Summary, etc. <p style="text-align: justify;">Bioassay-guided fractionation and chromatographic purification of the crude extract of ruminal bacterium <em>Enterobacter amnigenus</em> ZIH (isolated from cattle) produce one new microbial product:butyl-a-D-glucopyranoside together with eleven known compounds including (<em>S</em>)-brevinic acid, 3-(hydroxyacetyl)-indole, <em>N<sub>ß</sub></em>-acetyltryptamine, tyrosol, phenol, tryptophol, indole-3-lactic acid, uracil, adenine and two diketopiperazines <em>cyclo</em>-(Phe, Pro) and <em>cyclo</em>-(Leu, Pro). The complete NMR assignments of butyl-a-D-glucopyranoside was done - using different spectroscopic (<sup>1</sup>H, <sup>13</sup>C, <sup>1</sup>H-<sup>1</sup>H COSY, HMQC, and HMBC) and spectrometric methods (ESI-MS, HRESI-MS). Compounds 1a and 2 reported for the first time from a natural source. The bacterial extract exhibited high cytotoxicity against brine shrimp and moderate antimicrobial activity against a diverse set of pathogenic bacteria strains.</p>
