Abstract
Ledum palustre L. has been actively used in ethnomedicine in Mongolia, China and Russian Far East (indigenous peoples: Udege and Evenki) for centuries, as an antioxidant, immunomodulating, anti-inflammatory, vitality-restoring agent. L. palustre contain various phenolic compounds and fatty acids with valuable biological activity. This plant is especially actively used in shamanic and healing practices among the Udege people living in the Primorsky and Khabarovsk Territories, Russia. We used the method of extracting biological substances by incense from the L. palustre using the methods of shamanic practices thanks to the direct participation of the shaman of the Udege people Vasily I. Dunkay. Tandem mass-spectrometry was applied to detect target analytes. 113 different biologically active components have been identified in the L. palustre extracts. For the first time, compounds from the group of cannabinoids were identified in this plant. Also, 74 compounds from other chemical groups were identified for the first time.
