Embodiment 1

[0017] Embodiment 1: a kind of method for getting magnolol, comprises the following steps: a. Raw material preparation: one or more in Magnolia officinalis bark, root bark, branch bark, leaf are pulverized; b. Feed intake: pulverized raw material After putting into the extraction kettle, pour in the solvent; c. Extraction: Control the pressure of the extraction kettle to 0.1-2MPa, the temperature to 30-80°C, and the time to 1-3 hours; d. Separation: pump the extracted solvent into the separation kettle for vacuum separation ;

[0018] e. Drying: the separated extract is dried to obtain magnolol.

Embodiment 2

[0019] Embodiment 2: a kind of method for taking magnolol, comprising the following steps: a. Raw material preparation: the dried magnolol bark is crushed into 10-80 mesh; b. Feeding: after the crushed raw materials are put into the extraction kettle, by weight, Raw material: solvent is poured into the solvent at a ratio of 1:1-10. The solvent is one or more of propane, butane, high-purity isobutane (R600a), dimethyl ether (DME), tetrafluoroethane (R134a) and sulfur hexafluoride (SF6). c. Extraction: control the pressure of the extraction kettle to 0.2-1.8MPa, the temperature to 35-70°C, and the time to 1-3 hours; d. Separation: pump the extracted solvent into the separation kettle for vacuum separation;

[0020] e. Drying: the separated extract is dried to obtain magnolol.

Embodiment 3

[0021] Embodiment 3: A method for extracting magnolol, comprising the following steps: a. Raw material preparation: crush fresh Magnolia officinalis root bark and branch bark into 15-60 meshes;

[0022] b. Granulation: Granulation is performed after pulverization. The particle size is 3-4mm. The advantage of granulation is to improve the permeability of the extracted material, increase the extraction efficiency by 50-60%, and at the same time eliminate the adhesion of powdery substances, which is beneficial to the feeding and discharging of the extraction kettle.

[0023] c. Feeding: After the crushed raw materials are put into the extraction kettle, pour propane, butane, high-purity isobutane (R600a), dimethyl ether (DME), tetrafluoroethane (R134a) and sulfur hexafluoride (SF6) One or more solvents, so that the liquid level is 100-150MM higher than the material after submerging the stream; d. Extraction: control the pressure of the extraction kettle to 2MPa, the temperature ...

Abstract

A method for extracting magnolol and its products relate to a method for extracting magnolol, in particular to a method for extracting magnolol with a subcritical method. It includes the following steps: material preparation: crushing one or more of Magnolia officinalis bark, root bark, branch bark, and leaves; feeding: after the crushed raw materials are put into the extraction kettle, pour the solvent; extraction: control the pressure of the extraction kettle to 0.1- 2MPa, temperature 30-80°C, time 1-3 hours; separation: the extracted solvent is pumped into a separation kettle for vacuum separation; drying: the separated extract is dried to obtain magnolol. It can comprehensively utilize bark, root and leaf, which is conducive to sustainable development; the extraction rate is over 85%, and the content of magnolol in the extract is about 65%; it effectively prevents the oxidation and dissipation of heat-sensitive substances; it can maintain medicinal All the ingredients of the plant; the product has been decontaminated, and there is basically no solvent residue; the organic solvent is recycled, which is conducive to environmental protection.

Description

technical field [0001] The invention relates to a method for extracting magnolol. Background technique [0002] Magnolia officinalis is a traditional Chinese medicinal material in my country, and its root bark, bark and leaves all contain magnolol with high medicinal value. Due to the low polarity of this type of compound, although most of it can be extracted by ethanol reflux extraction or osmotic extraction, the yield can reach more than 80%, but in the process of concentration, along with the reduction of alcohol content, it will be recovered from It precipitates out of the solution, adheres to the surface of the wall or forms a rubber-like substance and precipitates at the bottom, reducing the yield. Ethanol reflux extraction, concentration, drying, the average yield of magnolol and honokiol in the dry extract is only 20% to 30%. However, the general extraction method adopts the traditional decoction method plus chemical extraction. The extraction process uses organic ...
