Polygonatum Alternate Leaves Department Of Five Medicinal Plant Classification And Identification

In this paper, Polygonatum (Polygonatum) medicinal plants identified in the non-breeding period methodological research, including the Pharmacopoeia of the three kinds of income that is Yu-chu (Polygonatum odoratum Mill.), Huang-Jing (Polygonatum sibiricum Red.), Duohua Huang-Jing (Polygonatum cyrtonema Hua.), and no income Pharmacopoeia have medicinal use of three kinds of the Erbao Huang-Jing (Polygonatum involucratum (Franch. et Sav.) Maxim.), Rehe Huang-Jing (Polygonatum macropodium Turcz) Changgeng Polygonatum (Polygonatum filipes Merr.). This study was a nationwide survey of Chinese medicine resources and background to explore suitable identification method for field identification and through the preservation treatment, the experimental material.This study on Polygonatum odoratum field morphological analysis and morphological identification, on Polygonatum a preliminary classification of morphological type,In accordance with leaf style can be divided into wide-Yuzhu,narrow-Yuzhu.The principal component analysis and cluster analysis, combined with their morphological classification t test was validated,While redefining the basis of Polygonatum species identification,Differences in the past in the traditional sense with flowers, fruit and other reproductive organs based identification methods for the identification. Determined by leaf shape, stem shape, rhizomes form of identification methods as the main information,Identification of measurement information according to a database,In order to facilitate the use of mass appraisal.This method is simple, easy to master, to promote excellent, except Polygonatum plants, are also suitable for other species of plants,In theory, the resources would be better in the application of survey results.Microscopic identification and research on micro-characters. Using frozen section technique,Sliced of polygonatum in Beijing,And screening by experimental methods,To establish a new method for identification of surface microstructure on the dry leaves.Through the Comprehensive Assessment of morphology, on Polygonatum assess the feasibility of microscopic identification method to determine the leaf surface identification method for identification of the producer Polygonatum higher adaptability, rhizome cross section can assist identification of identification methods Polygonatum medicinal plants. Microscopic identification method is relatively simple, which leaves the surface of the producer identification method is more inexpensive method for the spread of good help, its adaptability for the common species are better, the microscopic part of the identification should be Identification of devaluation on the leaf surface film. Micro-characters, the characters such as leaf surface micro-identification method is simple, low cost, promote easy, but in terms of Polygonatum or not applicable, it can be extended to resource surveys, but the identification of monocotyledons, reservations.Physical and chemical identification of the study, for now, to polysaccharide differences as identified Polygonatum the basis of their identification standard, all influenced by many factors, such as the growth years, cultivation or wild, polysaccharide composition is different to equality issues identified. In addition to polysaccharide detection and identification methods, the operation is also more complicated. Therefore, Polygonatum polysaccharide constituents of the progress of new before, this time being used identification methods. Near infrared technology in the products, plants and identification of medicinal materials gradually rise, through the analysis of previous studies and near infrared identification technology in the use of Polygonatum, one can conclude that the method will occupy a larger plant identification of the components. As the 2005 Pharmacopoeia of China is also the method of income, and therefore, near-infrared identification law will gradually become the primary medicinal plant identification and identification of one of the mainstream approach, above, near infrared technology is simple, moderate cost, to promote easy widely applicable to various plant species, used in resource surveys identified the original plants have good prospects.By the content of the above,found that,Identification methods rely on a kind of identification of a large number of samples does not apply, in particular the context of Chinese medicine resources survey,Therefore,Identification of the initial establishment of multi-dimensional model,The introduction of the concept of systems biology,to use of one or a few identified ways the most characteristic of the identification, sequential depth, sequential identification.Select the advantages of each method of identification of the content identification,Not only saves time but also save costs and resources,Resources survey for the context of large sample survey is very useful.
