Fig. 2. HPLC profile of the ethyl acetate extract. The profile was recorded with ESIMS in positive ion mode (A), ELSD (B), and PDA (C). Peak numbering designates compounds 1–14. The peak labelled with * has been tentatively assigned to the epoxy precursor of 6 (m/z 468 [M H]+ /466 [M-H]; 216, 294, and 319 nm). BPC: + λmax base peak chromatogram.
