Abstract	The diarrhetic shellfish poisoning (DSP) toxin okadaic acid (1) is found in extracts of the dinoflagellate Prorocentrum lima together with a suite of diol esters such as 2. When 2 was added to the culture medium of the centric diatom Thalassiosira weissflogii, it was transformed into a range of products within three days. Three of these products, 3, 4 and 5, were isolated from the medium and identified as oxidation products 2, suggesting that the diatom produces DSP metabolites of greater polarity as a means of detoxification. In addition, another diol ester product 6 was identified as a minor impurity of 2.
