Depth analysis and trend prediction of Glycyrrhiza uralensis

1 Analysis of the basic situation of Glycyrrhiza 1 The effect of Glycyrrhiza is sweet and mild, and it can return to the heart, lungs and spleen It has the functions of invigorating the spleen and Qi, clearing away heat and detoxification, eliminating phlegm and cough, slowing down and relieving pain, and harmonizing various drugs It can be used for spleen and stomach weakness, lassitude and weakness, and can relieve the toxicity of drugs Licorice should not be used with kansui and seaweed 2 The distribution of Glycyrrhiza is mainly in Inner Mongolia, Xinjiang, Ningxia and Gansu Licorice is mainly produced in front of etoke, hangmian, Datla, Aohan, alashanyou, Weng ZHONGTE, etoke, Naiman, alashanzuo, Kailu, zarut and Wushen in Inner Mongolia; Yanchi, Lingwu, Tongxin, Zhongning, Pingluo and Haiyuan in Ningxia; Bachu, Shaya, Awati, Wensu, Kuche, lunming, Weili, shanggaidi, Hejing, Shache, Hetian, Yutian Atushi, Chabuchar, Gongliu, Xinyuan, Fuhai, Buerjin, Shawan, Wusu, Jinghe, Hami, kumeng; Xuanhua, Hebei; Wutai, Shanxi; Chaoyang, Jianping, Anxi, Dunhuang, Huanxian, Minqin, etc The quality of licorice produced in Inner Mongolia and Ningxia is excellent 3 The main components include triterpenoids and flavonoids, in addition to coumarins, amino acids, alkaloids, sex hormones, organic acids, etc Triterpenoids mainly contain glycyrrhizin (mainly potassium and calcium salts of glycyrrhizic acid), glycyrrhetinic acid, Guangguo glycyrrhetinic acid, 3-hydroxy-hypochlorous acid, isoglycyrrhetinic acid, etc Flavonoids contain Glycyrrhiza glabra, flavonoids a, chalcone A and B 4 Main pharmacological actions The water extract can inhibit the secretion of gastric juice; the methanol extract can inhibit the release of some gastrin and promote the healing of acetic acid ulcer in rats; the decoction flow extract can inhibit the isolated intestinal tract and has the effect of adrenocorticotropic hormone; the liquorice extract, glycyrrhizin and glycyrrhetinic acid have the effect of promoting sodium in healthy people; the small dose of glycyrrhizin and glycyrrhetinic acid Acid can make thymus atrophy and adrenal gland weight increase; glycyrrhizin can reduce chronic hepatitis, cirrhosis, cholesterol content in blood and prevent arteriosclerosis; alcohol extract and sodium glycyrrhetinic acid can inhibit Staphylococcus aureus, tuberculosis, Escherichia coli, trichomonad, etc In addition, it can improve lipid metabolism, hemolysis, anticoagulation and sedation 5 The current situation of Glycyrrhiza uralensis is short of wild resources, and the commodity source mainly depends on planting and production The domestic liquorice can be directly seeded or transplanted At present, the main production mode is seedling transplanting The direct seeding growth period of this product is 3-5 years, the seedling transplanting growth period is 2-4 years (including 1 year of seedling), and the seed production needs to last for more than 4 years At present, the seed source mainly depends on the collection of wild liquorice The traditional view is that red color, tight skin, solid quality, powdery foot, yellow white cross-section, sweet and fragrant taste are the best products, while the modern view is that the content of glycyrrhizic acid, glycyrrhizin, glycyrrhizin, flavonoids and other effective components is high The future price of Glycyrrhiza uralensis is predicted in Inner Mongolia, the main production area The content and appearance of the newly dug domestic grass in a planting base in Ejina banner are close to that of the wild grass The price of the first-class large strip grass is 15 yuan, and that of the second and third-class large strip grass is 12-14 yuan Local operators generally believe that the price of Glycyrrhiza uralensis is low for many years, and the consumption of Glycyrrhiza uralensis uralensis uralensis uralensis uralensis uralensis uralensis uralensis uralen First, the wild licorice resources are decreasing day by day According to the statistics of relevant departments, due to the intensive mining, the wild licorice resources are scarce now Second, the implementation of national ecological and environmental protection measures Licorice is not only an important traditional Chinese medicine, but also an important desert vegetation The long-term mining not only reduces the licorice resources, but also causes serious damage to the ecological environment of the production area Therefore, the State Council issued a document on June 25, 2000 prohibiting the mining of wild licorice, managing the mining of licorice, and at the same time, adopting a quota system and a limited export Relevant laws and regulations have also been formulated in the provinces and regions of the main production areas to focus on the protection of wild resources and encourage artificial planting Third, the market demand is further increased The amount of licorice is large, which is called "ten square and nine grass" The annual amount of licorice (the total amount of wild and domestic species) is more than 30000 tons With the deepening of scientific research and development, licorice is used more and more widely, and the demand will continue to expand It can be seen that, on the one hand, there is a decreasing resource, on the other hand, there is a growing demand, the labor value cost is rising, and it is expected that the price of licorice will rise in the future.
