According to records in compendium of materia medica, lily has the efficacies of tonifying heart and lung, reinforcing kidney, nourishing brain, clearing heart fire, soothing nerves, moistening lung dryness, conditioning spleen and stomach, tonifying qi, regulating middle warmer, clearing heat, relieving cough, nourishing yin, stopping bleeding, relieving summer heat and the like. Bulbus Lilii mainly contains steroid saponin, alkaloids, phenolic acid glyceride, phospholipid, polysaccharide, amino acids and flavonoids. Wherein, the steroid saponin compound is the main active component, and has biological activities of anti-depression, antioxidation, anti-inflammation, anticancer, and the like. In order to reveal the material basis of treating diseases by traditional Chinese medicines taking saponin compounds as main active ingredients and fully utilize the pharmacological activity of lily steroid saponin monomer compounds, lily saponin monomers need to be separated and purified, but the existence of a large number of saponin compounds with similar structures in lily makes the separation of the steroid saponin monomer compounds very difficult, and the saponin compounds are generally absorbed only at the ultraviolet tail end, which brings difficulty to the on-line detection of the saponin compounds by utilizing high performance liquid chromatography, so how to realize the separation and purification of the saponin monomers in lily is a problem which troubles research and development personnel.
Disclosure of Invention

adding the dry extract into a gel chromatographic column filled with Sephadex LH-20, eluting with a methanol solution or an ethanol solution with the volume concentration of 49-53%, detecting and monitoring by high performance liquid chromatography, counting the next part with the ultraviolet absorption peak value of a main peak as a sectional basis and the ultraviolet absorption value lower than 5 milliamperes to obtain 5 components, and recording the components as a component 1, a component 2, a component 3, a component 4 and a component 5 according to the collection time sequence;
and step three, respectively purifying the component 3, the component 4 and the component 5 to obtain 3 corresponding monomer compounds.
Compared with the prior art, the invention has the following beneficial effects:
besides saponins, lily contains very complex components such as saccharides, flavonoids, alkaloids, trace elements and the like, so that the separation of lily saponins from other substances is difficult to realize, the content of saponins in lily is very low, the structure and the physicochemical properties are very similar, and a plurality of monomers of lily saponins are difficult to obtain by a simple separation method at one time. According to the method for separating and purifying the lily saponin monomer, provided by the invention, aiming at the physicochemical properties of each component in lily, a large amount of impurities in lily are effectively removed through the sequential collocation of the steps I to III and the combination of proper parameters, so that the lily saponin monomer with higher purity is obtained. The method for separating and purifying the lily saponin monomer can realize the target preparation of the lily saponin, can obtain a plurality of lily saponins with known activity at one time, and simultaneously enrich and separate trace saponins, thereby continuously enriching saponin libraries and providing a material basis for activity research of saponin compounds and development of new drugs with single components.
Preferably, in the first step, the extract of lily bulb leaves is prepared by the following method: crushing lily bulb leaves, adding an ethanol solution with the volume concentration of 65-70% and the volume which is 4-5 times that of the lily bulb leaves, heating, refluxing and extracting for 2-3 times, concentrating under reduced pressure, and drying to obtain an extract of the lily bulb leaves.
