Na^+-K^+/ATP酶抑制剂的研究 Ⅲ.SIPI-90-653菌株中小组份的研究

Studies on minor components of SIPI90653 strain

从ＳＩＰＩ－９０－６５３菌株中分离得到２个小组份，经ＵＶ、ＥＩ、ＦＡＢ、１Ｈ－ＮＭＲ、１３Ｃ－ＮＭＲ、１Ｈ－１ＨＣＯＳＹ、１３Ｃ－１ＨＣＯＳＹ及化学分析证实其结构分别为芦他霉素和ｖｕｌｇａｍｙｃｉｎ。两个化合物有较强的抗虫活性。

Two minor components were isolated from SIPI90653 strain. Their structures were deduced as rutamycin and vulgamycin respectively by means of IR, UV, 1HNMR, 13CNMR, 1 H1H COSY, 13C1H COSY methods and chemical analysis. These two compounds have moderate insecticidal activity.
