Abstract:

The current study was performed to examine the qualitative and quantitative
composition of the essential oil, n-hexane and ethanol extracts from the rhizomes of Iris
dichotoma Pall. for their volatile content. The essential oil was particularly found to possess
the most rich composition, while the latter extracts (n-hexane and ethanolic ones) consisted
of various fatty acid esters. GC and GC-MS analyses of the oil resulted in the identification
of 28 components. Among them myristic acid (13.67 %), methyl myristate (9.08 %), and α-
terpineol (2.42 %) were found to be the dominant compounds. The qualitative composition
of both n-hexane and ethanol extracts of Iris dichotoma Pall., obtained by pressurized liquid
extraction, was similar and revealed the presence of 6 components, which were identified as
natural products with methyl myristate as the major one (22.47 % and 10.18 % in ethanolic
and n-hexane extracts, respectively).
