Abstract
A nano-carthamiflavone medicine in the form of liquid injection, powder injection, or perfusion is prepared from carthamiflavone (50-85%) extracted from safflower, medical carrier and medical auxiliary. Its preparing process is also disclosed.
Description
Technical field
The invention belongs to technical field of traditional Chinese medicine pharmacy, be specifically related to a kind of nano-safflower flavone injection preparation and preparation method thereof.
Background technology
Flos Carthami is the dried floral of Compositae annual herb plant Flos Carthami CarthamustinctoriusL., it is one of blood-activating and stasis-removing of using always, effect with anticoagulant, anti-bolt, blood vessel dilating, wherein flavones ingredient is the class main active in the Flos Carthami, main active is a total flavones in the Flos Carthami injection of Chu Shouing in the market, flavones ingredient has the platelet aggregation effect of remarkable inhibition by ADP, thrombin, arachidonic acid-induction, also has the platelet activation effect that suppresses the platelet activating factor mediation; But in clinical practice, Flos Carthami injection poor stability [" time precious traditional Chinese medical science traditional Chinese medicines " the 12nd the 6th phase of volume of calendar year 2001,490, the stability study of Flos Carthami injection], a large amount of serious adverse reactions appears: cause anaphylactic shock 1.; 2. drug eruption; 3. therefore, the medical scientific research research worker should be carried out preparation research with carthamone in heating [Flos Carthami injection causes anaphylaxis, " medical Leader ", 2000,19 (6): 609], develops rapid, the safe carthamone preparation of a kind of onset; Therefore flavone compound, in the process of extracting purification carthamone effective site, should note temperature controlling to thermally labile in the Flos Carthami; Consult document and patent, in the process of extracting carthamone, adopt heated alcohol extraction more, and temperature is extracted in control; In purge process, there is report to adopt organic solvent extractionprocess, in handling the process that reclaims organic solvent, there is not fine control temperature yet, therefore can cause the content of carthamone in the Flos Carthami extract to reduce.
Liposome is the middle made superminiature spheroid carrier preparation of thin film that drug encapsulation is formed in the lipoids bilayer.The material that constitutes lipid bilayer (carrier) mainly contains phospholipid (lecithin, cephalin, fabaceous lecithin) and cholesterol etc., because existing hydrophilic group has hydrophobic group again in their molecular structure, when constituting spherical class Lipid Bilayer Structure, the structure that its hydrophobic group constitutes is relatively got up drug encapsulation.Liposome has the following advantages as the carrier of medicine: (1) this carrier can be protected enveloped; (2) control drug release effectively; (3), can control medicine in in-house distribution and the clearance rate in blood by changing liposome size and electric charge; (4) change certain physical factor, the permeability that temperature that for example changes the partial pH of medication, diseased region etc. can obviously change liposome membrane impels liposome optionally to discharge medicine; (5) after liposome enters in the body mainly by reticuloendothelial system phagocytic, can activate the autoimmune function of body, and drug main will be accumulated in histoorgans such as brain, liver and bone marrow, thus improve the therapeutic index of medicine, reduce the therapeutic dose of medicine and reduce drug toxicity; (6) liposome itself is to human body avirulence and immunosuppressive action.Therefore, liposome especially demonstrates obvious superiority in the brain diseases treatment at numerous disease.
Consult document and patent, do not retrieve the data of nano-safflower flavone injection preparation.
Summary of the invention
For these reasons, we are by a large amount of experimentatioies, Flos Carthami is adopted ultrasonic alcohol extraction earlier, and the control temperature is no more than 40 ℃, in purge process, we adopt D101 type macroporous adsorptive resins to be prepared, all concentration processs of the present invention adopt rotation wiped film vaporization instrument to carry out, and the control temperature is no more than 45 ℃, in whole extraction purge process, better controlled temperature, prevent in the Flos Carthami extract that the active component carthamone decomposes.
The carthamone extract be will obtain and chemical property and analysis of physical carried out, mix with preferred solvent, lipid according to its character, control temperature well, be prepared into nano-safflower flavone, be mixed with into aqueous injection, infusion solution, injectable powder with pharmaceutic adjuvant, pharmacodynamic study, nano-safflower flavone injection preparation of the present invention have characteristics safe, that pharmacological action is good.
