High-Performance Liquid Chromatographic Determination of Lanatosides in Digitalis Lutea and Digitalis Ambigua Leaves[Reference: WebLink]

METHODS AND RESULTS:
An quantitative method for the determination of lanatoside A and Lanatoside B in Digitalis lutea and Digitalis ambigua leaves by high-performance liquid chromatography (HPLC) is described. The extract of dry leaf powder with chloroform:ethanol (1:2, v/v) was submitted to Sep-Pak cartridges prior to HPLC analysis. HPLC was performed on an ODS column using methanol:water (2:1, v/v) for Digitalis lutea and a phenylsilyl bonded silica column with acetonitrile:water (5:8, v/v) for Digitalis ambigua. The effluent was monitored by ultraviolet (UV) absorption at 220 nm. The quantitation was carried out by the internal standard method.
CONCLUSIONS:
The present method is sufficiently sensitive and reproducible to assay lanatosides in Digitalis leaves.
