结果：在本色谱条件下腺苷蛋氨酸与辅料、溶剂峰及其有关物质的分离度符合要求，在200～600μg·mL~(-1)范围内线性良好(r=0.9998)。回收率为99.61%～99.98%，RSD为0.23%～1.3%。

S-adenosylmethionine is a naturally occurring molecule, which widely distributes throughout tissues and fluids. It has been one of the very important pharmaceuticals because of its essential role in transmethylation, transsulphuration and transaminopropylation.

S-腺苷蛋氨酸是一种广泛存在于各种组织和细胞中的生物小分子，具有转甲基、转硫和转氨丙基等重要生理作用，已成为治疗肝损伤、胆汁郁积和抑郁症等疾病的重要药物。

RESULTS: Intracerebroventricular injection of SAM produced a significant decrease in blood pressure and heart rate of the anesthetized rats.

结果：侧脑室注射S-腺苷蛋氨酸能够显著降低麻醉大鼠的血压，减慢大鼠的心率。

The optimum condition for separating and purifying SAM was using the solution at pH of 5.0 containing 3.0 g SAM per liter at the flow velocity of 6 L/h through the ion-exchange column (φ50 mm×1500 mm)filled with D152 resin. Impurities were removed first by eluting the column with double-distilled water and acetic acid, and then with 9 L to 15 L of sulfuric acid of 50 mmol/L concentration at the flow velocity of 6 L/h.

论文对SAM的性质、药理作用以及当前国际上关于SAM的研究进展进行了较为详尽的综述，并在此基础上确立了研究内容，取得了如下成果： 1利用本实验室构建的基因工程菌JM71发酵生产S-腺苷-L-蛋氨酸，在50 L发酵罐中发酵6天后，SAM终产量达到6 g/L发酵液。
