They are chrysophanol, aloe–emodin and rhein and are present in the drug both in the free as well as in the combined state. The free anthraquinone derivatives amount to 1.12 %, while the combined 4.5 %, Rhaponticin, Physcion and C–C–glycosides are found absent in Indian Rhubarb. Further, the anthraquinone derivatives are present in the oxidised form.
