The invention provides a method for preparing oxytroflavoside A, B, C, D, E, F and G from oxytropis falcate bunge. The method comprises the following steps: (1) extraction: pulverizing the oxytropis falcate bunge, extracting the oxytropis falcate bunge with ethanol to obtain an extracting solution, and recycling the ethanol to obtain a crude extracting solution; (2) impurity removal: filtering thecrude extracting solution with a ceramic film and then separating the crude extracting solution with macroporous resin columns, carrying out elution by using a 40% ethanol solution and a 60% ethanolsolution successively, collecting 60% ethanol eluant, and recycling ethanol to obtain a crude extract; (3) one-dimensional separation and preparation: carrying out gradient elution on the crude extract obtained from step (2) by using a C18 chromatographic column to obtain four components including Fr.1, Fr.2, Fr.3 and Fr.4; and (4) two-dimensional separation and preparation: separately eluting thefour components obtained from step (3) by using C18 chromatographic columns to obtain the oxytroflavoside A, B, C, D, E, F and G. The method is simple and convenient to operate, the purity of the obtained product is high, and the market application prospect is wide.

The invention relates to a method for preparing chemical reference substances used in chromatographic separation of Oxytropis based on a parallel separation mode. The method comprises the following steps: (1) preparing Oxytropis extract: subjecting Oxytropis to ultrasonic extraction and pressure-reduced concentration so as to obtain the Oxytropis extract; (2) carrying out extraction: subjecting the Oxytropis extract to dissolving and extraction so as to obtain a petroleum ether part, an ethyl acetate part and a water part, respectively; (3) drying the water part to a constant weight so as to obtain dried powder of the water part; and (4) dissolving the dried powder of the water part, then carrying out separation by using a preparative chromatographic device with a parallel separation mode so as to obtain two compounds meeting requirements of chemical reference substances and having purity of more than 98%, i.e., maltol-3-o-beta-D-glucoside and tryptophan. The method provided by the invention has the advantages of simple process, high repeatability and high recovery rate; and the two obtained compounds have good anticancer activity.
