Heterocapsa triquetra (Ht), a non-toxic dinophyte, was selected to investigate the presence of pigments inhibiting melanoma cells growth. We developed an innovative microwave-assisted extraction process (MAE), determined the Ht pigment composition using Reverse Phase-High Performance Liquid Chromatography (HPLC) and high-resolution Ultra Performance Liquid Chromatography-Mass Spectrometry E (UPLC-MSE) analysis and assessed their antiproliferative activity in human invasive melanoma cells (A2058) grown in vitro. MAE allowed a fast and efficient extraction of Ht pigments as compared with conventional processes (soaking, sonication). Seventeen pigments and derivatives were unequivocally identified by UPLC-MSᴱ in the Ht extract, among which two were supposed...
