Preparation method of rhizoma belamcandae isoflavone aglycone

The invention relates to the technical field of preparation of traditional Chinese medicine, and particularly discloses a preparation method of rhizoma belamcandae isoflavone aglycone. The preparationmethod of the rhizoma belamcandae isoflavone aglycone includes dealcoholizing alcohol extract of fibrous roots of rhizoma belamcandae, adding fermentation liquid of inonotus hispidus, conducting enzymolysis to remove enzymes and thallus impurities in an enzymatic hydrolysate, and performing resin adsorption and purification to obtain the rhizoma belamcandae isoflavone aglycone. The preparation method has the advantages that preparation conditions are mild, the method is simple, the cost is low, and the purity and yield of the rhizoma belamcandae isoflavone aglycone extracted and prepared fromthe fibrous roots of the rhizoma belamcandae are greatly increased. 本发明涉及中药制备技术领域，具体公开一种射干异黄酮苷元的制备方法。所述射干异黄酮苷元的制备方法，是将射干须根的醇提液去醇处理后加入粗毛纤孔菌的发酵液中进行酶解，去除酶解液中的酶和菌体杂质，进行树脂吸附纯化，得到射干异黄酮苷元。本发明制备条件温和，方法简单，成本低，大大提高了从射干须根中提取和制备的射干异黄酮苷元的
