The Study Of Glycyrrhiza Quality Evaluation In Different Places

This research centered around glycyrrhiza, glycyrrhiza resource, categorization,commercial specification grade,chemical composition,pharmacologic action, exploitation and utilization have been deeply comprehended;the research of micro-character,reaction of physic and chemistry have been completed;the conterts of effective component;extract, moisture ,ash have been determined. Evaluation the purity and the degree of adequate quality . All these are the elaborate base of identification, clinical application and production.Glycyrrhiza commodity comes from Nei Meng-gu, Xin Jiang,the north grassland region of Ning Xia, He Beix ShanXi and Gan Su,where have much wild resource. Since the new state was built,the amount of sell has taked on rising tendency,especially in recent 20 years,the tendency is larger and larger.Domestic and abroad demand is increasing.Market is better,which induce to cull and dig wild glycyrrhiza resource;so, wild resource has been destroyed. Recently,government takes measures to limit export.Shortage is worldwide question,reasonable utilization and plant in a large area is imperative.The research of effective composition provide rationale to evaluate inter quality.Glycyrrhiza can accommodate environment better,and grow in deep layer sand, calcium grassland , where has much planted glycyrrhiza;it likes light, cloudy, moist, drought.There are many essential components in glycyrrhiza,such as glycyrrhizic acid, flavanoids, watter soluble extraction,reducing sugar, amylumx amino acids,organic acidx many metal elements,and so on.There are many kinds of flavanoids, terpenoid, coumarin, amino acidx alkaloid, estrin, organic acid and so on have been separated and obtained.There arre 59 flavanoids have been separated from aerial parts,84 compounds from roots and stems; 133 flavanoids totally from glycyrrhiza.Pharmacologic research have proved that glycyrrhiza has the effectiveness of mending spleen, increasing breath, heat-clearing anddetoxicating, alleviating pain, coordinating the drug actions of a prescription.It is utended weakness of the spleen and stomach, tired and debilitation, cardiopalmus and short breath, cough and excessive phlegm, gastric cavity and expand, limbs contraction-anxious, pain, swell and sore, relief drug toxicity,and violenty.Glycyrrhiza is illustrious frequently used Chinese crude drug and industrial raw material,it has large demand in the world. Glycyrrhiza extensively utends foods, beverage, tobacco, chemical engineering, brewage, national defense, vocations and so on. Glycyrrhizic acid utends beerproduction,increasing foam and colour, consistance and fragrant,and alsoutents maufacture,...
