Abstract：Five samples of spirulina from different producing areas were analyzed and characterized with X-ray fluorescence analysis. The contents of K, Na, Ca, Mg, Fe, Zn and Mn in spinrulina samples from different producing areas were determined. The results show that spinrulinas are rich in microelements that human body needs. The spectra of main elements of spirulina from different producing areas are similar, but the content of each elements is different. The content of K is 5.00% averagely, the highest in the five samples, the content of Na is 0.352%, and the ratio of Na/K is 0.070 on average. The relationship between K, Na/K and medical care efficiency was studied. Lesser value of Na/K is helpful to hypertension patients. It was suggested that hypertension patients should take in less Na, but more K. This can help prevent and cure hypertension. The method proves to be simple, rapid, accurate, and highly sensitive, and can be used for simultaneous multielement determination. The authors’ study provides a new scientific foundation for further study and general application of spirulina.
