Abstract

The invention discloses an extraction method of peat fulvic acid and drug application. A method A is that mixing peat, hyperthermophilic baceria (3-13 CFU), barophilic baceria (5-11 CFU), halophilic baceria (6-12 CFU), basophilic baceria (7 to 13 CFU) and acidophilic bacteria (3-10 CFU) under three conditions including the condition I (10-130 DEG C and 0.05-0.18 MPa), the condition II (5-75 DEG C and 0.05 to 0.12 MPa) and the condition III (5-65 DEG C and 0.05 to 0.12 MPa) and treating for 1-2, 1-3 and 1-2 days respectively; a method B is that mixing the peat and part of the baceria under the conditions I and II for 1-2 and 1-3 days respectively, and mixing with the acidophilic bacteria under the condition III for 1-2 days; a method C is that mixing the peat, the hyperthermophilic baceria and the barophilic baceria under the condition I for 1-3 days, mixing with the halophilic baceria and the basophilic baceria under the condition II for 1-3 days, and mixing with the acidophilic bacteria under the condition III for 1-2 days. Fulvic acid prepared by the method is high in purity.

Description

technical field [0001] The invention relates to a method for extracting and preparing peat fulvic humic acid, a product obtained therefrom, and a medicinal application. Background technique [0002] Peat humic acid belongs to the biopolymers with multi-component, multi-fraction and semi-colloidal properties transformed from the remains of swamp plants (from Biopolymers, [Fen] M. Hofritt [De] A. Steinbicher Editor-in-Chief, Translated by Guo Shengrong, Chemical Industry Press, Modern Biotechnology and Medical Science and Technology Publishing Center, 2004.6 First Edition, Volume 1 Lignin, Humus and Coal). Peat humic acids containing carboxyl, phenolic hydroxyl, quinone and other functional groups can be classified into yellow humic acid, brown humic acid and black humic acid. Fulvic acid has a smaller molecular weight and more active functional groups. [0003] In the 1980s and 1990s, Beijing Haidian Hospital, Tongren Hospital, Heilongjiang University of Traditional Chinese...
