Physiological Activity And Active Ingredients In Ginseng Preservation Storage Research

Ginseng(Panax ginseng C.A.Mey),as a new resource food,in food,health care products,cosmetics are popular in the areas of application.Fresh and due to the limitation of origin,applications received great impact.This article USES the vermiculite and perlite as the storage medium,different storage time ginseng saponins,volatile oils,polysaccharides,protein content and activity of SOD,POD,CAT change,select suitable for ginseng fresh medium.(1)using HPLC method,the different storage time and storage medium saponin content detection,the content of saponins as growing volatility,nine kinds of saponins in measurement(March 7)0.7381% ~ 1.68%(May 7);Pharmacopoeia prescribed three kinds of saponins measurement(March 7)0.3784% ~ 0.3784%(May 7),the test results of different media: perlite outdoor growth > soil,vermiculite,perlite > vermiculite with results ginsenosides determination,perlite is suitable for ginseng preservation storage;(2)using GC-MS analysis,different storage time and different storage media influence on volatile components,starting from the stored volatile oil content increased: on March 17,0.0271(g/g)-27 April 0.0379(g/g),volatile oil storage quantity overall trend;Different storage media content of volatile oil as follows: perlite > vermiculite > outdoor growth vermiculite,perlite > soil.Volatile components in result determination,perlite is suitable for the ginseng preservation storage;(3)using the phenol sulfuric acid method at different storage time and different storage medium of polysaccharide composition and the effect of ginseng polysaccharide of consumption,compared with the natural growth of ginseng,reduce nearly two-thirds,from the perspective of the polysaccharide several are adverse to ginseng storage medium.(4)to kjeldahl determination to explore different storage time and storage medium fresh ginseng water soluble protein content changes,the dormant protein content shows the tendency of decrease.Different media measurement results show that: compared with the natural growth,fresh-keeping ginseng protein,outdoor growth > perlite keeping fresh > vermiculite,vermiculite,perlite keeping fresh > soil preservation,think in terms of protein,compared with the outdoor growing ginseng,perlite and vermiculite can be used in the ginseng preservation.(5)with a taproot and spore as raw materials,different storage time and different storage medium fresh ginseng SOD,POD,CAT enzyme activity changes: different storage time ginseng root SOD,POD,CAT activity smoothly before germination,germination after rapid ascension,spore is at the early stage of germination,and the overall activity is not high.Taproot different storage media enzyme activity of size: soil > perlite > vermiculite vermiculite > perlite > normal outdoor conditions;Spore enzyme activity of size: outdoor growth soil > > perlite > perlite > vermiculite vermiculite.Any fresh processing can reduce the ginseng stem leaf growth and development;At the same time could reduce ginseng growth activity,therefore from the SOD,POD and CAT enzyme activity test results,and ginseng growth than outdoor,pearlite can be used in the ginseng preservation.Conclusion: pearlite can be used to ginseng preservation,storage process,but should add nutrients in pearlite,reduce their metabolic cost.
