synthetic sulphonated anthraquinones are the raw materials used for producing a large palette of synthetic dyes, and microorganisms have a limited ability to decompose them, hence they are one of the important environmental pollutants. in order to study the ability of plants to remove this pollutant from the environment, corn, as a plant not containing any natural anthraquinones and common sorr...

Anthraquinones are a class of aromatic compounds with a 9,10-dioxoanthracene core. So far, 79 naturally occurring anthraquinones have been identified which include emodin, physcion, cascarin, catenarin, and rhein. A large body of literature has demonstrated that the naturally occurring anthraquinones possess a broad spectrum of bioactivities, such as cathartic, anticancer, anti-inflammatory, an...

Xiexin decoction (XXD), a classic pyretolysis formula, is composed of Rhei Rhizoma (DH), Radix Scutellaria (HQ) and Coptis Chinensis (HL) and is commonly used in the clinical setting. The aim of this study was to investigate the pharmacokinetic differences of the five anthraquinones in rats after oral administration of XXD and different combinations of its constituent herbs. Twenty rats were ra...

The redox behaviour of two potential anticancer anthraquinones, 9,10-anthraquinone and 2-chloromethyl-9,10-anthraquinone was investigated in a wide pH range. Cyclic voltammetry based assay was developed for the assessment of the effect of medium, substituents, potential scan rate and number of scans on the voltammetric response of anthraquinones. The electrode reaction mechanism was suggested o...

Root decoctions of anthraquinone-containing plants are often taken as postpartum tonic and aphrodisiac. Anthraquinones are known for their diverse biological activities, especially antioxidant and anticancer. A series of 35 anthraquinones was generated by isolation from Rubiaceae plants and synthesis. Their UV/vis spectrum depends on the nature and relative positions of auxochromic substituents...

The cell suspension cultures were established from leaf, fruit and root explants of Indian Mulberry (Morinda citrifolia) for the production of medicinally important secondary metabolites, anthraquinones, flavonoids and phenolics and the effect of subculture on these secondary metabolites was studied. The MS medium formulated with NAA, BA and Kinetin was found to be effective to produce anthraqu...

Noni has been used in traditional medicine and as food for thousands of years. While the fruits serve as food and internal medicine, leaves were traditionally used only topically. In recent years, concern regarding the possible content of anthraquinones in noni has led to scrutiny by the European Food Safety Authority. Little research existed on the content of anthraquinones in different noni p...

The aim of this work was to study the phytochemical and antifungal activity of anthraquinones and root and leaf extracts of Coccoloba mollis on phytopathogens. The chemical analysis of ethanolic extracts showed a mixture of long-chain hydrocarbons, carboxyl esters and 3-taraxerone in the leaf extract. Two anthraquinones (emodin and physcion) were isolated and identified from the root extract. P...

In the present study, we aimed to prepare rhubarb total anthraquinones oral colon-specific drug delivery granules (RTA-OCDDGN) for delivering rhubarb free anthraquinones to colon. RTA-OCDD-GN was successfully prepared through a double-layer coating process using chitosan as an inner layer and Eudragit S100 as an outer enteric coating layer. The pharmacodynamics and toxicological results showed ...
