Embodiment 1
[0027] Embodiment 1: the preparation of extract
[0028] Get 1.8kg of glaucous catechu branches and leaves to pulverize, and extract the volatile oil by steam distillation for subsequent use; the dregs are reflux extracted 3 times with 10 times the concentration of 65% ethanol, each time for 0.5 hour, the extract is filtered, the filtrates are combined, and then Add 8 times the amount of petroleum ether-60 for extraction, after layering, take the petroleum ether-60 layer and filter, recover the solvent from the filtrate, concentrate to make an extract with a relative density of 1.30 at 55°C, combine the extract and volatile oil to obtain Glycyrrhiza catechua extract.
Embodiment 2
[0029] Embodiment 2: the preparation of extract
[0030] Take 3.0 kg of G. glabrata branches and leaves and pulverize them, and extract the volatile oil by steam distillation for later use; the dregs are reflux extracted with 6 times the amount of 100% ethanol for 1.5 hours, the extract is filtered, and the filtrate is extracted by adding 6 times the amount of chloroform. After layering, take the chloroform layer and filter it, recover the solvent from the filtrate, concentrate it to make an extract with a relative density of 1.15 at 60°C, combine the extract and volatile oil to obtain the extract of C. glabrata.
Embodiment 3
[0031] Embodiment 3: the preparation of extract
[0032] Get 1.2kg of glaucous catechu branches and leaves, and extract the volatile oil by steam distillation for subsequent use; the dregs are reflux extracted twice with 80% ethanol at a concentration of 8 times, each time for 1 hour, the extract is filtered, and the filtrates are combined, and then Add 7 times the amount of chloroform for extraction, after layering, take the chloroform layer and filter, recover the solvent from the filtrate, concentrate it to make an extract with a relative density of 1.20 at 60°C, combine the extract and volatile oil to obtain the extract of C. .
