[Abstract]:Zanthoxylum bungeanum Maxim, a Rutaceae Zanthoxylum plant, is an edible and medicinal plant. Its dried and ripe peel is called Zanthoxyli Pericarpium. It has the effect of stopping pain and killing itching. It is commonly used in traditional Chinese medicine clinic. It is used in the treatment of cold abdominal pain, epigastric pain, vomiting and diarrhea, ascariasis, etc. Zanthoxyli Semen is used to treat eczema and itching. Zanthoxyli Semen has the functions of water permeation, dampness elimination, expectoration and relieving asthma. It is mainly used in the treatment of edema, asthma and other symptoms. China is rich in Zanthoxyli resources and has a huge production. Modern research shows that Zanthoxyli Semen contains a variety of resource chemical components in the fruit, in medicine, food, health care. It is widely used in many fields, such as cosmetics and so on. On the basis of sorting out and analyzing the related literature and systematically reviewing the research status of Zanthoxylum medicinal plant resources in China, the ripe fruit of Zanthoxylum bungeanum in Tianshui area of Gansu province was selected as the research object. Based on the research ideas and methods of Chinese medicine resources chemistry, the resources of Zanthoxylum bungeanum bungeanum bungean Based on the principle of hierarchical utilization, the chemical composition of Zanthoxylum bungeanum was analyzed and evaluated for the purpose of comprehensive utilization and industrialization development of Zanthoxylum bungeanum resources, and the potential resource value and product development were preliminarily explored in order to provide scientific basis for the comprehensive utilization and industrialization development of Zanthoxylum bungeanum resources as well as to raise the capital of Zanthoxylum bungeanum. The analysis and evaluation of the chemical constituents of Zanthoxylum bungeanum fruits were carried out to clarify the composition and distribution characteristics of the resource substances in Zanthoxylum bungeanum fruits and fully release the resource value of Zanthoxylum bungeanum fruits. Phase chromatography-mass spectrometry (UPLC-TQ/MS) and other technical means, pepper mature fruit peel, seeds and seed oil contained in the volatile oils, phenolic acids, flavonoids and other medicinal efficacy-related resource active substances, as well as fatty acids, carbohydrates, proteins and amino acids, nucleosides and alkaloids related to nutrition and health resources The results showed that there were many different types of volatile components in the peel and seeds of Zanthoxylum bungeanum. Terpenoids and their oxygen-containing derivatives were the main components of volatile oils. Linalyl acetate accounted for a relatively high proportion of volatile oils in Zanthoxylum bungeanum fruit. Comparing the different parts of Zanthoxylum bungeanum fruits, it was found that the volatile oils in the peel were more abundant than those in the seed, and the contents of the main components were also relatively high. (2) The analysis of flavonoids and phenolic acids showed that the flavonoids and phenolic acids in Zanthoxylum bungeanum fruits were mainly distributed in the peel. The contents of chlorogenic acid, quercetin-3-O-rutin, hyperoside, quercetin-3-O-glucoside and quercetin were 2.15, 1.99, 3.94, 1.69, 2.04 mg/g, respectively, while the phenolic acids and flavonoids were not detected in Zanthoxylum bungeanum seeds and Zanthoxylum bungeanum seed oils. (3) The study of fatty acid resource chemical constituents was obvious. The results showed that the total fatty acids in peel and seed of Zanthoxylum bungeanum were 108.42 mg/g and 331.63 mg/g, respectively; the total fatty acids in seed oil prepared by pressing Zanthoxylum bungeanum bungeanum seeds were 966.04 mg/g, and the total monounsaturated and polyunsaturated fatty acids accounted for 78.95% of the total fatty acids, especially oleic acid, linoleic acid and linolenic acid, with relatively high contents and their mass fractions respectively. The total contents of soluble polysaccharides in peel and seed of Zanthoxylum bungeanum were 96.33 mg / g and 19.18 mg / g respectively, and the total contents of monosaccharide / oligosaccharides were 9.71 mg / g and 3.78 mg / g respectively. (5) Nucleosides and alkaloids in the peel and seed of Zanthoxylum bungeanum were different in composition and content. The total contents of nucleosides and alkaloids in the peel and seed of Zanthoxylum bungeanum were 2.14mg/g and 3.94mg/g, respectively. Uridine was found in the peel and seed of Zanthoxylum bungeanum bungeanum. The contents of adenosine, inosine and thymidine in peel and seed of Zanthoxylum bungeanum were 0.47 mg/g, 1.22 mg/g, respectively. (6) The analysis of total protein and amino acid resources showed that the total protein content in peel of Zanthoxylum bungeanum (92.32 mg/g) was much higher than that in seed (10.97 mg/g), and the total hydrolyzed amino acid content in peel was about 52.90 M. The content of proline was the highest (9.95 mg/g), the total amount of hydrolyzed amino acids in seeds was about 4.66 mg/g, and the proportion of glutamic acid was the highest (1.03 mg/g). The total content of free amino acids in Pepper pericarp was about 11.02 mg/g, and the content of free amino acids in pepper seed was relatively low (0.57 mg/g). The content of free amino acids in seeds was relatively high. 2. Utilization of Zanthoxylum bungeanum L. fruits was studied. (1) The effects of water extract and seed oil from Zanthoxylum bungeanum L. seeds on asthmatic rats induced by cold and overwork combined with ovalbumin were evaluated. Seed oil could interfere with inflammatory cells, inflammatory factors and lung histopathological injury in model rats to a certain extent, and the asthmatic rats tended to normalize in the water extract treatment group and the seed oil treatment group of Zanthoxylum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bungeanum bun The mechanism of Zanthoxylum bungeanum seed intervention on asthmatic rats with cold-retention lung syndrome was studied. 28 potential biomarkers were identified in serum and urine of model rats compared with normal rats. Among them, linoleic acid metabolism, arachidonic acid metabolism, glyoxylic acid and dicarboxylic acid metabolism were involved in the potential biomarkers identified in serum. Among the metabolic pathways identified in rat urine, glutamine and glutamate metabolism, pentose and glucuronic acid biotransformation, alanine, aspartate and glutamate metabolism, nicotinate and nicotinamide metabolism, sphingolipid metabolism, arginine and glutamate metabolism were involved. Proline metabolic pathways were relatively high. The analysis of the above potential markers in serum and urine of rats treated with water extract and seed oil from Zanthoxylum bungeanum seeds showed that the tested drugs affected linoleic acid metabolism, glycerol phospholipid metabolism, pentose and glucuronide ester biotransformation, nicotinate and nicotinamide metabolism. (3) In vitro antioxidant activity of Zanthoxylum bungeanum seed oil, Zanthoxylum bungeanum peel volatile oil and amide fraction showed strong scavenging ability to DPPH and ABTS, and their IC50 (half inhibitory concentration) were 1.55 mg/ml, 0.23 mg/ml, respectively. The IC50 value was 1.07 mg/ml, the scavenging ability of volatile oil and seed oil to DPPH free radical was weaker than that of amide part, IC50 value was 19.36 mg/ml and 16.38 mg/ml, respectively; the volatile oil of Zanthoxylum bungeanum showed the strongest reducing ability in FRAP test, followed by amide part, and the antioxidant level of the three groups of samples showed a certain dose-effect phase in the linear range of FeSO4.
