乙酯(4-hydroxyphe-nylethyl acetate,7)、1,4-二氧-2,5-二酮-3,6-二苯甲基聚酯[3,6-bis(phenylmethyl)-1,4-dioxane-2,5-dione,8]。结论真菌Nigrospora sphaerica为首次从海洋中分离得到,化合物1-8为首次从该菌中分离得到。
