Dyeing Behavior of Chrysophanol on Polyester Fiber

Advanced Materials Research, 2011
The dyeing properties of chrysophanol on polyester (PET) were investigated. Chrysopahnol was stable with the pH range of 3 to 7. And in this pH range, the hue of Chrysophanol of dyed polyester showed very little change. The K/S values increased significantly when the temperature was raised from 90°C to 110°C, and if the temperature was 110°C, the ...

Chrysophanol facilitates long-term neurological recovery through limiting microglia-mediated neuroinflammation after ischemic stroke in mice.

International Immunopharmacology, 2022
BACKGROUND Inflammation plays an important role in ischemic brain injury and affects brain recovery and neuroplasticity. Chrysophanol (CHR), has attracted attention for its protective effects through immunomodulatory and anti-inflammatory properties ...

UV and IR spectra of anthraquinone and chrysophanol derivatives

Journal of Applied Spectroscopy, 1967
1. The electronic absorption spectra of nitrogen-containing derivatives of anthraquinone and chrysophanol have an aromatic character. 2. Absorption bands at 2700 and 3200 A are characteristic for the nitrogen-containing derivatives of anthraquinone, whereas an absorption band with a maximum at 4300 A is characteristic for the derivatives

Kobayashi's Aryne Precursor for the One-Step Synthesis of Anthraquinones and Its Application to the Total Synthesis of Chrysophanol, Danthron, and Physcion.

Journal of Organic Chemistry
A one-step synthetic method to access medicinally essential anthraquinones has been developed by reacting Kobayashi's aryne precursors with 3-sulfonylphthalides following [4 + 2] Hauser-Kraus annulation reaction. The developed method has been implemented

A convenient synthesis of isotopically labelled anthraquinones, chrysophanol, islandicin, and emodin. Incorporation of [methyl-2H3]chrysophanol into tajixanthone in Aspergillus variecolor

Journal of the Chemical Society, Chemical Communications, 1987
Cycloaddition reactions of labelled 6-methoxy-3-methyl-2-pyrone (1) with naphthoquinones provide the common fungal anthraquinones, chrysophanol (2), islandicin (3), and emodin (4) suitably labelled for biosynthetic studies, as demonstrated by synthesis and incorporation of [methyl-2H3]chrysophanol into the xanthone metabolite, tajixanthone (17) in ...

No induction of chromosomal aberrations in Chinese hamster ovary cells by chrysophanol

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2001
Chrysophanol is an anthraquinone which occurs in several herbal drugs, e.g. senna, a commonly used laxative. As there are only limited data on its clastogenic potential we have investigated its capability to cause chromosomal aberrations in the Chinese hamster ovary cell assay.
