Embodiment 1

[0044] Take 10kg knotweed raw material as an example, after the raw knotweed cuspidatum is rinsed to remove dust, cut into slices with a thickness of 2mm for use; put the ready-to-use material into the digestion tank, add 200kg enzymatic hydrolysis solution, and adjust the pH value to 0.1mol / L hydrochloric acid solution 4. Carry out enzymatic hydrolysis; the enzymatic hydrolysis solution is a 1% combined enzyme solution, which includes 1 kg distiller's yeast and 1 kg cellulase.

[0045] Extraction: ① Concentration and filtration: After 2 hours of enzymolysis, the raw material after enzymolysis is transferred to an extraction tank, extracted by 3 times the organic solution, and the extract is recovered and concentrated under reduced pressure and filtered; the organic solution is 75% ethanol solution. ②Extraction: Extract the recovered and concentrated liquid with purified water at a ratio of 1:1, repeat 4 times and recover the organic phase to obtain the crude product; ③Refinin...

Embodiment 2

[0047] Add the enzymolysis solution according to the ratio of 1:3 to the mass ratio of the materials to be used, the enzymolysis solution is a 0.6% combined enzyme solution, and the combined enzyme includes 1 part of distiller's yeast, 0.5 part of cellulase, 0.2 part of Lactic acid bacteria. All the other are the same as embodiment 1

Embodiment 3

[0049] Add the enzymolysis solution according to the ratio of 1:2 to the mass ratio of the materials to be used, the enzymolysis solution is a 1.5% combined enzyme solution, and the combined enzyme includes 1 part of distiller's yeast, 0.4 part of cellulase, 0.1 part of Lactic acid bacteria.

Abstract

The invention provides a preparation process of resveratrol, which relates to the field of medicament preparation and solves the problems of low preparation conversion rate, low yield and poor product quality of resveratrol in the prior art. The preparation process of resveratrol comprises the following steps: washing away dust of giant knotweed used as raw material, cutting the giant knotweed into slices or preparing the giant knotweed into coarse powder for later use; adding material to be used to a decomposition pool and adding enzymolysis liquid to carry out enzymolysis; and extracting. Through repeated scientific research improvements, compared with the traditional process, the invention shortens the enzymolysis time by half, improves the enzymolysis quantity by one time and improves the conversion rate by one time. A special enzymolysis process is designed for the preparation process, the operation convenience, the use effectiveness and the conversion reliability greatly exceed that of the traditional process, thereby the quality of finished products is ensured and stabilized more effectively, the cost is reduced by half, and the social benefit is obvious.

Description

technical field [0001] The invention relates to the field of medicine preparation, and relates to a preparation process of resveratrol. Background technique [0002] Resveratrol, also known as Polygonum cuspidatum, English name Resveratrol, molecular formula C 14 h 12 o 3 , molecular weight 228.25 It is extracted and refined from the rhizome of Polygonumcuspidatum Sieb.et Zucc. Odorless, white crystalline powder; hardly soluble in water, easily soluble in ethanol, acetone and other organic solvents. [0003] Resveratrol is a natural antioxidant that can reduce blood viscosity, inhibit platelet aggregation and vasodilation, keep blood flowing, prevent the occurrence and development of cancer, and have anti-atherosclerosis, coronary heart disease, ischemia Sexual heart disease, prevention and treatment of hyperlipidemia. It also has the effects of inhibiting tumors, anti-inflammation, and anti-allergy, and also has estrogen-like effects, which can be used to treat disea...
