Abstract

|
From Korean cultivated peony root, paeoniflorin and albiflorin, which are generally considered to be principal components of peony root, were isolated by silicagel column chromatography. Their structures were identified by spectroscopic methods (UV,;FT-IR,;^1H{cdot}^{13}C-NMR) and their purities were 98% and 93%, respectively. The concentrations of paeoniflorin and albiflorin in ten Korean cultivated peony lines were determined by reverse phase HPLC. The concentrations of paeoniflorin ranged from 1. 56 to 4.04% and those of albiflorin ranged from 0.04 to 1. 98% in ten Korean cultivated lines. In the ten cultivated lines, the concentrations of albiflorin in Punggi lines were higher than other lines.
