New compounds from Rhodiola kirilowii

Abstract

Five compounds were isolated from root extracts of Rhodiola kirilowii: arbutin, epigallocatechin gallate, rhodiocyanoside A, fructopyrano-(1-4)- glucopyranose and lotaustralin. The first four compounds were found in this plant for the first time. Lotaustralin, salidroside, daucosterol and tyrosol were already described to be contained. Especially salidroside (as a Rhodiola marker compound) could not be detected in our samples. The structures were established by NMR studies. © Österreichische Apotheker- Verlagsgesellschaft m. b. H.
