Embodiment
[0090] Throughout this specification, unless otherwise mentioned, "%" used to express the concentration of a specific substance is solid / solid (weight / weight)%, solid / liquid (weight / volume)% and Liquid / liquid is (vol / vol) %.
preparation example 1
[0092] Preparation Example 1: Preparation of 4 kinds of compound crude drug extracts (mixed extracts)
[0093] The washed and dried mustard seeds, sand ginseng, honeysuckle and perilla seeds were used in the experiment. After mixing the crude drugs of the above-mentioned mustard seed, sand ginseng, honeysuckle, and perilla seed in a weight ratio of 1:1:1:1 to make the total weight 60 g, add 10 times 25% (v / v) ethanol aqueous solution to Stir well for 72 hours at room temperature and extract. The extract was filtered, concentrated under reduced pressure at a temperature of 50 to 65° C., and then freeze-dried to obtain a complex crude drug extract (mixed extract) in a powder state. The yield is 12-13%.
preparation example 2
[0094] Preparation Example 2: Preparation of 3 kinds of compound crude drug extracts (mixed extracts)
[0095] Washed and dried mustard seeds, sand ginseng and honeysuckle were used in the experiment. After mixing the crude drugs of mustard seed, sand ginseng, and honeysuckle in a weight ratio of 1:1:1 to make the total weight 60 g, add 10 times the 25% (v / v) ethanol aqueous solution to make it well under normal temperature conditions. Stir for 72 hours and extract. The extract was filtered, concentrated under reduced pressure at a temperature of 50 to 65° C., and then freeze-dried to obtain a complex crude drug extract (mixed extract) in a powder state. The yield is about 12-14%.
