Isolation and Identification of Flavonoids in Iraqi <i>Rheum ribes</i> Root

The aim of the study was isolate and identify the flavonoids in Iraqi Rheum ribes root, the results obtained from the HPLC analysis indicate that the Iraqi Rheum ribes root contain different types and concentration of flavonoids which include 29.9056 μg/g aloe-emodin, 252.880 μg/g emodin, 76.8493 μg/g chrysophanol, 56.1317 μg/g physician and 49.2098 μg/g rutin, while the types of flavonoids in the isolated extract of flavonoids from the Iraqi Rheum ribes root were 146.096 μg/g aleo-emodin, 37.174 μg/g emodin, 11.525 μg/g chrysophanol, 20.010 μg/g physcion, 30.271 μg/g rutin. The identification the all types of flavonoids in isolated flavonoids from the Iraqi Rheum ribes roots as compared with the flavonoids in the crude roots refers to the efficiency of the method for isolation of flavonoids from the roots of plant.
