Embodiment 1

[0030] Embodiment 1: according to such as figure 1 Shown preparation process, the preparation of Kudingcha total glycosides, comprises the following steps:

[0031] 1. For the picked Kuding tea leaves, use DWIM-20MV8 microwave drying and sterilizing machine within 12 hours to carry out microwave enzyme passivation treatment, set microwave output power: 15KW, transmission speed: 1m / min, and feed the leaves The thickness of 5cm, continuous feeding. The process of microwave enzyme passivation treatment is also a process of sterilizing and drying raw materials.

[0032] 2. Crushing and extraction of Kuding tea leaves

[0033] 1) Kuding tea leaves are pulverized and passed through a 20-mesh sieve to obtain Kuding tea coarse powder;

[0034] 2) Add 50% edible ethanol of 5 times the weight of the coarse powder to the above coarse powder, soak for 1 hour, heat and reflux for 1 hour, filter, add 50% edible ethanol of 5 times the weight of the coarse powder to the dregs, and heat and...

Embodiment 2

[0045] Embodiment 2: the preparation of total glycosides of Kudingcha comprises the following steps:

[0046] 1. For the picked Kuding tea leaves, use the DWIM-20MV8 microwave drying and sterilizing machine within 12 hours to carry out microwave enzyme passivation treatment on the leaves, set the microwave output power: 15KW, and the transmission speed : 3m / min, the thickness of the feeding leaf is 10cm, continuous feeding. The process of microwave enzyme passivation treatment is also a process of sterilizing and drying raw materials.

Embodiment 3

[0060] Embodiment 3: the preparation of total glycosides of Kudingcha comprises the following steps:

[0061] 1. For the picked Kuding tea leaves, use the DWIM-20MV8 microwave drying and sterilizing machine within 12 hours to inactivate the enzyme and passivate the leaves. Set the microwave output power: 15KW, and the transmission speed: 2m / min, the thickness of the feeding leaf is 8cm, continuous feeding. The process of microwave enzyme passivation treatment is also a process of sterilizing and drying raw materials.

[0062] 2. Crushing and extraction of the treated Kuding tea leaves

[0063] 1) Kuding tea leaves are pulverized and passed through a 20-mesh sieve to obtain Kuding tea coarse powder;

[0064] 2) Add 10 times the weight of the coarse powder to the above coarse powder in 80% edible ethanol, soak for 1 hour, heat and reflux for 2 hours, filter, and discard the residue;

[0065] 3) Recover ethanol from the ethanol extract under reduced pressure, and concentrate t...

Abstract

The invention discloses a folium llicis latifoliae total glycoside and a preparation method thereof. The folium llicis latifoliae total glycoside is an extract obtained by carrying out ethanol extraction, water sinking and membrane separating purification on leaves of L.purpurascens Y.C.Yang folium llicis latifoliae or/and L.robustum (Roxb) Blume folium llicis latifoliae as raw materials. The preparation method comprises the following steps of: (1) alcohol extraction: pulverizing the leaves of the L.purpurascens Y.C.Yang folium llicis latifoliae or/and L.robustum (Roxb) Blume folium llicis latifoliae, carrying out heating reflux extraction in ethanol and concentrating extract liquid to obtain an extract; (2) water sinking: dissolving the extract into water for many times to obtain supernatant; and carrying out ultrahigh-speed centrifugal processing on the supernatant to obtain a clear transparent solution; (3) ultrafiltration membrane separating purification: filtering the clear transparent solution by an ultrafiltration membrane and collecting membrane penetrating liquid; and (4) nanofiltration membrane separating purification: carrying out nanofiltration membrane separating purification on the membrane penetrating liquid to obtain purified liquid. The folium llicis latifoliae total glycoside of the invention removes inactive components, retains active components, has auxiliary protecting effect on the chemical liver damage, a sobering function and a fat reducing function, has the advantages of good taste, wider application, simple preparation method and convenient operation and can efficiently extract the active components of the folium llicis latifoliae.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and relates to a plant extract and a preparation method thereof, in particular to a bubuferin and a preparation method thereof. Background technique [0002] Kudingcha is L. robustum (Roxb) Blume or L.purpurascens Y.C.Yang), commonly known as Chading, Fudingcha and Gaolucha. Distributed in Yunnan, Guizhou, Sichuan and other places, Kudingcha is a traditional medicinal plant in my country and has a long history of folk use. Kudingcha has the functions of clearing heat and cooling blood, nourishing liver and kidney, dispelling wind and heat, clearing head, eliminating polydipsia, and removing greasy. effect. However, certain alkaloids in Kudingcha have bitter and cold properties, so not everyone is suitable for drinking Kudingcha. People who suffer from colds, people with cold constitutions, and patients with chronic gastroenteritis should not drink it. Menstrual women and It is also not suit...
