Abstract

<jats:p>Two pyrido[2,3-<jats:italic>b</jats:italic>]pyrazines were isolated from the extract of the springtail <jats:italic>Tetrodontophora bielanensis</jats:italic> (WAGA). Their structure were determined by mass and NMR spectroscopy: 2,3-dimethoxypyrido[2,3-<jats:italic>b</jats:italic>]pyrazine (<jats:italic>I</jats:italic>) and 2-methoxy-3-isopropylpyrido[2,3-<jats:italic>b</jats:italic>]pyrazine (<jats:italic>II</jats:italic>).
