در چند سال اخیر با توجه به اهمیت مسایل زیست محیطی و درک جایگاه واقعی این مسئله، استفاده از ترکیب های گیاهی در بین محققان به عنوان یکی از روش های جایگزین برای متیل بروماید و فسفین مطرح شده است. در این تحقیق اثر حشره کشی و دورکنندگی عصاره میوه سرو (thuja orientalis)، پوسته سبز گردو (juglans regia) و برگ بنه (pistacia khinjuk) روی حشرات کامل شپشه آرد (tribolium confusum) و شپشه دندانه دار برنج (or...
The phytochemicals of aqueous, methanol, ethanol and n-hexane crude extracts GC-MS the essential oils obtained by hydro-distillation solvent extraction methods Ocimum sanctum leaves grown in Nigeria were determined present study. Phytochemical analysis showed that contained saponins, terpernoids, cardiac glycosides, steroids, alkaloids, phlobatannins tannins. highest contents phenol steroid fou...
Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...
The yeast Trichosporon mucoides, grown on either glucose or phenol, was able to transform biphenyl into a variety of mono-, di-, and trihydroxylated derivatives hydroxylated on one or both aromatic rings. While some of these products accumulated in the supernatant as dead end products, the ortho-substituted dihydroxylated biphenyls were substrates for further oxidation and ring fission. These r...
The title compound, C(23)H(25)N(3)O(2), was obtained as an inter-mediary in the preparation of non-symmetric tertiary diamines. The mol-ecular structure presents T-shaped spatial form, in which the pyrimidine ring exhibits a chair conformation. The pyridyl ring is almost perpendicular to the phenyl rings with dihedral angles of 80.17 (8) and 76.03 (2)°. The phenol and amine groups are involved ...
3,4-dihydro-3-phenyl-2H-1,3-benzoxazines derived from phenol-, resorcinol-, and phloroglucinol give monomers with one, two, and three oxazine units at a single benzene ring, respectively. Aside from the synthesis and characterization of such multifunctional benzoxazines, reactivity and polymerization behavior is studied in dependence of the oxazine functionality. Monomer reactivities are direct...
In the title compound, [Cu(C(13)H(7)BrCl(2)NO)(2)], or CuL(2) {where HL= 2-[(E)-(2-chloro-phenyl-imino)-meth-yl]-6-bromo-4-chloro-phenol}, the Cu(II) atom is located on an inversion center and has a square-planar coordination. In the crystal, complex mol-ecules are linked via Cu⋯Cl inter-actions [2.9933 (11) Å], forming a two-dimensional network parallel to the bc plane. They are also Cl⋯Cl int...
In the title compound, C(14)H(12)N(2)O(2)S, the amino-phenol and the benzoyl groups adopt a syn-anti configuration with respect to the thiono C=S group across the thio-urea C-N. The dihedral angle between the mean planes of the benzoyl and hy-droxy-phenyl rings is 36.77 (8)°. The mol-ecules are stabilized by intra-molecular N-H⋯O hydrogen bonds. In the crystal, weak inter-molecular C-H⋯O, O-H⋯S...
The title compound, C(12)H(8)N(2)O(5), was obtained by the reaction of 1-chloro-2,4-dinitro-benzene and phenol in the presence of potassium carbonate. The nitro-substituted benzene ring lies on a mirror plane, with one NO(2) group in the same plane and the other disordered across this plane. The phenoxy-benzene unit is placed perpendicular to this mirror, resulting in an exact orthogonal relati...
