Abstract
The present invention relates to a method for applying the macroporous resin to remove the pesticide residues by using the different parts of ginseng and panax quinquefolium as the raw materials. The quality of the present invention is mainly characterized in that: all the pesticide residues are less than 10PPb, and the content of galacturonic acid is 1.0 percent to 25.0 percent.
Description
Technical field: the present invention relates to one and use the method that macroporous resin is removed pesticide residue.Its main qualitative characteristics is: each item farming is residual all less than 10PPb, galacturonic acid 1.0%～25.0%.
Background technology: the genseng of having found, Radix Panacis Quinquefolii activeconstituents mainly contain several big type of saponin(e, GPS, volatile oil, amino acid and polypeptide etc.Have enhance immunity power, anti-ageing, promote learning and Memory function, detoxifcation, multiple physiological action such as antibiotic, diseases such as cardiovascular disorder, tumour, inflammation and digestive tract ulcer are had good effects.
Along with the discovery of genseng, Radix Panacis Quinquefolii polysaccharide enhancing immunity, physiological function such as antitumor, also deep day by day to STUDY ON POLYSACHAROSE, the GPS of separation and purification has tens of kinds at present.See that from the source these polysaccharide can be divided into ginseng polysaccharide, Stem and leaf of Radix Ginseng polysaccharide and genseng fructose.Wherein ginseng mainly contains acid heteroglycan and VISOSE; And the Ginseng Leaf is mainly contained acid heteroglycan; These mixed polysaccharide are present in cell walls as structural polysaccharide, mainly are made up of galacturonic acid, semi-lactosi, rhamnosyl, my sugar and pectinose (Ara), and structure is very complicated.
Investigation result according to national Chinese medicinal materials plant protection problem; At present the pest species of Chinese medicinal materials endangers heavily more, loss is big, like known genseng, Radix Panacis Quinquefolii more than 40 kind of infectivity disease and pest is arranged, normal take place kind more than 20 just arranged; Basically take chemical pesticide control, spray medicine 20-30 time every year on average.GeneraI investigation was once done to the pesticide residue of 300 plurality of Chinese in all parts of the country by Shanghai Univ. of Traditional Chinese Medicine, and the whole samples of result all contain phenyl-hexachloride, and great majority contain the residual amount of DDT.Chinese medicine is the treasure of the Chinese nation, its world market proportion increasing.And the market sales revenue of China is only about 4%, and its major cause is exactly the pesticide residue height.Therefore this problem must solve early, otherwise will seriously restrict the development of Chinese medicinal materials.Present method is to adopt absorption with macroporous adsorbent resin to remove pesticide residue, is superior to other plant and removes the residual method of farming.For example adopt supercritical extraction to remove the residual method of genseng middle peasant.Step is earlier genseng to be pulverized or section, and genseng is put into abstraction pool, makes the carbonic acid gas state that reaches capacity.Adjustment flow velocity, temperature, pressure, volume, purification entrainment agent, agricultural chemicals scavenging agent etc. are removed the residual purpose of farming to reach.
Summary of the invention: the objective of the invention is to find a kind of method of effective removal pesticide residue, it does not promptly destroy its effective constituent, does not lose productive rate, can effectively reduce the residual quantity of agricultural chemicals again.
