Embodiment 1

[0068] Get 50kg of kapok leaves, use 60% ethanol 12 times of the weight of the material, and heat reflux to extract three times, each time for 2 hours. After the extract was concentrated, it was allowed to stand overnight and filtered, and the residue was 5.4 kg of total phenolic extract of kapok leaves.

Embodiment 2

[0070] Take 50 kg of kapok leaves, extract with 70% ethanol which is 15 times the weight of the material, and extract under reflux three times, each time for 1 hour. After the extract is concentrated, put it on the AB-8 macroporous resin column, first use 4 times the amount of water to elute to remove impurities, then use 7 times the amount of 30% ethanol to elute, collect the eluate, and concentrate to obtain the total phenolic extract of kapok leaf 4.7 kg.

Embodiment 3

[0072] Take 400 mg of the extract prepared by the method in Example 2 and 200 mg of micropowder silica gel, pass through a 60-mesh sieve and mix thoroughly, add an appropriate amount of magnesium stearate to mix, and dry granulate. Pass through a 40-mesh sieve and fill into capsules.
