| Aconiti kusnezoffii radix.Is one of the most commonly used traditional Chinese medicine and Mongolian medicine.In order to develop the application of Aconitum kusnezoffii radix.in a more comprehensive way,a new method of drying Aconitum kusnezoffii radix.was developed on the basis of a traditional method of processing and fumigation,in order to reduce the toxicity of crude drugs.In order to explore the mechanism of detoxification by raw Aconitum kusnezoffii radix.,baking processed Aconitum kusnezoffii radix.and processed Aconitum kusnezoffii radix were given to Wistar rats by gavage,and the effects of endogenous metabolites and metabolic pathways were studied by metabonomics methods of liver,serum and urine.The effects of Aconitum kusnezoffii radix on pain,rheumatism,inflammation and other symptoms were studied by network pharmacology method " The mechanism of multi-component,multi-target and multi-channel "is an attempt to explain the toxicity of Mongolian medicine kusnezoffii radix and the mechanism of reducing toxicity by baking processed.Objective:1.To select the representative Mongolian medicine Aconitum kusnezoffii radix,which conforms to the Chinese Pharmacopoeia and local standards.2.The toxicity of raw Aconitum kusnezoffii radix.,baking processed Aconitum kusnezoffii radix.and processed Aconitum kusnezoffii radix to various tissues was observed by histopathological sections.3.To collect the liver,urine and serum samples of the rats in raw Aconitum kusnezoffii radix.,baking processed Aconitum kusnezoffii radix and processed Aconitum kusnezoffii radix and blank control groups for non-target metabonomics test,select the different metabolites,determine the possible biomarkers in the baked group,and make the relative content analysis.4.Based on the platform of traditional Chinese medicine network pharmacology analysis,the main active components,targets and related diseases of Aconitum kusnezoffii radix were screened,and the component target disease direct action network was constructed by using the software of Cytoscape.Methods:1.HPLC was used to determine the six main alkaloids of aconitine,hypaconitine,neoaconitine,benzoylaconitine,benzoylhypaconitine and benzoylneoaconitine in the groups of rawAconitum kusnezoffii radix.,baking processed Aconitum kusnezoffii radix.and processed Aconitum kusnezoffii radix;2.40 male Wistar rats were randomly divided into four groups 10,namely:control group,raw group,baked group,processed group.After one week of adaptive feeding and 21 days of administration,the changes of physical signs and the pathological changes of nine tissues including heart,liver,spleen,lung,kidney,spinal cord,brain nerve,sciatic nerve and stomach were observed in each group.3.40 male Wistar rats were randomly divided into four groups,10 rats in each group,i.e.control group,raw group,baked group and processed group.After one week of adaptive feeding and 21 days of drug administration,urine,serum and liver samples were collected from rats in the raw,baked,processed and control groups,and non-target metabonomics was detected by UPLC-QTOF-MS technology,metabonalyst was used to analyze the data after pretreatment by progenesis Qi software.To screen the different metabolites of urine,serum and liver of the model group and the blank control group,which si:multaneously meet the requirements of the multiple of difference(FC)≥1.2 or ≤0.8,Q-value<0.05 and VIP)1.0 under the OPLS-DA mode,through searching the database such as HMDB,thermogram clustering analysis and so on Venn map analysis showed that there were different metabolites in the control group compared with the raw,baked and processed groups,and the related metabolic pathways and relative content changes of the selected different metabolites were analyzed.The urine,serum and urine samples of rats in blank control group,raw group,baked group and baked processed group were analyzed to screen the differential metabolites and target metabolic pathway of processed treatment and other diseases from the differential metabolites of serum and liver;4.The main active components,target points and related diseases ofAconitum kusnezoffii radix.were screened based on the Chinese medicine network pharmacology analysis platform The interaction network of protein and protein was constructed by using the software of Cytoscape and String.The enrichment analysis of Gene Ontology(GO)and action pathway(KEGG)was carried out by using the software of David.Results:1.According to the HPLC method,3.2217mg·g-1,0.4981mg·g-1,0.3271mg·g-1,4.3883mg·g-1 and 0.6046mg · g-1 were determined.They are all in accordance with Chinese Pharmacopoeia and local standards.2.The pathological changes of heart,liver,spleen,lung,kidney,spinal nerve,brain,sciatic nerve and stomach were observed 21 days after administration in control group,raw group,baked group and processed group.no pathological changes were found in brain and sciatic nerve;no pathological changes were found in heart,liver,lung,spleen,stomach and spinal cord except for a few rats in raw group In addition to the control group.3.33 potential metabolic markers(15 in liver,9 in serum and 9 in urine)were screened from liver,serum and urine samples,which may be related to the mechanism of
