Example Embodiment
[0020] Example 1
[0021] A preparation method of honeysuckle extract includes the following steps:
[0022] S1. Raw material processing: Wash the fresh honeysuckle, drain, and chop to get the honeysuckle for use;
[0023] S2. Cold extraction extraction: add the honeysuckle pieces obtained in step S1 to the SPME solid phase extraction device, add 20 times the weight of deionized water, 300W microwave heating, heating temperature not higher than 45℃, keep stirring, rotating speed 500r / min, the volatile gas obtained by extraction is passed into the ice water along the condensed water inlet pipe to be condensed into the extraction bottle, and extracted for 5 hours to obtain the first extract; the substance in the extraction device is filtered, the liquid is the second extract, and the solid Retain
[0024] S3. Water distillation extraction: place the solid obtained in step S2 in a container, heat and distill in a water bath for 2 hours, collect the evaporate, and refine it by molecular...
