Summary of the invention
Purpose of the present invention is intended to overcome the defective of prior art, and a kind of content with scutellarin in the macroporous resin purified method raising Breviscarpine bulk drug is provided, and makes it reach required standard.
Preparation method with the refining Breviscarpine bulk drug of macroporous resin of the present invention is made up of following steps:
One, adopting model is the macroporous resin of D101 or AB-8, and the weight ratio of macroporous resin consumption and bulk drug consumption is 10-15: 1, and be solvent-loaded column with water;
Two, the preparation of Breviscarpine upper prop solution: getting scutellarin content is the Breviscarpine raw material of 75-85%, and being mixed with weight percent concentration with boiling water is 10-20%, again with lye pH adjustment to 7.0-7.5, dissolving filters, and obtains upper prop solution;
Three, the upper prop solution with step 2 adds on the macroporous resin column of step 1, and water is collected elutriant as the eluent wash-out, and is colourless substantially until elutriant;
Four, the elutriant of step 3 collection is 1-2 with acid solution accent pH, separates out yellow mercury oxide, leaves standstill more than 5 hours, filters, and throw out washes with water to neutrality, checks no Cl
-
Five, throw out oven dry, promptly.
The described macroporous resin type of step 1 is to handle qualified resin according to the working method of routine, and the working method of described routine is: with ethanol or acetone repetitive scrubbing, meet water until washings muddiness does not take place.The described alkali lye of step 2 is the alkaline solution of accent pH commonly used, as: 10% NaHCO
3Solution, sodium hydroxide solution of 5% etc.; Described solution can carry out centrifugation earlier before filtering, to improve filtration efficiency.The described acid solution of step 4 is the acid solution of accent pH commonly used, as: 20% hydrochloric acid soln, 15% sulphuric acid soln etc.
As the above-mentioned treating process of process, the content of scutellarin does not reach 90%, and repetitive operation is 1-2 time again, the second cellulose content can be brought up to more than 90%.
The macroporous resin that is adopted among the present invention is a kind of sorbent material commonly used, and the thick step that generally is used for plant constituent separates, and seldom is used for refining chemical ingredients.But it is the macroporous resin of D101 or AB-8 that unique distinction of the present invention just has been to adopt model, make refining Breviscarpine bulk drug, improve wherein that this technical barrier of content of scutellarin has obtained solution.
Processing step of the present invention is simple, is easy to suitability for industrialized production, has solved the refining difficult problem of Breviscarpine bulk drug for many years.Because macroporous resin absorption has been removed many impurity, make the Breviscarpine bulk drug of preparing reach the regulation of " drug standard " promulgated by the ministries or commissions of the Central Government record.
