中文摘要：

旨在探明几种常见海洋经济水产品的牛磺酸含量,特别是杂色蛤（Ruditapes philippinarum）中牛磺酸含量随季节变化的规律.以杂色蛤为原料,制备牛磺酸并利用高压液相色谱法分析牛磺酸的纯度.结果发现,几种常见海洋经济水产品中,杂色蛤体内的牛磺酸含量最高,达8.22 g/kg.以此为原料可制备纯度达92.92%的天然牛磺酸.杂色蛤中牛磺酸含量的季节变化规律为：1—4月牛磺酸含量逐渐升高,4—8月逐渐下降,至8月份达最低点,9月后又逐渐回升,牛磺酸含量介于1784.57-2519.74μg/m L之间.而且,牛磺酸含量的季节变化规律与气温变化基本呈反相关关系.

英文摘要：

This study aims to analyze the contents of taurine in different species of pecially seasonal variation of taurine content in Ruditapes philippinarum. Using material, taurine was prepared and its purity was determined by high performance The results showed that the taurine content varies with species and the highest content marine products, es- philippinarum as raw liquid chromatography was in pinarum which was 8.22 g/kg. The purity of taurine extracted from Ruditapes philippinarum was 92.92%. Concerning seasonal variation of taurine content in Ruditapes philippinarum, it increased from January to A- pill, then decreased from April to August, while from August to December, an increment was then ob- served. The taurine content was in the range of 1784. 57 - 2519.74μg/mL. Aninverse correlation between seasonal variation of taurine content and the change of air temperature was noticed.
