Figure 3: LC–MS/MS screenings for dalesconols A–C (1–3) from tricyclazole-exposed fungal cultures.

The samples were prepared from the EtOAc extracts of D. eschscholzii cultures without (1) and with exposures to tricyclazole at 30 (2), 50 (3), 100 (4) and 150 mg l−1 (5). The LC–MS/MS profiles in an EIC mode (a–c) were acquired in MRM (multiple reaction monitoring) mode where the authentic dalesconols A–C signified in the ESI (electrospray ionization interface) /MS/MS product ion spectrum (d–f).
