[0045] Example 1: Extraction of perilla essential oil

[0046] Weigh 30g of sieved perilla leaf powder, 300g of 70% ethanol solution (v / v), mixed evenly, placed in a three-necked bottle, set the reaction parameters (see Table 1), extracted in an ultrasonic microwave extractor for a period of time, the extracted mixture was filtered to obtain perilla extract, and the perilla essential oil content in perilla extract was determined by using a UV spectrophotometer to obtain the perilla essential oil content, which was converted to the extraction rate of perilla essential oil (Table 1).

[0050] Example 2: Extraction of honeysuckle flavonoids

[0051] Weigh 30g of sieved honeysuckle powder, 300g of 70% ethanol solution (v / v), mixed evenly, placed in a three-necked bottle, set the reaction parameters (see Table 2), extracted in an ultrasonic microwave extractor for a period of time, the extracted mixture was filtered to obtain honeysuckle extract, and the honeysuckle flavonoid content in honeysuckle extract was determined by ultraviolet spectrophotometer, and the extraction rate of honeysuckle flavonoids was obtained (Table 2).

[0054] Example 3: Extraction of eucalyptus leaf polyphenols

[0055] Weigh 30g of eucalyptus leaf powder after sieve, 300g of 70% ethanol solution (v / v), mixed evenly, placed in a three-necked bottle, set the reaction parameters (see Table 3), extracted in an ultrasonic microwave extractor for a period of time, filtered the extracted mixture to obtain eucalyptus leaf extract, and used ultraviolet spectrophotometer to determine the polyphenol content of eucalyptus leaf leaves in eucalyptus leaf extract, converting to the extraction rate of eucalyptus leaf polyphenols (Table 3).
