Analysis of an antimicrobial extract prepared from the culture broth of the marine-derived actinomycete Nocardiopsis synnemataformans (HT06 strain) led to the isolation of a new C-glucoside benzoic acid derivative, 4βC-glucopyranosyl-3,5-dihydroxy-2-methoxybenzoic acid (1), along with eight known compounds, norharman (2), (E)-4-(3-hydroxy-4-methoxyphenyl)but-3-en-2-one (3), methyl 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylate (4), 1H-indole-3-ethanol (5), 4-hydroxy-3-methoxybenzaldehyde (6), 3-phenylpropanoic acid (7), phloretic acid (8), and cinnamic acid (9). The antimicrobial activity of all isolated compounds was assayed.
