概要
An activity-guided isolation and purification process was used to identify the DPPH free radical scavenging components of Rheum emodi. The activity-guided isolation revealed that eugenol, gallic acid, quercetin, rutin, epicatechin, desoxyrhapontigenin, rhapontigenin and mesopsin are the major phenolic compounds responsible for the antioxidant activity of the roots of R. emodi.
