Embodiment 1
[0024] A kind of Tribulus terrestris extract is prepared by following method:
[0025] Take 100kg of Tribulus terrestris, add 500kg of water, soak for 30 minutes, heat and boil for 120 minutes, pour out the decoction, decoct the dregs once more, add 1000kg of water each time, boil for 60 minutes, combine the two decoctions, and filter to obtain the filtrate; Concentrate under reduced pressure to a density of 1.05 g / ml, freeze-dry to obtain component A;
[0026] Filter the obtained filter residue and dry it at 80°C, then add glacial acetic acid so that the ratio of solid to liquid is 1:5g / mL, dip and extract 3 times under the ultrasonic power of 250W, each time for 40min, the extraction temperature is 90°C; filter to obtain the filtrate, the obtained The filtrate was evaporated under reduced pressure at a vacuum of 0.1 MPa and a temperature of 80° C. to remove glacial acetic acid to obtain component B, and component A was mixed with component B to obtain the Tribulus terrestris...
Embodiment 2
[0029] An extract of Tribulus terrestris, prepared by the following method: Take 100kg of Tribulus terrestris medicinal material, add 1000kg of water, heat and boil for 120 minutes, pour out the decoction, decoct the dregs for 3 times, add 500kg of water each time, boil for 60 minutes, combine 4 times The decoction was filtered to obtain the filtrate; the obtained filtrate was concentrated under reduced pressure to a density of 1.20 g / ml, and freeze-dried to obtain component A;
[0030] Filter the obtained filter residue and dry it at 50°C, then add glacial acetic acid so that the ratio of solid to liquid is 1:20g / mL, dip and extract twice at an ultrasonic power of 300W, each time for 20min, and the temperature is 60°C; The vacuum degree is 0.08MPa, the temperature is 70°C, and the glacial acetic acid is evaporated under reduced pressure to obtain component B, and the component A and component B are mixed to obtain the Tribulus terrestris extract.
[0031] The yield of Tribulu...
Embodiment 3
[0033] A kind of Tribulus terrestris extract is prepared by following method:
[0034] Take 100kg of Tribulus terrestris, add 750kg of water, soak for 20 minutes, heat and boil for 100 minutes, pour out the decoction, decoct the dregs for 2 times, add 750kg of water each time, boil for 60 minutes, combine the decoction for 3 times, and filter to obtain the filtrate; Concentrate under reduced pressure to a density of 1.10 g / ml, freeze-dry to obtain component A;
[0035] Filter the obtained filter residue to dry in the air, then add glacial acetic acid so that the ratio of solid to liquid is 1:10g / mL, impregnate and extract twice under the ultrasonic power of 280W, each time for 30min, and the temperature is 75°C; MPa, glacial acetic acid was evaporated under reduced pressure at a temperature of 75°C to obtain component B, and component A was mixed with component B to obtain the Tribulus terrestris extract. .
[0036] The yield of Tribulus terrestris extract is 6.73%, wherein,...
