摘要

研究调查了不同国家（美国、中国、比利时和保加利亚）螺旋藻的一些化学特征。研究包括对螺旋藻中某些元素、生育酚和脂肪酸含量的比较分析。样本中的总脂含量从 1.9%（中国）到 6.1%（比利时）不等。气相色谱法用于测定从不同产地的螺旋藻中分离出来的甘油脂肪酸组成。电感耦合等离子体-光发射光谱法和液相色谱法用于测定元素组成和生育酚含量。保加利亚螺旋藻的脂肪含量接近中国和美国，而比利时螺旋藻的脂肪含量几乎是中国和美国的三倍。研究发现，棕榈酸是所有样本中的主要饱和脂肪酸，保加利亚螺旋藻的这一比例达到 81.2%。不饱和脂肪酸含量最高的是产自美国的螺旋藻。

EVALUATION OF SOME CHEMICAL CHARACTERISTICS OF SPIRULINA FROM DIFFERENT MANUFACTURERS

Some chemical characteristics of Spirulina from different countries (the USA, China, Belgium, and Bulgaria) were investigated. The study includes a comparative analysis of the content of some elements, tocopherols, and fatty acids in spirulina. The total lipids of the examined sample varied from 1.9 % (China) to 6.1 % (Belgium). Gas chromatography was used to determine the fatty acid composition of glyceride oil isolated from spirulina of different origins. Inductively coupled plasma-optical emission spectrometry and liquid chromatography were used to determine the elemental composition and tocopherol content. The fat content of Spirulina from Bulgaria approaches that of China and the USA, while that of Belgium is almost three times higher. It was found that palmitic acid is the main saturated fatty acid in all samples, and for spirulina from Bulgaria, it reaches 81.2 %. The content of unsaturatedfatty acids is highest in that originating in the USA.
