ISOLATION AND IDENTIFICATION OF ACTIVE SULFATE

Isolation and Identification of Ginger Essential Oil

ABSTRACT: The essential oil of plant material is the fraction isolated by means of several methods such as liquid carbon dioxide, microwaves and low or high pressure distillation employing boiling water or hot steam and is chemically defined as terpenoids namely monoterpene and the oxygenated form. Since these compounds might be employed as flavour contributors due to their chemical nature, it ...

Isolation and characterization of a phage active against streptomyces griseus

Isolation of Androsterone Sulfate

It has long been recognized that many of the steroids, including the androgens, are excreted in urine in conjugation with other substances which render them not only more water-soluble but also neutralize their physiological activity to a great extent. In 1936 Cohen and Marrian (1) isolated estriol glucuronide, the conjugated form of estriol, from the urine of pregnant women and in 1936 Venning...

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...

synthesis and characterization of potentially biological active cyclometallated organoplatinum(ii) complexes

this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
