Figure 1

Extracted ion chromatogram of sporangia extracts showing putative EPA-containing lipids. EIC of sporangia extracts for m/z 285.2212 (±2 ppm), a characteristic ion of EPA, is presented. Peaks corresponding to EPA-containing ions (Table 1) are numbered from 1 to 5 and retention times are indicated. Peak 1: M377T39 = EPG; peak 2: M303T44 = EPA; peak 3: M661T85 = DEPG; peak 4: M642T142 = diglyceride 20:5/18:1; peak 5: M946T474 = TEPG. Identity of EPA, EPG, DEPG, and TEPG have been confirmed by using the corresponding standards.
