研究表明，在所检测的啤酒中，亚精胺、精胺和腐胺占啤酒中生物胺的大多数，其含量分别为51%，19%和11%。

The contents of putrescine and spermidine increased more obviously in high responding line and decreased significantly in low responding lines.

敏感型材料的游离脯氨酸、丝氨酸、精氨酸、丙氨酸含量水平明显比迟钝型材料的高。25d低温预处理后，敏感型材料的多胺总量比0d时的明显提高，腐胺和亚精胺的含量升幅特别显著；迟钝型材料的多胺总量比0d时的低，亚精胺和精胺的降幅较为明显。

The contents of putrescine were apparently higher than the control, then decreased with the increase of lead mass concentration and the time of treatment.

黄瓜幼苗叶片精胺和亚精胺在处理第5d时高于对照值，茎中精胺和亚精胺含量在处理第7d高于对照值，而其它时间内的都低于对照值，而且其含量均随铅质量浓度的增加而呈下降趋势；过氧化物酶活性变化与内源多胺含量（腐胺、精胺和亚精胺之和）的变化相似，表明铅胁迫能改变黄瓜幼苗内源多胺的含量和调节过氧化物酶活性，从而影响着黄瓜植株的生长。

Spermine and spermidine were detected in fairly high amounts in the muscle. In the liver and gonad putrescine was detected in the highest amounts, followed by spermidine and spermine.

肌肉中的多胺检出为精胺和亚精胺，肝脏和生殖腺中有较高浓度的腐胺及亚精胺和精胺检出。

Agmatine is the precursor of spermine and spermidine; however, neither of the two polyamines influenced morphine analgesia.

胍丁胺是精胺及亚精胺的合成前体。精胺和亚精胺均不影响吗啡的镇痛作用。

In this article, the method for detecting five kinds of biogenic amines by HPLC was established, and the contents of biogenic amines in Chinese rice wines and soy sauces were detected. In order to reduce the contents of BA, we inoculated Lactobacillus curvatus 6031 and Leuconostoc mesenteroides 51-5 D in sausage and the contents of BA and the microbial counts was studied during the fermention of sausage.

建立了高效液相色谱测定生物胺含量的方法，方法稳定性好、精密度高，回收率高，五种生物胺的回归方程分别为：y 尸胺=48.903x R 2=0.9996；y 组胺=36.105x R 2=0.9994；y 酪胺=29.865x R 2=0.9902；y 亚精胺=46.671x R 2=0.9967；y 精胺=31.239x R 2=0.9926，在2～40μg/ml的范围内R均大于0.99，检测限分别为：尸胺、组胺和亚精胺为0.05μg/ml，酪胺为0.1μg/ml，精胺为0.25μg/ml。
