EqtI and III were isolated from the sea anemone A. equina as described (MacÏek
and Lebez, 1988) and were separately subjected to RP±HPLC. EqtIII eluted as a
single peak with a retention time of 26 min. In contrast, EqtI eluted in two peaks,
EqtI ' and EqtI0, with similar retention times of approximately 27 min (Fig. 4).
