ABSTRACT
This article presents the results of studying the
component composition of essential oils of leaves and rhizomes of C. longa grown in Uzbekistan. The chemical composition of essential oils of vegetative
organs of the Curcuma longa (Zingiberaceae) plant introduced
in Uzbekistan was studied for the first time. Essential oils of the plant were
isolated by hydrodistillation, their chemical composition was studied by
chromatography-mass spectrometry. In the composition of essential oils of
leaves and rhizomes C. longa L., introduced in the Tashkent
oasis, found 27 and 16 components, respectively, among which the leaf is dominated by α-fellandren (33.79%), α-terpinolene
(24.28%), n-cymene (12.27%), eucalyptol (9.77%), and in the
rhizomes-6-(1,3-dimethyl-buta-1,3-dienyl)-1,5,5-trimethyl-7-oxa-bicyclo [4.1.0] hept-2-EN
(22.77%), α-curcumene (4.11%),
2,6,6,9-tetramethyl-tricyclo [5.4.0.0(2.8)] undec-9-EN (3.81%), α-zedren (1.14%), as well as 3
components that were not identified (the mass spectrum did not match the
library data) their mass fraction was 47.47%, 10.41% and 3.46%. The composition
of leaves and rhizomes of C. longa differ quantitatively and in
quality. For example, α-curcumene
in percentage content is more contained in rhizomes, and α-fellandren, which is the dominant content in leaves, is not found
in the underground part.
