Study On The Preparation And Clarification Of Banlandaqing

This paper mainly deals with the extraction and refinement of the effective constituents of banian daqing extracted by alcohol circumfluence alclohol filtering with orthorhombic method and single factor method .The conclusions are as follow: (l)The extraction ratio of effective abstraction of composition of banlandqing by filtering is lower than that by ethanol backset current .(2) Licorice root backset current with ethanol is first performed, then banlandqing filter.(3) The optimum extract condition is that banlandqing draw liquid to be best to is it filter with licorice root terms 8 ethanol consumption to ooze, oozing the speed of filtering of 5ml/min, the mark of volume of the ethanol is 75%.(4) Test shell gather candy , ZTC1+1 clarify pharmaceutical , fruit juice is it is it filter liquid except the miscellaneous result to ooze to board blue heavy blue and green leaf to clarify pharmaceutical three natural flocculant separately, find three to be result pretty much the same, shell by contrast gather candy clarify pharmaceutical to be a bit more excellent.(5) It join big hole absorb resin draw liquid refined process conditions to board blue heavy blue and green leaf to do in the test, and experimental result indicate indigo and under indigo jade so red that lead and do lotion not to must is it appraise by terms as index to lead, big hole absorb to get rid of miscellaneous result gather candy than shell , ZTC1+1 and fruit juice clarify pharmaceutical to be these three natural to flocculate result to clarify the pharmaceutical to be superior resin.Abstraction of effective composition and its refinment blue big blue and green leaf of the board of this text, established the foundation for developing the board blue big blue and green leaf preparation, and made meaningful exploration for application of new craft, new technology in Chinese patent drugs.
