Description

Technical Field

[0001] The utility model belongs to the technical field of alkali washing equipment and relates to an alkali washing device for plant extracts. Background Art

[0002] Birch (Betula platyphylla Suk.) is a cold-resistant deciduous tree belonging to the genus Betula Linn. of the family Betulaceae. Its bark has complex components and diverse pharmacological activities. As early as in Li Shizhen's Compendium of Materia Medica, it was recorded that birch bark can be used to treat yellow marks, epidemics, mastitis, cough and acute and chronic dysentery. In recent years, studies have shown that birch bark extract birch triterpenoids have important antibacterial, antiviral, choleretic and liver-protective effects, antimalarial, anti-inflammatory and anti-tumor activities, especially in anti-HIV activity and anti-cytotoxicity of various tumor cell lines. It is highly effective and low in toxicity and is considered to be the most promising drug lead compound. The anti-inflammatory properties of the main components of birch bark triterpenoids, betulin and betulic acid, have been verified in in vitro and in vivo model systems, mainly achieved by inhibiting non-neural gene pathways, and may also be due to the interaction between betulic acid and glucocorticoid receptors. Betulin can inhibit the expression of NF-κB and inflammation-related genes in the inflammatory pathway of AC16 cardiomyocytes, thereby protecting cardiomyocytes, having a good therapeutic effect on alcoholic liver damage, and can relieve physical fatigue and improve hypoxia tolerance; at the same time, betulin can promote cell proliferation and repair wrinkles by increasing Col synthesis and the expression of related proteases. Other studies have shown that betulin has anti-depressant and anti-anxiety effects and has good immunomodulatory effects. During the extraction process of betulin, the preliminary extract needs to be alkaline washed to remove impurities. However, most of the existing alkaline washing devices use static washing to avoid splashing of alkali during the washing process, but this results in poor cleaning effect and is inconvenient to clean up the impurities remaining after cleaning.
