Rheum australe D. Don

Cascaroside C is an anthraquinone compound. Cascaroside C can be isolated from the roots of Rheum emodi and Rhamnus purshianus DC.

10-Hydroxycascaroside D is an anthrone C-glucoside found in the roots and rhizomes of Rheum emodi.

10-Hydroxycascaroside C is an anthrone C-glucoside found in the roots and rhizomes of Rheum emodi.

10R-Chrysaloin 1-O-β-D-glucopyranoside is an anthrone C-glycoside and anthraquinone glycoside discovered in the roots and rhizomes of Rheum emodi.

2,5-Dimethylchromone-7-O-β-D-glucopyranoside is an orally active chromone glycoside found in the underground parts of Rheum australe. 2,5-Dimethylchromone-7-O-β-D-glucopyranoside shows a DPPH radical scavenging activity with an IC₅₀ value of 66.9 μM. 2,5-Dimethylchromone-7-O-β-D-glucopyranoside scavenges free radicals by providing hydrogen atoms through phenolic hydroxyl groups, inhibiting lipid peroxidation. 2,5-Dimethylchromone-7-O-β-D-glucopyranoside is promising for research of oxidative stress-related diseases such as inflammation and skin diseases.
