去枝的日本薄荷（Mentha arvensis L.，亚种单萼草piperascens Holmes）进行标记以允许随后的年龄鉴定。对不同叶龄的叶片进行蒸馏，测定油的数量和质量。大部分的油和它的主要成分，薄荷醇，合成在第一个2周的增长，而薄荷酮和α-蒎烯的百分比组成的油随着年龄的下降2周后。一个显着的百分比油含量下降发生在老叶表明，通过衰老叶片损失造成的损失比干物质的油。新老叶比例对油成分有显著影响。这是首次报道日本薄荷单株叶油成分。
Leaves of debranched Japanese mint (Mentha arvensis L., subsp. haplocalyx Briquet var. piperascens Holmes) were marked to allow subsequent identification for age. Leaves of different age groups were distilled for determination of quantity and quality of oil. Most of the oil and its principal component, menthol, were synthesized during the first 2 weeks of growth, while menthone and the a-pinene percentage composition of the oil declined with age after 2 weeks. A significant decrease in percentage oil content occurred in older leaves indicating that leaf loss through senescence caused less loss of oil than of dry matter. Proportion of young to old leaves had a significant effect on oil composition. This is believed to be the first report on oil composition of leaves from single plants of Japanese mint.
