Embodiment 1

[0038] Such as figure 1 As shown, a method for extracting the gradient of Manshanhong comprises the following steps:

[0039] Step S1. Put the mangosteen raw material into the pulverizer 1 for pulverization;

[0040] Step S2. The crushed mangosteen raw material falls into the rotary cutting machine 2 for cutting;

[0041] Step S3. The cut mangosteen raw material falls into the first extraction chamber 3 containing 30% ethanol, the mixture in the first extraction chamber 3 is fully stirred by the stirring device 4, soaked for a certain period of time, and heated after soaking for a certain period of time Leaching, the evaporated ethanol flows directly back to the first extraction chamber 3 after being condensed by the condenser, so soaking and reflux 2-3 times;

[0042] Step S4. After soaking and reflux for 2-3 times, transfer the mixture in the first extraction chamber 3 to the top of the first filter plate 6 through the suction pump 5, and filter through the first filter pl...

Embodiment 2

[0061] Embodiment 2 is a further optimization of Embodiment 1.

[0062] Such as image 3 As shown, the pulverizing device includes a first gear 20, a second gear 21, a third gear 22, a first rotor 23, a second rotor 24 and a device housing 25, and the saw teeth of the first rotor 23 and the second rotor 24 are mutually staggered. , the serrations of the first rotor 23 and the second rotor 24 are all in the shape of a sharp knife, the first rotor 23 and the second rotor 24 are all arranged in the device housing 25, and one end of the first rotor 23 and the second rotor 24 is connected to the device The housing 25 is rotationally connected, the other end of the first rotor 23 is fixedly connected to the second gear 21, the other end of the second rotor 24 is fixedly connected to the third gear 22, the first gear 20 is connected to the first motor 16, and the first gear 20. The second gear 21 and the third gear 22 are sequentially meshed and connected.

[0063] The rotary cutti...

Embodiment 3

[0066] Embodiment three is a further optimization of embodiment two.

[0067] In order to further improve the extraction effect, use 35% concentration ethanol to extract between the steps of using 30% concentration ethanol and 40% concentration ethanol for extraction;

[0068] Between the steps of extraction with 40% ethanol and 50% ethanol, 45% ethanol was used for extraction.

[0069] details as follows:

[0070] Such as Figure 4 As shown, a method for extracting the gradient of Manshanhong comprises the following steps:

[0071] Step S1. Put the mangosteen raw material into the pulverizer 1 for pulverization;

[0072] Step S2. The crushed mangosteen raw material falls into the rotary cutting machine 2 for cutting;

[0073] Step S3. The cut mangosteen raw material falls into the first extraction chamber 3 containing 30% ethanol, the mixture in the first extraction chamber 3 is fully stirred by the stirring device 4, soaked for a certain period of time, and heated after ...

Abstract

The invention provides a rhododendron dauricum gradient extraction method. The rhododendron dauricum gradient extraction method comprises the following steps: S1, crushing a rhododendron dauricum raw material; S2, cutting after crushing; S3, falling into a first extraction cavity containing 30% ethanol, fully stirring and soaking, and then heating and extracting for 2-3 times; S4, filtering and separating out primary filtrate and primary filter residues, and enabling the primary filter residues to fall into a second extraction cavity containing 40% ethanol; S5, fully stirring and soaking, and then heating and extracting for 2-3 times; S6, filtering and separating secondary filtrate and secondary filter residues, and enabling the secondary filter residues to fall into a third extraction cavity containing 50% ethanol; S7, heating and extracting for 2-3 times after fully stirring and soaking; S8, filtering and separating tertiary filtrate and tertiary filter residues, and enabling the tertiary filter residues to fall into a filter residue recovery cavity; and S9, heating the primary filtrate, the secondary filtrate and the tertiary filtrate to distill out ethanol, and thus obtaining a total flavone leaching concentrated solution. The invention further provides a rhododendron dauricum gradient extraction device. The device and method solve the problem that the transfer rate of total flavonoids in a conventional extraction method is low.

Description

technical field [0001] The invention relates to the technical field of medicine extraction, and more specifically relates to a gradient extraction device and method for Mangosteen Radix. Background technique [0002] Folium Rhododendri Daurici is the dry leaf of Rhododendron dauricum L. in the family Rhododendronaceae. It was first published in the "Handbook of Commonly Used Chinese Herbal Medicines in Northeast China", and is now included in the 2020 edition of the "Pharmacopoeia of the People's Republic of China", p361. Manshanhong mainly contains volatile oil and flavonoids, which are the main components for treating cough, asthma and chronic bronchitis. The 7 flavonoids are: isohyperoside, hyperoside, kaempfer-ol, quercetin, myricetin, farrerol, 8 -Demethyl farrerol (8-desmethyl farrerol), the traditional extraction methods of flavonoids mainly include water decoction, soaking, alkali extraction, acid precipitation, ethanol extraction, etc., but the transfer rate of to...
