Determination of indolic compounds from underivatized samples from T. virens growth medium by GC-MS. A, Total ion chromatogram of IAAld and IEt from neutral ethyl acetate extract obtained from 1 L of culture medium of T. virens. B to E, The 70-eV electron-impact full-scan mass spectra from m/z 50 to 500 of IAAld identified in the extract (B), the standard IAAld (C), IEt identified in the extract (D), and the standard IEt (E). Determinations were done from at least five independent samples.
