Problems solved by technology

There are two main links in the current production process of Ficus microphylla water extract extract, one is to use a large amount of ethanol to precipitate macromolecular impurities, and the other is to concentrate the extract at least twice, which consumes a lot of heat energy

Embodiment 1

[0029] The preparation of embodiment 1 Ficus microphylla water extract extract

[0030] The technological process of inductive preparation is roughly as follows:

[0031] Small-leaf ficus leaf (shade-dried or air-dried) → water extraction → primary filtration and microfiltration treatment of water extract → ultra-frequency vibration filtration and sieving → ultra-frequency vibration membrane filtration dehydration → concentrated liquid drying → crushing and packaging → finished extract.

[0032] In the specific operation, as shown in Figure 1, follow the steps below:

[0033] (1) the fig leaves are dried or air-dried;

[0034] (2) Water extraction, according to the weight ratio of Ficus lobata leaf and water is 1: 8~10, add water and soak for 8~12h, boil and extract;

[0035] (3) Use a 60-200-mesh filter to perform primary filtration and microfiltration of the water extract to remove impurities such as fine sediment, dust, broken diameter leaves, and damaged cell tissues;

Embodiment 2

[0039] Example 2 Ultra-frequency vibration filtering test test results

[0040] (1) at 0.5~5kg / cm 2 Under the high pressure, 10-50HZ vibration frequency, and 1-12mm amplitude, the liquid medicine is circulated and filtered in the overfrequency vibration filtration system, and the machine stops after the filtration is completed. Samples were taken, and the permeability of small molecular substances was measured by gel chromatography, and the measurement results were consistent with the results of (4) gravimetric method in Example 2.

[0041] (2) Check flux

[0042] Start the over-frequency vibrating membrane filtration system, wait for about 5 to 10 minutes after the mechanical stability, and start to inspect the flux regularly. Each membrane is inspected continuously for 3 days under the same conditions.

[0043] For the single-layer membrane in the test area, the flux of type A membrane with pore size of 300,000 Daltons stabilized at 65% after 3 hours, the flux of type B me...

Abstract

The invention discloses the preparation method of an extract of India laurel fig leaf liquid, including the steps of airing or air-drying the India laurel fig, aqueous extracting, primary filtering and micro filtering the aqueous extracted liquid, ultrafiltrating and nano-filtrating by a superfrequency vibrating membrane, filtering and condensing by a superfrequency vibrating and dehydrating membrane, drying, crushing and packing. The technology of using the superfrequency vibrating membrane to filtering replaces the traditional alcohol precipitating by aqueous extraction and condensing by heating, and the invention is capable of improving the product quality, saving the energy and reducing the discharge and belongs to the method of saving the energy, reducing the discharge and being green and environmental protective. At the same time, the invention has important meaning for developing and improving the technology of traditional Chinese medicine extraction and separation.

Description

technical field [0001] The invention relates to a pharmaceutical technology, in particular to a preparation method of water extract of ficus microphylla leaf extract. Background technique [0002] The ingredients of traditional Chinese medicine are complex. When extracting and separating, the active ingredients should be retained and macromolecular impurities such as tannins, proteins, starches, and resins should be removed as much as possible. Traditional Chinese medicine extraction methods such as distillation and alcohol precipitation are not easy to remove impurities, the loss of active ingredients is large, and a large amount of organic solvents that pollute the environment are consumed, especially the ethanol used to separate and precipitate impurities. [0003] Membrane filtration is a new energy-saving and emission-reducing technology for separating particles and large and small molecules in liquids. In most traditional Chinese medicine extraction processes in the f...
