<jats:title>Abstract</jats:title><jats:p>Five minor prodiginine pigments were isolated from <jats:italic>Actinomadura madurae</jats:italic> and <jats:italic>A. pelletieri</jats:italic> fermentations. Two of the pigments were shown to be methylcyclooctylprodiginine (<jats:bold>7</jats:bold>) and ethylcyclononylprodiginine (<jats:bold>8</jats:bold>). For the others, structures containing oxygen functions in the aliphatic chains (<jats:bold>11</jats:bold>, <jats:bold>12</jats:bold> and <jats:bold>13</jats:bold>) were suggested.
