Example Embodiment

[0015] Example 1:

[0016] (1) After picking the young blueberry leaves, wash them, and then dry them naturally for 12 hours.

[0017] (2) Heating under the condition of vacuum degree of -200KPa, adding 55% ethanol for edible ethanol, with a material-to-liquid ratio of 1:40, and extracting for 70 minutes.

[0018] (3) After the completion of the extraction liquid, the ethanol is recovered by rotary evaporation, and then the extracted blueberry leaves are dried in a drying box at 95°C for 75 minutes, and then simply tapped.

[0019] (4) Grind the blueberry and green fruit under nitrogen, mix with the aforementioned extract, pre-frozen in a freezer at a low temperature of -35°C, then put it into a cold trap pre-cooled drying bin, start the vacuum machine to pump to 80Pa, heat and keep at 15℃, dehydrate for 5h, and then finely grind through 160 mesh sieve after drying.

[0020] (5) Dry blueberry leaves and blueberry fruit powder are mixed in a ratio of 100:10.
