The invention relates to an erianin product and aims at providing a product produced from the inclusion to erianin by using hydroxypropyl-Beta-cyclodextrin and series derived products of an erianin inclusion compound. The erianin inclusion compound comprises active ingredients of erianin and an inclusion agent which is hydroxypropyl-Beta-cyclodextrin and the weight ratio of the erianin to the inclusion agent is 1:8-1:11. As the active ingredients of the erianin are externally wrapped with hydroxypropyl-Beta-cyclodextrin groups which have the characteristic of water solubility, the applicationmethods of the erianin which is slightly water-soluble originally are greatly expanded. The included erianin can be prepared into tablets, capsules, oral solution, granules, injecta, and the like, canbe conveniently utilized in various ways and is also easy to be absorbed by human bodies.
