Summary: | This study was performed to investigate the constituents, in vitro antifungal activity and phytotoxicity potential of the essential oil from
Juniperus polycarpos
var.
turcomanica
leaves. The essential oil was analyzed by GC–FID, and GC/MS, which predominantly contains α-pinene (51.21%), germacrene–B (4.80%), and
∆
-cadinene (2.56%). The antifungal activity of the essential oil against some phytopathogenic fungi, including
Alternaria alternata
,
Colletotrichum trichellum, Curvularia fallax
,
Cytospora sacchari
,
Fusarium oxysporum
, and
Macrophomina phaseolina
was performed through disk diffusion and agar dilution assays. The essential oil of
J. polycarpos
var.
turcomanica
had high antifungal activity against tested phytopathogenic fungi. The most susceptible fungi to the essential oil were
C. trichellum
in agar dilution and
M. phaseolina
and
C. fallax
in disk diffusion methods, whereas, the most resistant fungus to the essential oil was obtained from
A. alternata
in both assays. Screening methods had an influence on antifungal activity of the essential oil as most of the tested fungi in this study were shown to be more resistant in disc diffusion methods. According to the phytotoxic assay results, the essential oil from
J. polycarpos
var.
turcomanica
had high phytotoxicity against three species of weeds, including
P. oleracea
L.,
A. retroflexus
L., and
D. stramonium
L. The results of this research suggest that the herbicidal and antifungal activities of the essential oil from
J. polycarpos
var.
turcomanica
can be attributed to its major group of constituents, monoterpenes hydrocarbons. |
