Reinvestigation of the toxins from the blue‐green alga,Aphanizomenon flos‐aquae, by a high performance chromatographic method

Abstract

Toxic red tides due to blue green alga‐Aphanizomenon flos‐aquae are becomming common occurrence in the lakes of New Hampshire. The toxins from Aphaizomenon flos‐aquae were purified by a high performance chromatographic method. One of the toxins was identified as saxitoxin; the other three gave reactions indicating their structural similarity to toxins isolated from Gonyaulax tamarensis.
