説明

Sesquiterpene hydrocarbons from the seed oil of Iris tectorum M. were investigated. Fractionation of the hexane extract of the seeds by column chromatography on activated alumina and steam distillation gave monoterpene-free hydrocarbons which showed approximately thirty peaks by capillary gas chromatography. A combination of techniques including a silver nitrate addition procedure, rectification and silver nitrate-impregnated silica gel column chromatography was used to separate the sesquiterpenes.<BR>Twenty-four compounds could be identified on the basis of spectral data (IR, NMR, GC, GC-MS) and chemical transformations. The main components were germacrene D (45%), alloaromadendrene (12%), δ-, γ-cadinene (13%), and β-caryophyllene (7%). These sesquiterpenes in Iridaceae plants were characterized for the first time in the present research.
