Alaternin, cassiaside and rubrofusarin gentiobioside, radical scavenging principles from the seeds of Cassia tora on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical.
Radical scavenging principles on 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical were isolated from the seeds of Cassia tora L. Assignments of the 1H- and 13C-NMR data showed the active components to be an anthraquinone, alaternin and two naphthopyrone glycosides, nor-rubrofusarin-6-beta-D-glucoside(cassiaside) and rubrofusarin-6- -D-gentiobioside. Alaternin showed more potent radical scavenging effect than the others.
