title: Quantitative determination of salidroside and tyrosol from the underground part of Rhodiola rosea by high performance liquid chromatography.
abstract: A reversed-phase high performance liquid chromatographic method was developed to determine salidroside and tyrosol simultaneously in the Rhodiola rosea. The optimum condition was Nova-Pak C18 as stationary phase, 6.5% methanol in water as mobile phase and detection at UV 225 nm. The identification was carried out by comparing the retention time and IC/MS spectrum of the relevant peaks with those of isolated standards. The contents of salidroside and tyrosol in the samples gathered from various area in China were ranged over 1.3-11.1 mg/g and 0.3-2.2 mg/g, respectively.
