Abstract

The invention discloses a high-efficiency preparation method for an acetyl harpagide reference standard product and belongs to the technical field of Chinese medicine modernization. The method comprises the following process steps of: A, extracting raw materials, namely performing refluxing extraction for 3 times by using 40 to 60 percent ethanol and 2 hours each time; B, enriching by using macroporous resin, namely removing impurities by using water and ethanol and eluting the target substance by using the ethanol; C, performing high-efficiency preparation and liquid phase separation, wherein the mobile phase is a 20 to 30 volume percent methanol solution and the detection wavelength is 210 nm; and D, recovering products, namely eluting by using the ethanol, concentrating and drying to obtain acetyl harpagide reference standard product with the purity of over 99 percent. The method is simple and quick, low in solvent consumption, high in yield and economic and environment-friendly, and has high economic value and academic value.
