Proline content of genuine wines from different areas is usually over 200 mg/1; a sample contained 1.920 mg/1; some samples has shown a lower content, with a minimum of 76 mg/1. No correlationship has been established between proline content and wine origin and age. Spectrophotometric method gives results markedly higher, in some cases, than give ion-exchange chromatogrpahy.
不同产地的纯正葡萄酒的脯氨酸含量通常超过200毫克/升；一个样本含量为1920毫克/升；一些样本含量较低，最低为76毫克/升。脯氨酸含量与葡萄酒的产地和年份之间未建立相关性。分光光度法得出的结果在某些情况下明显高于离子交换色谱法得出的结果。
