Liquid chromatography-tandem mass spectrometry (LC-MS/MS) identification of candicidin in S4 extracts. Analysis of S4-derived extracts. Left panel (A), ultraviolet spectrum extracted at RT 8.3 min (see panel B) from the S4 extract. The absorption maxima match those previously reported for candicidin D . Right panel (B), LC-MS analysis of S4 extract. Ion chromatograms extracted for the molecular ion of candicidin D (m/z 1109.6) are shown. (C), MS2 analysis of the extracted ion m/z 1109.6. The fragmentation pattern of the antifungal compound from Streptomyces S4 perfectly matched the fragmentation of candicidin as reported previously . The ions highlighted in the Haeder et al. study  are labelled in a larger font.
