A new surfactin isomer (1) was isolated from a mangrove bacteria strain ‘ Bacillus sp’. Its structure was identified, and full assignments of 1 H and 13 C NMR spectral data were achieved for the first time by a combination of mass spectrometry and 1D and 2D NMR experiments including DEPT, 1 H 1 H COSY, HSQC, HMBC, TOCSY, ROESY, and HSQC‐TOCSY. The NMR spectral data of eight known analogs (2–9) are also reported. Copyright © 2007 John Wiley & Sons, Ltd.
