Composition of the essential oil from the lemon balm growing in the neighborhood of Krasnoyarsk as indicated by gas chromatography-mass spectrometry data

摘要

Essential oil has been isolated from the above-ground part of the lemon balm growing in the neighborhood of Krasnoyarsk by the method of exhaustive water and steam distillation. Forty seven components, each with a content of more than 0.1% of whole oil, have been identified by GC-MS. The main oil components are citronellol (36.71%) and geraniol (27.20%). The oil also contains ten components with a content of more than 1% of the sum of all oil components: benzyl alcohol (1.67%), linalool (1.75%), citronellal (1.44%), neral (3.33%), geranial (4.39%), caryophyllene (3.73%), caryophyllene oxide (1.40%), dibutyl phthalate (1.36%), butylisobutyl ester of phthalic acid (2.45%), and phytol (2.55%). The composition of lemon balm oils from different regions of the world has been compared.
