Research Area: Inflammation
Biological Activity:
Rheochrysidin (Physcion; physcione; parietin) is one of the major components of Da-Cheng-Qi decoction used in the treatment of inflammation. A liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of the 10 major components of Da-Cheng-Qi decoction (rhein, emodin, aloe-emodin, chrysophanol, rheochrysidin, naringin, naringenin, hesperidin, magnolol and honokiol) in dog plasma. Plasma samples were spiked with internal standard (ibuprofen), acidified with HCl and extracted twice by liquid-liquid extraction using ethyl acetate. The linear range of the calibration curves was 5000-19.53 ng/mL for rhein; 400-3.13 ng/mL for emodin; 800-3.13 ng/mL for aloe-emodin, chrysophanol, naringin, naringenin, hesperidin, magnolol and honokiol; 160-0.63 ng/mL for rheochrysidin. The lower limit of quantification was: 19.53 ng/mL for rhein; 3.13 ng/mL for emodin, aloe-emodin, chrysophanol, naringin, naringenin, hesperidin, magnolol and honokiol; 0.6 3 ng/mL for rheochrysidin (Physcio; physcione; parietin).

Biochem/physiol Actions
Anthraquinone-derivative found in medicinal herbs.
Application
Physcion can be used to study antibiotics, antifungals, bioactive small molecules and cell biology. Physcion has been used in a study to test the cytotoxicity of juglanthraquinone C on human cancer cells. Physcion has also been used in a study that investigated the metabolic regulatory effects of Rheum undulatum in a high-fat diet model.

P398000 

A natural anthraquinone derivative, on the infection process of Blumeria graminis on wheat. Physcion is one of the important active ingredients of ethanol extract from the roots of Chinese rhubarb (Rheum officinale) for controlling powdery mildew.

CHEBI:38167 

A dihydroxyanthraquinone that is 9,10-anthraquinone bearing hydroxy substituents at positions 1 and 8, a methoxy group at position 3, and a methyl group at position 6. It has been widely isolated and characterised from both terrestrial and marine sources.
