AI Technical Summary
In the existing technology, the extraction methods of active ingredients from Phyllanthus emblica have failed to effectively inhibit the activity of coronavirus main protease, transmembrane serine protease 2 and neuraminidase, which limits its application in the treatment of related diseases.
Using solvent extraction combined with membrane filtration technology, an extract of Phyllanthus emblica with a molecular weight of less than 1000D was prepared. High-purity Phyllanthus emblica extract was obtained through multi-stage membrane filtration and concentration, which was used to inhibit the activity of coronavirus main protease, transmembrane serine protease 2 and neuraminidase.
The prepared Phyllanthus emblica extract was significantly superior to that prepared by traditional methods, exhibiting stronger inhibitory effects on coronavirus main protease, transmembrane serine protease 2, and neuraminidase. It also showed good water solubility and significantly enhanced pharmacological activity, surpassing Corilagin reference standard.
