Embodiment 1
[0029] Weigh 500 grams of Pu’er raw tea with an electronic balance, put it into a flask, add 2500ml of medical grade petroleum ether with a boiling point of 30-60°C, soak at 20°C for 10 hours, separate the solid and liquid with a Bush funnel, and collect the clear liquid. The obtained liquid was distilled and concentrated for 2.0 h at a vacuum degree of 0.05 MPa and a distillation temperature of 28° C., and the solvent was removed to obtain 2.4 g of extract.
Embodiment 2
[0031] Weigh 1,000 grams of Pu’er raw tea with an electronic balance, put it into an Erlenmeyer flask, add 10,000ml of petroleum ether with a boiling point of 60-90°C, soak at 30°C for 20 hours, separate the solid and liquid with a Bush funnel, and collect the clear liquid to obtain The liquid was distilled and concentrated for 1.0 h at a vacuum of 0.1 MPa and a distillation temperature of 30° C., and the solvent was removed to obtain 13.50 g of extract.
Embodiment 3
[0033] Weigh 1000 grams of raw Pu-erh tea with an electronic balance, put it into an Erlenmeyer flask, add 15000ml of petroleum ether with a boiling point of 30-60°C, soak at 15°C for 10 hours, separate the solid and liquid with a Bush funnel, and collect the clear liquid to obtain The liquid was distilled and concentrated for 1.5 h at a vacuum of 0.01 MPa and a distillation temperature of 25° C., and the solvent was removed to obtain 13.60 g of extract.
