The purpose studies board La Gen is different the action of anti-current feeling virus that draws position, the sieve is singled out board the active position of La Genkang virus. The method uses the culture method outside gallinaceous embryo body to be opposite board different extraction place undertakes La Gen the efficiency that fights flu virus determines. Total water of result board blue root carries fluid (Ⅰ ) , chloroform extraction place (Ⅲ ) have prevent action with way and different way, fourth mellow extractive place (Ⅴ ) have different way to prevent action, freeze-dry water carries fluid (Ⅶ ) have prevent action with the way, these 4 place all have the active that fights flu virus. Place of extraction of chloroform of conclusion board blue root, fourth mellow extractive place is board the active position of La Genkang virus.
The purpose studies two kinds of chela add up to colophony A and B to be used at taking off to divide board the feasibility that La Gen extracts ion of the heavy metal in fluid. The method accuses to extract platform oneself in industrial pattern Chinese traditional medicine aspirant travel takes off heavy metal experiment, cream in order to work a collection of illustrative plates of rate, HPLC is similarly spend and heavy metal is taken off except rate to inspect index, compare the effect of two kinds of colophony to concerning index. After the result takes off heavy metal, work cream so that lead a loss under 7 ﹪ , through taking off heavy metal unit earning does the heavy metal content that cream each batches all under national set limit to. Applied colophony A takes off the likeness of HPLC a collection of illustrative plates that except heavy metal around doing creams to spend be more than 0.97, applied colophony B takes off the likeness of HPLC a collection of illustrative plates that except heavy metal around doing creams to spend very low. Conclusion colophony A suits to divide relatively board the heavy metal in fluid of blue root extraction.
Purpose from board La Genzhong extracts detached water-solubility polysaccharide, analyse its manage to change character, for board control of blue root quality and further development are used provide reference. The method basically uses chromatographic column of DEAE cellulose ion exchange, chromatographic column of Sephadex G 75 gel is detached and rarefied, apply efficient gel to filter color atlas way (the method such as HPGPC) , IR, TLC, UV is right board La Gen polysaccharide undertakes analysis and manage change property to consider compositive a structure. Result from board the depart in Lagen water-solubility polysaccharide is rarefied the PS1 of even polysaccharide constituent that gets differring 4 kinds, PS2, PS3, PS4, color atlas analysis makes clear all comprise by onefold xylose. Among them PS1, PS2, PS3, PS4 is 1.2 × respectively relative to molecular quality 104, 2.6 × 104, 4.2 × 103, 2.5 × 103. Conclusion 4 kinds of even polysaccharide first from board La Genzhong depart gets.
