Problems solved by technology

This technology extracts with low-carbon alcohol and uses polystyrene macroporous resin for purification to obtain higher content of palm cyanidin and eupholzanthin. However, due to the use of macroporous resin, there may be plastic Chemical residues, and this technology does not carry out the limit of benzopyrene and pesticide residues

Embodiment 1

[0050] A preparation method of mugwort leaf extract includes the following steps:

[0051] (1) First extraction: Take 500 kg of mugwort leaves, crush them, pass through a 24 mesh sieve, add 4000 L of 95% ethanol solution, stir and extract at room temperature for 20 hours, filter with 300 mesh filter cloth to obtain filtrate 1, and filter residue for use;

[0052] (2) Second extraction: add the filter residue to 4000L of 95% ethanol solution, stir and extract at room temperature for 4 hours, filter with 300 mesh filter cloth to obtain filtrate 2;

[0053] (3) Combine the filtrate: combine the filtrate 1 and filtrate 2 to obtain the extract, which is concentrated under reduced pressure at a vacuum of -0.07Mpa and a temperature of 60°C, and concentrated to a relative density of 0.65. The solvent is recovered and filtered through 5 microns. Filter by filter to obtain material liquid 1;

[0054] (4) Adsorption: Add 0.3% activated carbon to feed liquid 1, continue to stir, stand still and s...

Abstract

The invention discloses a preparation method of a folium artemisiae argyi extract. The preparation method comprises the following steps: (1) primarily extracting: crushing and sieving folium artemisiae argyi, adding into an ethanol solution with the concentration of 95%, stirring and extracting at a room temperature, and filtering to obtain a filtrate 1, and a filter residue for use; (2) secondarily extracting: adding the filter residue into the ethanol solution with the concentration of 95%, stirring and extracting at a room temperature, and filtering to obtain a filtrate 2; (3) combining thefiltrates: combining the filtrate 1 and the filtrate 2 to obtain an extract solution, concentrating, recycling a solvent, and filtering to obtain a material liquid 1; (4) adsorbing: adding activatedcarbon into the material liquid 1, continuing stirring, standing for settling, and filtering to obtain a material liquid 2; (5) concentrating: concentrating the material liquid 2 to obtain an extract,namely the folium artemisiae argyi extract. The folium artemisiae argyi extract prepared by the preparation method provided by the invention is high in yield, high in contents of active components eupatilin and jaceosidin, low in content of a carcinogen benzopyrene, low in pesticide residue and high in product safety; the preparation method is simple in technology and easy to operate, and is suitable for industrial production.

Description

Technical field [0001] The invention relates to a plant extract, in particular to a preparation method of a mugwort leaf extract. Background technique [0002] Artemisia argyi, also known as Artemisia argyi, wormwood, and Artemisia halodendron, is the dried leaf of wormwood in the Compositae family. It is a perennial herb. It is a commonly used Chinese herbal medicine. It is warm in nature and bitter in taste. And so on. It is mainly distributed in the Northeast, North, East, Southwest, Shaanxi, Gansu and other places. The flowers are picked before the beginning of summer to remove impurities and dry. Although Artemisia argyi is widely distributed throughout the country and rich in wild resources, its quality is often affected by the place of production. In the Song Dynasty, Ai Ye was bettered by Bei Ai from Tangyin Fudao in Henan and Hai Ai from Ningbo, Zhejiang. Since the Song Dynasty, people generally think that Ai Ye is better from Qichun in Hubei. [0003] As a traditional ...
