Abstrakt: AbstractThe oils of Lomatium dissectumvar. dissectumand L. dissectumvar. multifidumwere analyzed by GC and GC/MS. β-Phellandrene/limonene (25.3%), β-caryophyllene (10.8%), palmitic acid (6.6%), (E)-β-ocimene (5.4%), linolenic acid (4.7%); palmitic acid (15.3%), octanol (9.0%), octyl acetate (5.3%), β-caryophyllene (4.1%), linolenic acid (4.8%); myrcene (19.0%), 4-methylpentyl 2-methylbutyrate (13.9%), limonene (5.8%), α-bisabolol (5.1%), cuparene (5.0%), 4-methylhexyl 2-methylbutyrate (4.2%) constituted the major components of the respective hydrodistilled oils from the fruits, uppers (stems and leaves) and roots of L. dissectumvar. dissectum.The corresponding oils from L. dissectumvar. multifidumshowed, palmitic acid (12.1%), palmitoleic acid (8.9%); decyl acetate (7.6%), linolenic acid (7.4%), linoleic acid (6.9%); (Z)-3-hexenol (18.5%), palmitic acid (8.6%), myrcene (6.0%), decyl acetate (4.9%), longifolene (4.2%); and myrcene (23.1%), longifolene (20.4%), limonene (6.0%), palmitoleic acid (5.1%) as the major components. The root oils of both varieties contained nearly 4% of a new hydrocarbon, (E)-2-methyl-3-octen-5-yne.
