Lipopolysaccharide (L PS) is derived from an outer membrane of gram-negative bacteria, can stimulate macrophage cells in vivo to synthesize and release various inflammation mediators, and is the most common inflammation factor, so high-concentration bacterial endotoxin L PS is commonly used for inducing an acute hepatitis model, an organism is stimulated by an inflammation factor after being injected into an abdominal cavity with high concentration of L PS to activate neutrophil, eosinophil and mononuclear-phagocyte systems in vivo, so that release of various inflammation mediator prostaglandins (PGE2), tumor necrosis factor- α (TNF- α), interleukin-1L (I L1- β), interleukin-6 (I L-6), interferon-gamma (IFN-gamma) and the like is caused, permeability of a blood vessel is increased, inflammation cell chemotaxis is caused, so that generation of acute inflammation is induced [12, PGE2 is eicosyl unsaturated fatty acid, which is one of prostaglandin, which is used as an important inflammation mediator, blood vessel, blood flow and the like, when organism is stimulated by peripheral cells, the extracellular factors of peripheral cells, the Escherichia coli is stimulated by a macroreticular total paeonol, total paeonol synthesis and total paeonol synthesis of macrophage cell synthesis, total paeonol synthesis and total paeonol synthesis, the total paeonol release of the cholesterol, the total paeonol is not only a macroreticular cholesterol, but also can be used as a major inflammatory reaction of a macroreticular cholesterol, the total cholesterol of a macrogol, the total cholesterol of a macrogol in an endothelial cell, the total cholesterol of a macrogol of a total cholesterol of a macrogoldthread out, the total cholesterol of a total cholesterol of.

According to the traditional Chinese medicine, the syndrome of heat-toxin and blood stasis is that body fluid and blood are burned by warm diseases, blood is clotted and stagnated after being smoked, the primary factor is that warm heat-toxin enters nutrient-blood during the formation process, nutrient-yin depletion and collateral damage and body fluid damage are pathological, and the development trend is that heat-toxin is exuberant, heat-stasis is mixed and body resistance is weakened. Researches find that the toxic heat and blood stasis syndrome has close relationship with inflammation, fever and blood stasis of modern medicine in the aspects of pathology, pathogenesis and treatment, and a plurality of inflammatory diseases and complications thereof have the toxic heat and blood stasis syndrome manifestations clinically, such as rheumatic fever, viral hepatitis, allergic purpura, systemic lupus erythematosus and the like. The traditional Chinese medicine theory enables endotoxin to belong to heat evil and toxin evil, and the endotoxin is used for preparing the heat-toxin blood stasis syndrome animal model, so that the evolution process of diseases related to invasion of exogenous evil, heat entering nutrient blood, excessive heat being toxin and blood refining blood stasis in traditional Chinese medicine can be well simulated, the theory of formation of heat-toxin blood stasis syndrome in traditional Chinese medicine is met, and the change of objective biomedical indexes such as blood rheology, inflammatory factors and the like is provided for the heat-toxin blood stasis syndrome. Carrageenan is commonly used for causing animal inflammation models, and can be used in combination with endotoxin for preparing models with toxic heat and blood stasis syndrome.

After the body is injected with endotoxin and carrageenan, inflammatory cell factors such as I L-1 β, TNF- β, IFN-gamma, I L-6 and the like can be generated and released by activating a neutrophil, eosinophil and mononuclear phagocyte system in blood, on one hand, the cell factors can be used as endogenous pyrogens to transmit fever signals to a body temperature regulation center through various ways such as blood brain barrier specific transporter transport, endplate organelle and vagus nerve, on the other hand, the increase of the content of peripheral cell factors can induce the expression of prostaglandin synthase (mPGES-1) and cyclooxygenase (COX-2), further promote the synthesis of central fever positive regulation medium PGE2 and cAMP to increase the body temperature, and experimental results show that the PGE2, the cAMP, the I L-1 β, the TNF- α, the IFN-gamma and the I L-6 values are obviously reduced, the PGE L, the I L-6851, the I- α and the total phenols of the red peony root aqueous extract are reduced to further achieve the effect of reducing the release of the inflammatory cell factors and the total paeony phenol, but the total pyrogens the total phenols are better than the release of the fever signals and the inflammatory cell factors.

In addition, inflammatory cytokines such as I L-1 β, TNF- α and the like released by an organism can induce the expression of tissue factors and start an extrinsic coagulation path, vascular endothelial cells are damaged, and exposure of subendothelial collagen starts an intrinsic coagulation path, four coagulation items can reflect the anticoagulation and procoagulant capacity of the organism, and experimental results show that red paeony root water extract and red paeony root total monoterpene can obviously prolong TT, PT and APTT time and reduce FIB content, which indicates that the red paeony root water extract and the red paeony root total monoterpene can improve the blood stasis state of rats by activating corresponding coagulation factors, while red paeony root total phenols have NO obvious effect, NO, ET-1, TXB2 and 6-keto-PGF1 α are active substances closely related to vascular endothelial cell damage and platelet activation, ET-1 has a strong vasoconstriction effect, NO can dilate blood vessels and improve microcirculation, TXB2 can constrict blood vessels and promote platelet aggregation, and 6-keto-PGF1 α can dilate blood vessels and inhibit platelet aggregation, and the balanced disruption of the two can also cause the formation of thrombus.

The preparation of the total paeony glycoside mostly adopts a macroporous resin technology, and the total paeony glycoside prepared by the technology contains components with higher polarity of total phenols of the red paeony root according to the separation principle. The invention adopts a method of combining polyamide resin and macroporous resin, firstly, red paeony root total phenol is separated by a polyamide resin column, then, red paeony root total monoterpene is separated by a macroporous resin column, the red paeony root total phenol is separated from the red paeony root total monoterpene for the first time, and the prepared red paeony root total phenol and the prepared red paeony root total monoterpene are analyzed by fingerprint spectrums, and the chromatographic peaks of catechin and gallic acid in the red paeony root total phenol are found to be the main peaks; the paeoniflorin chromatographic peak is taken as the main component in the total monoterpene of red paeony root, which indicates that the chemical components of the total phenol of red paeony root and the total monoterpene of red paeony root are not crossed with each other. The red peony root total monoterpene and red peony root total phenol are used as important chemical components of red peony root, and animal experiments show that the two can play the roles of anti-inflammation and heat-clearing by reducing the generation and release of inflammatory factors and central fever positive regulation media, thereby achieving the effects of clearing heat and cooling blood; radix Paeoniae Rubra Total phenols and radix Paeoniae Rubra Total monoterpenesImproving the state of blood stasis by maintaining NO and ET-1 balance; however, radix Paeoniae Rubra total monoterpene can also maintain TXB by activating corresponding coagulation factors2Compared with the two, the effect of the total paeony phenol on inflammatory media such as central fever positive regulation media PGE2, I L-1 β, TNF- α and the like is superior to that of the total paeony monoterpene on the heat clearing and blood cooling effects, and the effect of the total paeony terpene on related indexes of blood vessel endothelial cell function and platelet activation such as four blood coagulation items TT, PT, APTT, FIB, ET-1, 6-keto-PGF1 α, TXB2/6-keto-PGF1 α and the like is superior to that of the total paeony phenol on the blood stasis dispelling effects.
