[0082]Throughout this specification, unless otherwise mentioned, "%" used to indicate the concentration of a specific substance is solid / solid is (weight / weight)%, solid / liquid is (weight / volume)%, and Liquid / liquid is (volume / volume)%.
preparation example 1
[0084]Preparation Example 1: Preparation of compound crude drug extract (mixed extract)
[0085]The washed and dried yam, dandelion and nepeta were used in the experiment. After mixing the crude yam, dandelion, and nepeta crude drugs in a weight ratio of 1:1:1 to make the total weight 60g, add 10 times the 25% (v / v) ethanol aqueous solution to stir well under normal temperature conditions. Hours and extract. The extract is filtered and concentrated under reduced pressure at a temperature of 50 to 65°C, and then freeze-dried to obtain a powdered composite crude drug extract (mixed extract). The yield is about 12-13%.
preparation example 2
[0086]Preparation Example 2: Preparation of compound crude drug extracts (mixed extracts) of various crude drug mixing ratios
[0087]The washed and dried yam, dandelion and nepeta were used in the experiment. After mixing the crude drugs of the above yam, dandelion, and nepeta in the weight ratio (w / w) described in Table 1 to make the total weight 30g, add 10 times the 25% (v / v) ethanol aqueous solution to the room temperature Stir well under the conditions for 8 hours and extract. After filtering the extract and concentrating under reduced pressure at a temperature of 50-65° C., it was freeze-dried to obtain a total of 7 composite crude drug extract powders. The yields are shown in Table 1.
