أُجريت هذه الدراسة لتقييم الفعالية التثبيطية للمستخلصات المائية, الإيتانولية و الميتانولية لسوق, أزهار و ثمار نبات الصبار (Opuntia ficus-indica) بتراكيز (125, 250, 500, 1000) ملغ/مل إزاء عزلة من فطر Aspergillus niger و مقارنتها مع المحلول المائي للصاد الحيوي (الفلوكونازول) بتركيز 10 مكغ/مل. بينت الدراسة اختلاف فعالية المستخلصات المدروسة في قدرتها التثبيطية تجاه الفطر المدروس, حيث أظهر المستخلص الميتانولي للأزهار أعلى نسبة تثبيط (76.86,81.32 )% عند التركيزين (500,(1000 ملغ/مل على التتالي, تلاه المستخلص الميتانولي للساق بنسبة تثبيط بلغت (73.49, 76.14) % عند التركيزين السابقين, و من ثم المستخلص الإيتانولي للأزهار بنسبة تثبيط 40.96), (57.83 % عند ذات التركيزين السابقين, في حين بلغت نسبة تثبيط الفلوكونازول 65.66% عند التركيز المستخدم, بينما كانت المستخلصات المائية للأزهار, الثمار و الساق الأقل تأثيراً بنسب تثبيط بلغت على التتالي (36.74, 23.49, (12.53 % عند التركيز 1000 ملغ/مل.
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 isolation 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 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.
In this research was studied the effect of different concentrations of (ethanolic –
methanolic – acetonic) extracts of Apium nodiflorum on growth of fusarium moniliforme
all extracts revealed clear inhibitory effect against this Fungi.
The inhibit
ory effect differenced as difference of parts of plant and the difference of
using concentrations from extract and a kind of solvent.
The MIC of different extracts ranged between 0.02 and 0.1 g/ml , The Acetonic
extract of stem was the more activity comparing with the other parts of plant inhibition was
completed at (0.02 g/ml) concentration.
For methanolic extract, the extract of whole plant and flowers was more activity and
the MIC was 0.08 g/ml for etanolic extract of flowers recorded the highest percentage of
inhibition incomparing with. The other parts of plant and it reached 0.06 g/ml.
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 antibacterial activity of Inula viscosa L. leaves extracts against some pathogenic bacteria, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method.
Results showed that water extracts had antibacte
rial activity against all Gram positive and negative bacteria. The diameters of inhibition zones were between 9 mm against Pseudomonas aeroginosa and 41 mm against Proteus vulgaris.
All Gram positive bacteria showed sensitivity to all organic extracts, so they had antibacterial activity, while Gram negative bacteria showed resistance to chloroform extract except for the one of Klebsiella pneumoniae with an inhibition zone of 12 mm, and resistance for dichlormethan extract except for Pseudomonas aeruginosa with an inhibition zone of 15 mm. there was resistance for diethyl extract except for Serratia marcescens with an inhibition zone of 32 mm.
Ethyl acetate extract had antibacterial activity against all bacteria. Ethanol, methanol and acetone extracts showed antibacterial activity against all bacteria except for Escherichia coli with an inhibition zone of 10 mm.
This study indicated that water and organic Inula viscosa L. leaves extracts had antibacterial activity against pathogenic bacteria which also was tested, especially water extract, ethanol, methanol, ethyl acetate and hexane extracts. So the Inula viscosa L. leaves extracts may be sources for natural antibiotic in future.
A Study was carried out to evaluate the ability of the methanolic, hydro and oily
extractions of anise seeds (Pimpinella anisum L.) to inhibit the growth of the pathogenic
fungi Fusarium oxysporum and Aspergillus niger. The results showed a good in
hibition
ability of the alcoholic and hydro extractions on the growth of the studied fungi. The
inhibition ability differed due to the used concentrations. When the methanolic extraction
was used by concentrations (2, 4, and 6) mlg/ ml at the seventh day, the inhibition ability
was (42.5, 50.6 and 64.4)% of the fungus F. oxysporum, respectively. And was (23.6, 42.7
and 55.1)% of the fungus A. niger, respectively. Whereas when the hydro extraction was
used by the same concentrations, the inhibition ability was (59.2, 65.3 and 70)%
respectively for the fungus F. oxysporum, and (46.1, 58 and 61)% for the fungus A. niger,
respectively. The oily extraction showed high inhibition ability, where the inhibition rate
was 100% when the extraction was used by the two concentrations 50 and 75 μl for both
two studied fungi.
