Embodiment 1

[0015] Embodiment 1, method steps are as follows:

[0016] 1. Picking seabuckthorn leaves: Pick young seabuckthorn leaves as much as possible.

[0017] 2. Greening: Picked young seabuckthorn leaves should be greened in time to ensure the maximum content of biologically active substances. When finishing, the temperature should be high,

[0018] short time. The temperature is 160°C, and the time is 15 seconds.

[0019] 3. Kneading: Press and knead gradually, and the shape of the tea sticks is not required, and knead thoroughly and evenly. Kneading time is about 10-15 minutes,

[0020] The purpose is to increase tissue permeability and ensure maximum leaching rate.

[0021] 4. Stir-fry: Stir-fry is divided into two types: two green (110°C, 10 seconds per layer, 60 seconds during the whole process) and bottle fry (not higher than 90°C).

[0022] steps.

[0023] 5. Soaking: Soak in boiling water for 2 hours to increase the extraction rate.

[0024] 6. Extraction: sing...

Embodiment 3

[0030] 11. Packaging Example 2, the method steps are the same as in Example 1, wherein the extraction step adopts ultrasonic extraction, the tea water ratio is 1:10, the temperature is 80°C, the pH is 7-10, and the time is 45 minutes. The extraction rate is 25%. Embodiment 3, the method steps are the same as in Embodiment 1, wherein the drying adopts spray drying, and the extraction rate is 22%. The aromatization step is incorporated into the formulation or shaping process.
