The invention relates to preparation of 
clathrate compound containing isoflavone and 
cyclodextrin of chickpea, comprising the following steps: 
grinding the chickpea into 
powder, 
drying, adding 
petroleum ether, backflowing for 1.5 hours in water bath with the temperature of 70 DEG C, filtering and 
drying; adding 65% 
alcohol, putting the obtained mixture in water bath with the temperature of 85 DEG C, backflowing for 1.5 hours, carrying out backflowing for two times, and filtering; adding 
distilled water, pouring the 
distilled water into a macroporous absorbing column, adjusting the flow rate to be 1ml / min, using a 
beaker to receive samples passing the column; adding 70% 
alcohol, adjusting the flow rate to be 0.5ml / min, collecting flow liquid, and distilling to obtain pure flavone; charging 
cyclodextrin and pure isoflavone with the 
mass ratio of 4-6:1, adding 2-4 times of water under normal temperature, 
grinding the mixture to be pasty, vacuum-
drying, cleaning with 
alcohol, and drying to obtain the 
clathrate compound. The preparation has simple method, low cost, little 
toxicity of selected microcapsule wall materials, can increase the 
solubility of 
botanical drug after clathrate, improve the 
bioavailability of isoflavone and has good application prospect.
