一株嗜碱放线菌发酵液中的抗肿瘤活性成分

摘要

Four antitumor components were isolated from the culture broth of the alkalophilic actinomycete YIM 80149.They were identified as 4',7-dihydroxyisoflavone (1),4' ,5,7-trihydroxyflavone(2),3-(4-hydroxy-3 -methoxyphenyl)-2(E)-propenoic acid(3),2-methoxy-1,4-naphthoquinone(4)on the basis of the spectroscopic analysis.%从嗜碱放线菌YIM 80149的发酵液中分离得到4个抗肿瘤活性成分.根据波谱数据,鉴定为4',7-dihydroxyisoflavone(1)、4',5,7-trihydroxyflavone(2)、3-(4-hydroxy-3-methoxyphenyl)-2(E)-propenoic acid(3)、2-methoxy-1,4-naphthoquinone(4).
