| Abstract: | The polyamine profiles of the toxic dinoflagellate Alexandriumminutum during different growth stages were measured by high-performanceliquid chromatography. Both free and conjugated polyamines werefound, including putrescine, cadaverine, spermine, spermidineand norspermidine. During the growth cycle of A. minutum T1,the levels of norspermidine and putrescine in the free polyamineswere the highest after 3 days culture. Putrescine and cadaverinewere the major components in the conjugated polyamines. Theamount of conjugated amines was higher than that of free aminesduring the exponential phase of A. minutum T1. |
