[0019] Example 1.
[0020] 1. The extraction and content determination of the polyphenols of Kobresia japonica are carried out through the following steps.
[0021] 1. Sample preparation and pre-treatment: first use clean sea water to clean the impurities and sand on the surface of the collected fresh sea scorpion, soak in electrolyzed water to desalinate and reduce bacteria, then use 75% alcohol to scald and soak for 3-5S, and drain. . Spread the sea Songzi on a porcelain plate with a thickness of 2cm-4cm, and gently roll it with a roller for 3-5min. The sea Songzi should become wilted without juice. Set a cold air drying box, adjust the temperature to 20-30℃, wind speed 2-5m / s, humidity below 40%, dry with cold air until the moisture content is lower than 12-15%; adjust temperature to 5-10℃, wind speed 2-5m / s , The humidity is below 30%, and the cold air is dried until the moisture content is below 6%. Smash for later use.
