The essential oil obtained from Thymus Serpyllum L. var. Przewalskii Komarow by steam distillation was fractionally distilled under a reduced pressure by which the chief component was found to be thymol, comprising about 35%. Other components found were linalool, p-cymene, α-pinene, and a trace of d-borneol. The oil did not contain carvacrol but it could be used in place of thymus oil.
