Studies On Quality Standard And Fingerprint Of Chinese Thorowax

Chinese thorowax is the root of Bupleurum chinense DC or the root of Bupleurum scorzonerifolium Willd of plant of Umbelliferae. It has issue in soothing the liver it is the strongly fragrant to solve,and rising Yang,etc.used in the cold and fevers and chills alternate, the chest coerces bloated pain,etc. Saikosaponin a and d are the main effective composition in the root of Chinese thorowax of traditional Chinese medicine, have pharmacology function in many aspects.This text has carried on several researches altogether: 1 , By handing in the experimental design and confirming the best process conditions that makes the root of Chinese thorowax of vinegar, in order to make it concoct the craft to standardize. 2, By relatively test the law confirming the best method to draw Saikosaponin sample of root of Chinese thorowax is: 5% methyl alcohol of ammonia water backset current 4, water saturation straight cube alcohol extract 20ml / time. 3 , Use HPLC to determine the content of the Saikosaponin of root of Chinese thorowax.4, Carry on the systematic quality standard to study to the crude drugs of root of Chinese thorowax of vinegar , determine the ash content , moisture , soak out the thing ,etc. Meanwhile , the thin layer is distinguished after determining the nature to Saikosaponin a, d. Regard Saikosaponin a and d content of root of Chinese thorowax as the index, track it's stability in 1 , 2 , 3 , 6 and 12 months. The result shows : Basic stability within one year of root of Chinese thorowax of vinegar. 5, Dopt the chromatogram law of the high-efficient liquid phase to carry on the preliminary research of the fingerprint...
