Embodiment 1
[0022] Preparation of Coptis chinensis extract: Take Coptis chinensis powder and pass it through a 20-mesh sieve to obtain coarse powder, heat and reflux extract the crude fraction with 8 times the amount of 80% ethanol at 90°C for 2 times, each time for 1.5h, combine the filtrates and concentrate, put Dry in a drying oven to a constant weight state to obtain the Coptidis Rhizome extract;
[0023] Take 15g of Coptidis Rhizoma extract and dissolve in 250ml of 50% ethanol, then add 10ml of eucalyptus oil, 3ml of azone, 90ml of propylene glycol successively, add distilled water to make the volume to 500ml, and mix well to obtain a solution of Coptis chinensis extract. After testing, the properties of this solution are brown, transparent and slightly viscous liquid, and the pH and microbial limit are all qualified.
