This study was carried out to evaluate the inhibitory effect of aqueous, ethanolic and
methanolic extracts of the cladodes, flowers and fruits cactus plant (Opuntia ficus-indica)
with concentrations of (125, 250, 500, 1000) mg/ml against the isolat
ion of Aspergillus
niger fungus and compared it with aqueous solution of antibiotic (fluconazole) at
concentration 10 μg/ml. The study showed a difference in efficacy of studied extracts in
inhibiting the growth of studied fungus, The methanolic extract of flowers showed higher
inhibiting ratios (76.86, 81.32) % at concentrations (500, 1000) mg/ml respectively,
followed by the methanolic extract of cladode by inhibiting ratios reached (73.49, 76.14) %
at the previous concentrations, then followed by the ethanolic extract of flowers by
inhibiting ratio (40.96, 57.83) % at the same of previous concentrations, while inhibiting
ratio of fluconazole reached 65.66% at the used concentration, whereas the aqueous
extracts of flowers, fruits and cladode had the lowest effect by inhibiting ratios reached
(36.74, 23.49, 12.53) % respectively at concentration 1000 mg/ml.
The research was conducted in Al- Mokhtaria Research
Station, Agricultural Research Center, Homs, Syria during season
2016. The efficacy of some plant extracts (Melia azedarach L.,
Schinus molle L., Styrax officinalis L., Eucalyptus camaldulensis
De., Nerium oleander L.) were tested against Stephanitis pyri F.
(Tingidae: Heteroptera) and compared with traditional insecticides
(Cypermethrin, Chlorpyrifos Ethel).
This research has been applied to compare the efficacy of the use
of pre-planting with a sensitive variety of tomato OXN93 as a trap
crop with the use of the extracts of M. azedarach , E.
camaldulensis and C. maculatum where Diazinon a treated con
trol,
in reducing the infection and the reproduction rate of the root-knot
nematodes M. javanica on tomato (var. Bestona) in pots.
The research aims to study the effect of the treatment of the
eggplant seeds- pink local kind in some seaweed extracts to improve
the germination characteristics, as well as the study of their impact
on the growth of the resulting seedlings and their ability to
withstand the transplanting shock.
This study was conducted to determine the effect of lichen Evernia
prunastri extracts (acetone, ethanol, and chloroform) against the two
species of plant pathogenic fungi were Fusarium oxysporum, F.solani.
All extracts showed has inhibition influence evident in the growth of
fungal and germination of spores of two compared to the control.
The research aims to study the possibility of lengthening Remember
chicken meat, chilled by his treatment extracts the oily plant
cardamom, cinnamon, Zingiber and also curb the role of the
pseudomonas bacteria in chicken meat spoilage through
conservation radiator with anti impact during the oily extracts.
This research was conducted at Tal Shnan village, located at the eastern of Homs
city, Syria during 2012/ 2013 growing season, using hard local wheat cultivar,
Sham 5, to study the effect of seed rates (120, 150, 180, 210 kg/ha), spray with
differ
ent parts of sorghum water extracts using different, and weeding on wheat
yield and weeds accompany with the crop.
The research was carried out to evaluate the inhibitory efficacy of acetone, ethanol,
and chloroform of Evernia prunastri lichen with concentrations of (25, 50, 75, 100) mg/ml.
against three pathogenic species of Aspergillus sp. Which are: A. flavu
s, A. fumigatus and
A. niger . The efficacy varied among the four extracts, where both the acetonic and
methanolic showed noticeable inhibitory efficacy against the fungal species under study.
The efficacy increased of both extracts, at concentration (100) mg/ml growth of A. flavus,
A. fumigatus and A. niger was completely inhibited, whereas the inhibiton percentage for
ethanol extract reached (87.05, 78.82, 94.11)%, respectively at the same concentration. As
for the chloroform extract, it was the least effective, where the percentage at (100) mg/ml
concentration reached (68.23, 74.11, 62.35) %, respectively, compared to the control.
Depending on these results, the extracts lichen of Evernia prunastri could be used
as natural products to treat fungal infections in the future.
The bio-effect of anise oil and its fruit extracts(alcoholic and
aqueous extract) to control the cowpea beetle, Callosobruchus
maculatus that infest stored leguminous crops was investigated. The
study was conducted according to three treatments: e
vaporation,
direct spray of insects and food spray. The anise oil was used at
different concentrations from 0.05 to 5%. Whereas, the aqueous and
.alcoholic fruit extracts were used as 30%.
Activity of Ziziphora tenuior L. leaves organic extracts against four pathogenic
bacteria, which were isolated from clinical samples and prepared from Al-Assad hospital
laboratory in Lattakia, were tested by disc diffusion method through 2014.
Res
ults showed that Ziziphora tenuior L. leaves extracts have antibacterial activity
against all Gram positive and negative bacteria. Inhibition zones were recorded between
9mm against Pseudomonas aeruginosa and 44mm against Staphylococcus aureus at
concentration of 200mg/ml for the methanolic extract. Whereas the inhibition zones for the
ethanolic extract were recorded between 7mm at concentration of 40mg/ml against
Streptococcus sp. and 34mm at concentration of 200mg/ml against Staphylococcus aureus.
These results represent the importance of Ziziphora tenuior L. as a source of natural
substances counteraction of pathogenic bacteria.
