Embodiment 1
[0117] (1) Raw drug: toad venom 2g.
[0118] (2) Take toad venom, crush it through a 20-mesh sieve, add 80% ethanol to reflux for extraction for 3 hours, recover ethanol from the reflux liquid under reduced pressure, concentrate it, and dry it in vacuum to obtain the extract of toad venom.
[0119] (3) The toad venom extract is clathrated with HP-β-CD using a saturated aqueous solution method: HP-β-CD is added with water at a ratio of 20ml / g-30ml / g, heated to dissolve, cooled to room temperature, according to the toad venom extract: The ratio of HP-β-CD=1:10 (v / g) was added to the toad venom extract, stirred for 2 hours, taken out and refrigerated for 20 hours, suction filtered, and the filter residue was dried at room temperature for 36 hours to obtain 10 g of inclusion complex of toad venom extract.
