Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C 14 H 8 O 2. Isomers include various quinone derivatives. The term anthraquinone, however refers to the isomer, 9,anthraquinone (IUPAC: 9,dioxoanthracene) wherein the keto groups are located on the central is a building block of many dyes and Appearance: yellow solid. Determination of anthraquinone contents in Cassia fistula leaves for alternative source of laxative drugs. Planta Med. 75 (09):PG doi: /s Sánchez, C. Anthraquinone (AQ) has been used in electron transfer studies in DNA. The focus of this dissertation is the synthesis of conjugates between AQ derivatives and 2’-deoxyadenosine (dA), which can be used to induce adenine oxidation in DNA. Different AQ derivatives were attached to dA via ethynyl or ethanyl linkers. Validation method for quantitative analysis of total anthraquinone glycosides by UV-vis spectrophotometric method Linearity A major component, rhein, was used as a standard for quantitative analysis of total anthraquinone glycosides. The calibration curve of rhein standard was made from 5 concentrations ( × to × g/ml). They.

The quantitative method was validated and applied to simultaneous determination of anthraquinone derivatives in 21 Radix et Rhizoma Rhei-based medicines. The limits of quantification were in the. Anthraquinone is a polycyclic aromatic hydrocarbon derived from anthracene or phthalic anhydride. Anthraquinone is used in the manufacture of dyes, in the textile and pulp industries, and as a bird repellant. 9,anthraquinone is an anthraquinone that is anthracene in which positions 9 and 10 have been oxidised to carbonyls. ADVERTISEMENTS: The anthraquinone glycosides are the ones whose aglycone component is a polyhydroxyanthraquinone derivative. The drugs having these glycosides possess cathartic activity. The polyhydroxyanthraquinone derivatives present in these drugs are chrysophanic acid (1, 8- dihydroxy- 3- methylanthraquinone), aloe emodin (1, 8- dihydroxy methyl . Anthraquinones (9,dioxoanthracenes) constitute an important class of natural and synthetic compounds with a wide range of applications. Besides their utilization as colorants, anthraquinone derivatives have been used since centuries for medical applications, for example, as laxatives and antimicrobial and antiinflammatory by:

The results of docking studies of anthraquinone derivatives (Dock score and net binding energy ΔG) on cyclooxygenase protein (4COX) using VLife MDS were as shown in Table 1. The interactions between the active amino acid residues of the protein and ligand molecules are enlisted and diagrammatically by: In an effort to develop an improved method for the determination of anthraquinone content in Correspondence: Hemanth Kumar Research and Formulation head Patanjali natural coloroma, Haridwar, India Tel: + E-Mail: [email protected] Qualitative and Quantitative Study of Anthraquinone Derivatives in the Root.   A quantitative determination method for total anthraquinone glycosides in Cassia Syrup was developed using direct spectrophotometry at analytical wavelength nm.
