14CO2 实验表明，薄荷合成单萜仅发生在幼嫩的组织中，也就是仍在扩张的叶子中。这些幼叶中第一个萜烯的形成是一个快速的过程，在不到半小时的时间内就形成了几种标记的萜烯。其中包括不饱和酮；将标签融入薄荷酮需要更长的时间；饱和酒精薄荷醇的贴标需要几天时间。对单枝叶对中萜烯分布的分析表明，从幼叶中的不饱和酮和薄荷呋喃到老叶中的薄荷醇和乙酸薄荷酯有规律的连续性。通过使用标记的萜烯作为叶片的底物，可以证明胡椒烯酮到胡椒酮、胡薄荷酮到薄荷酮以及胡薄荷酮到薄荷呋喃的转化。
Experiments with 14CO2 have shown that the synthesis of monoterpenes by peppermint occurs only in the young tissue, in leaves which are still expanding. The formation of the first terpenes in these young leaves is a rapid process, with several labeled terpenes formed in less than a half hour. Among these are unsaturated ketones; incorporation of the label into menthone takes somewhat longer; and several days are required to label the saturated alcohol menthol. Analysis of the distribution of terpenes through the leaf pairs of a single shoot shows a regular succession from unsaturated ketones and menthofuran in the young leaves to menthol and menthyl acetate in the old leaves. By using labeled terpenes as substrates with leaf slices, it is possible to demonstrate the conversion of piperitenone to piperi-tone, of pulegone to menthone, and of pulegone to menthofuran.
