Composition of essential oil from aerial and underground parts of Geum rivale and G. urbanum growing in Poland.

A study of the composition of essential oils from aerial and underground parts of Geum rivale L. and Geum urbanum L. growing in Poland led to the identification of 130 compounds. The main compound of the essential oil from underground parts of G. urbanum was eugenol (69.2%), whereas cis-myrtanal (53.3%) was the major constituent of the essential oil from roots of G. rivale. The essential oils from aerial parts of the plants contained large amounts of aliphatic compounds with (Z)-3-hexenol (38.4%) being the dominant constituent of the essential oil from aerial parts of G. urbanum and 1-octen-3-ol (33.9%) from G. rivale.
