title: [Isolation and determination of homoeriodictyol-7-O-beta-D-glycoside in Viscum coloratum].
abstract: The homoeriodictyol-7-O-beta-D-glycoside was isolated from Viscum coloratum and identified by mass spectrometry and nuclear magnetic resonance (NMR) (1H NMR and 13C NMR). A method for determination of homoeriodictyol-7-O-beta-D-glycoside in Viscum coloratum was developed by using a Kromasil C18 column (200 mm x 4.6 mm i.d., 5 microm) with a mixture of acetonitrile and 0.5% glacial acetic acid solution (18:82, v/v) as mobile phase at a flow rate of 1.0 mL/min. The detection wavelength was set at 284 nm and temperature was set at 30 degrees C. The volume of injection was 10 miccro L. Good linear relationship (r = 0.9997) between the mass concentration and the peak area of homoeriodictyol-7-O-beta-D-glycoside was obtained in the range of 1.0-32.0 mg/L. The recoveries were found to be in the range of 96.0%-100.1%. The results of the experiments demonstrated that the established method is rapid and simple with good accuracy and reproducibility. The method is suitable for the quality control of Viscum coloratum from different sources.
