摘要

Litchficin (1), a new acyloin, and three known metabolites, N-succinylanthranilic acid (2), kurasoin A (3), and soraphinol B (4), were isolated from a coral-derived halophilic Gram-positive bacterium, Litchfieldia sp. TUR-22. Compounds 14 at 10 µg ml−1 suppressed the radicle elongation of lettuce seeds to 38–56% of nontreated seeds.
