The anthocyanins of Siahe Sardasht variety (Vitis vinifera L. var. S.S.) were extracted from freezed samples and were purified by adsorption on cation-exchange resin column. Individual pigments were separated by TLC on cellulose plates. Monomeric anthocyanin content that was determined by pH-differential, was 1740.11±3.58 mgL?1 (based on malvidin 3-glucose). Five major pigments were identified ...

The title thio-urea mol-ecule, C(13)H(18)N(2)OS, adopts a folded conformation due to the steric hindrance of the two ethyl groups and the acetyl group. In the crystal structure, the acetyl O atom is not involved in hydrogen bonding, but inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers.

niosomes are non-ionic surfactant vesicles that have potential applications in the delivery of hydrophilic and hydrophobic drugs. the topical form of n-acetyl glucosamine (nag) recently has been considered in the treatment of hyperpigmentation disorders due to its inhibitory effect on thyrosinase enzymes in melanocytes. to improve nag penetration into the skin we formulated the drug in niosomes...

schizophrenia and various neurological disorders have some signs and symptoms. visual hallucinations are one of such disorders. the related studies in some diseases for example parkinson disease and lewy body dementia indicate that acetylcholine (ach) plays a significant role in neuropsychiatric manifestation and its association with visual hallucination; therefore, visual hallucinations occur ...

The title material, [Zn(C(5)H(7)O(2))(2)(C(9)H(9)NO)], was synthesized by the treatment of bis-(acetyl-acetonato)zinc(II) monohydrate with 2-phenyl-2-oxazoline. The Zn atom is coordinated by two chelating acetyl-acetonate groups and one oxazoline ligand in the apical position of a slightly distorted square-pyramidal metal-ligand geometry.
