| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

High-Performance Liquid Chromatographic Determination of Lanatosides in Digitalis Lutea and Digitalis Ambigua Leaves
Journal of Liquid Chromatography, 1994,17(20): 4451-61.
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. The present method is sufficiently sensitive and reproducible to assay lanatosides in Digitalis leaves.
