New antioxidant phytopreparation from Rumex thyrsiflorus roots. III

摘要: We identified in the phytopreparation caffeic, gallic, and p-hydroxybenzoic acids; phloroglucinol, hydroquinone, pyrogallol, quercetin, myricetin, rutin, isorhamnetin, isorhamnetin-3-O-rutinoside, myricetin-3-O-rhamnoside, (+)-catechin, (-)-epicatechin gallate, chrysophanol, emodin, physcion their glycosides; one of which was 5-methoxyphyscion 4-O-glucoside, a new compound for sorrels. The structure this established using UV, IR, PMR spectra; products total acid hydrolysis, comparison with literature [3, 11]. antioxidant activity studied at Scientific-Research Center Chemistry (Pakistan) by testing DPPH (1,1-diphenyl-2-propylhydrasil radical) as before [12]. It slightly more active (95%) than standard propylgallate (94.12%). can be recommended use. roots R. thyrsiflorus F. used raw material its production. This expands variety natural antioxidants.
