Embodiment 1
[0020] 1. Take 10 parts by weight of Flos Lonicerae and 10 parts by weight of Forsythia, add 8 times their total weight in water, soak for 3 hours, and steam distill for 6 hours to extract volatile oil; filter and retain medicinal residues, and discard the filtrate.
[0021] 2. Dissolve the extracted volatile oil with an equal volume of absolute ethanol and add it dropwise into the β-cyclodextrin solution. The volume of the β-cyclodextrin solution in ml: the weight of the β-cyclodextrin in g is 10:1. The volume of volatile oil in ml: the weight of β-cyclodextrin in g is 1:4, stir at 40-60°C for 2 hours, refrigerate at 4°C for 24 hours, filter with suction, and dry the precipitate at 40°C to obtain volatile oil clathrate .
[0022] 3. Take 5 parts by weight of Scutellaria baicalensis and the dregs of step 1, then add 6 times its weight in ethanol aqueous solution, the volume concentration is 70% (v / v), and reflux (80°C) to extract 3 times, each time 1 hours, filter, keep the m...
