Two new rhabduscin analogues were isolated and purified from fermentation broth of Xenorhabdus bovienii SN52 by silica gel column chromatography, sephadex LH-20 chromatography and high performance preparative liquid chromatography. On the basis of spectroscopic methods (HR-ESIMS, 1D- and 2D-NMR) and by comparison with those reported previously, their structures were identified as 4-O-(4-acetamide-β-L-rhamnoside)-benzaldehyde (1) and 4-O-(4-acetamide-β-L- rhamnoside)-(Z)-N-styrylforma mide (2). Their inhibitory activities against phenoloxidase were also tested.

Key words: Xenorhabdus bovienii, rhabduscin analogues, structural identification, phenoloxidase inhibitory activity
