Phytochemical characters were evaluated in a five-year-old lemon balm collection consisting of 15 and 13 subspecies and accessions, respectively. Stems were lower in essential oil than leaves. First cut leaves (June) gave more oil than those of the second cut (August). Subspecies plants had leaf oils rich in geranial, neral and citronellal in various proportions in the first cut. However, in the second cut the oils from all accessions appeared very similar with 80-90% geranial plus neral. Leaf oils of subsp. contained sesquiterpenes (β-caryophyllene, caryophyllene oxide, germacrene D) and also further monoterpenes in the second cut. Leaves had higher rosmarinic acid (RA) contents than stems. More RA was in subsp. than subsp. leaves. First cut leaves were richer in RA than those from second cut. Total phenolics and antioxidant parameters showed that lemon balm is a valuable source of plant antioxidants.
在一个五岁的柠檬香脂收藏中评估了植物化学特性，其中包括 15 个亚种和 13 个亚种和品种。茎中的精油含量低于叶片。第一次收割的叶子（6 月）比第二次收割的叶子（8 月）含油量更多。亚种植物的叶子油在第一次收割时富含香叶醛、橙花醛和香茅醛，比例各不相同。然而，在第二次收割中，所有品种的油都非常相似，含有 80-90%的香叶醛加橙花醛。亚属 的叶子油含有倍半萜（β-丁香烯、丁香烯氧化物、大根香叶烯 D）和第二次收割时的进一步单萜。叶子中的迷迭香酸（RA）含量高于茎。亚属 的叶子比亚属 的叶子含有更多的 RA。第一次收割的叶子比第二次收割的叶子含有更多的 RA。总酚和抗氧化参数表明，柠檬香脂是植物抗氧化剂的宝贵来源。
