The Research Of Separation And Identification Of Panax' Root Exudates And Rhizosphere Soil Material In Allelochemical

Panax is Araliaceae Perennial Perennial herbs with Air Yangyin heat of Health-effectiveness is nourishing strong valuable medicinal herbs,ginseng But even for the more prominent obstacles to performance parameters for the elderly participants were again planted in the Senate Gen-up and plant illness and difficult Baomiao phenomenon,a result of low production,poor quality,the impact of its economic benefits.Ginseng has been a barrier even to the concerns of people,and many research workers in the old Senate microbial community changes and changes in soil properties were studied,and ginseng own chemical substances on the growth of this important factor has been overlooked.In order to reveal the obstacles for panax even mechanism,to seek a sense of the role of the toxic chemical substances,the author of the first methanol,ethyl acetate,n-hexane three different polar organic solvent extraction agent,from the Senate after Extraction of soil organic constituents of different polarity,from 20%methanol extract identified 23 kinds of substances,belonging respectively to alkanes,aromatic hydrocarbons,alcohols,aldehydes,acids,esters,such as different types.The control of these substances and literature belonging to the majority of the material sense,which is the three aldehydes 2-amyl methyl aldehyde,2---hexene aldehyde,7-16 ene aldehydes in the past have not been reported in the literature,Participation is possible by the unique soil material.In methanol extraction of the sample,a total effective identified seven kinds of substances(more than 800 index matching).Pentachloronitrobenzene except for pesticide residues,the other ingredients were three kinds of esters,the total content of about 10.90%.An organic acids,or about 78.8 percent,a ketone,or 3.06 percent, amine substances A,or about 1.02 percent.bitterness of the total content of the material and content of 78.8%, the content of the soil in the Senate in the methanol extract of has an absolute advantage in bitterness is a common sense of material,in a variety of the plant Allelochemicals in both exist,but its content is not very high proportion,but the soil in the Senate in the high proportion of that bitterness is panax may have an important component of the flu.Methanol extracts of two substances that otherwise 8-15-and 13 dimethyl carbonate under Rice's sense of the material is classified theory should be judged sense of material,but in other plant material of the flu have not been reported in the study,it may be unique to the panax allelochemicals.The Senate earth from ethyl acetate extract identified 43 kinds of ingredients.These elements belong to 10 kinds of fat alkanes,aromatic 9,three kinds of ketones,alcohols three kinds,and six kinds of acids,esters 12,the material composition in rather scattered,the document control,the majority of Allelochemicals types.Senate hexane extract soil organic constituents in the vast majority of the alkanes,and weak polarity.This is the choice of the solvent.Participation at the same time also shows that many of soil organic constituents are weakly polar substances,weakly polar solvents can be extracted.The analysis,we can see that in the Senate hexane extract soil,paraffin 15,three kinds of esters,five kinds of other substances.In larger quantities.But relatively few species.Content distribution is rather scattered,in the identification of the material effectively,both in its content below 1%.The experimental results can be seen from different polarity of the solvent has been made with the use of more comprehensive results.If what kind of overlooked them will lose some valuable material.This study also used to collect the red Shapi period of panax root exudates in the organic ingredients used by GC-MS method and the determination of the chemical composition of samples were analyzed and identified.Results from different solvent extraction and separation of the samples identified in a variety of organic compounds,the inspection documents,the majority of these ingredients are organic material of Allelochemical,the paper Another innovation is the first of panax residue decomposition of the ingredients conducted effective,the results confirmed the decomposition of ginseng in the sense of the existence of a variety of substances,including the highest percentage of bitter,and the Senate soil of methanol extract of the highest content of bitterness formed a causal relationship that is bitter panax generated by allelochemicals one of the main ingredients,and most of accumulation of soil and rhizosphere.Panax also found in the decomposition of hexanoic acid is heptanoic acid,2---caproic acid in the past have not been reported in the literature,it may be unique to the ginseng allelochemicals.
