Summary of the invention:
In view of the foregoing, the inventor has carried out a large amount of experimental studies to the processing method of extraction separation osthole from the Chinese medicine Fructus Cnidii, determined the macroporous adsorbent resin method, being used for osthole extracts, separate, preparation technology's method of purifying, and finish the research of structure analysis conclusive evidence and accelerated stability test, obtain purity and be stabilized in osthole more than 98%, thereby finished the technology invention of osthole, with the pharmaceutical composition that contains osthole, and said composition is at the anti-curing oncoma of preparation, application in tumour radiation sensitivity and the leukocyte increasing medicine.
One object of the present invention is, discloses to adopt the macroporous resin adsorption elution method to obtain purity greater than 98% osthole monomer.
Another object of the present invention is, discloses osthole in the application that is used to prepare aspect antitumor, tumour radiation sensitivity, the leukocyte increasing medicine.
Further object of the present invention is, discloses and has contained the osthole for the treatment of significant quantity, reaches the pharmaceutical composition of forming with one or more pharmaceutically acceptable carriers.
The present invention discloses the preparation technology method of purity greater than 98% osthole in further detail.Technical scheme of the present invention is achieved by following content:
A kind of high purity cnidicin, it is the Chinese medicine Fructus Cnidii to be boiled through ethanol carry, macroporous adsorbent resin decolouring enrichment, and by resin separation purification obtains purity greater than 98% osthole in conjunction with recrystallization.Described macroporous adsorbent resin is NKA-9, NKA-12, D4020 or AB-8.
Specifically undertaken by following processing step:
(1) extract: take by weighing a certain amount of Fructus Cnidii medicinal material, boil with 60~95% ethanol and carry 3~4 times, each 1~2 hour, merge ethanol extract, concentrate and reclaim ethanol;
(2) separate: ethanol extraction through macroporous resin column, is flowed out water soluble component-I with before washing, discarding, flow point-II before 30~45% ethanol eccysis part; With 50~90% ethanol elution part-III, for containing the tonka bean camphor composition of osthole more than 60%;
(3) refining:, choose the NKA-9 macroporous adsorbent resin and carry out separation and purification, with hexanaphthene, chloroform: sherwood oil (40: 1~10: 1), ethyl acetate: sherwood oil (40: 1~10: 1) or normal hexane wash-out obtain the osthole crude product; Osthole obtains purity greater than 98% osthole with activated carbon decolorizing with methanol-water, alcohol-water, sherwood oil, normal hexane or hexanaphthene recrystallization.
(4) resin regeneration: regenerate behind the pigment of resin column with the absorption of wash-outs such as ethyl acetate, acetone, methyl alcohol or chloroform, reuse.
The present invention repeatedly repeats extraction, separation and process for refining, has used 4 solvent elution systems.Used 4 kinds of macroporous adsorbent resins of opposed polarity to separate decolouring absorption: NKA-12, NKA-9, D4020 or AB-8; Being used for the purified polymeric adsorbent is NKA-9, has optimized extraction and separation process.Product purity all remains on more than 98%, portioned product purity even can reach 100% (HPLC result).Utilize many batches of products of this explained hereafter, stable, favorable reproducibility.
Its stability is carried out accelerated tests investigate (high temperature, high humidity, strong illumination), found that it to high temperature, high humidity, stable, the nothing decomposition of strong illumination, purity and physical and chemical index are constant.Technical indicator reaches the requirement of a kind new medicine declaration, and technology is fit to suitability for industrialized production.

4Gy Cs
137Gamma-radiation full-body exposure ICR mouse anti is put test-results
Annotate: * P<0.01; Femur has the nuclear numeration for * 10
6/ L.
(2) dna content: irradiation back was taken off vertebra with the mouse neck on the 9th day and is put to death, and got a side femur, 5mM calcium chloride solution flushing marrow.The perchloric acid reaction solution that adds 0.2N is considered liquid and is measured absorbancy with ultraviolet spectrophotometer.
(3) get thymus gland, spleen, observe thymus index and spleen index.
Conclusion: osthole is to 4Gy Cs
137Gamma-rays full-body exposure ICR mouse anti is put test-results and is shown, osthole lowly has significant leukogenic effect to the white corpuscle that ray causes, than control group rising 32.5% (P<0.01).
Acute toxicity test:
6 every group of Kunming mouses, male and female half and half, respectively (soup is thickness very) all do not have death when oral administration gavage administration 800mg/kg, 1600mg/kg, 2000mg/kg, and diet, spirit are all normal.Effectively to press down cancer dosage be 1.00~2.50mg/kg and it is best, and medicine is very safe.
High purity cnidicin of the present invention and extracting method thereof are compared with prior art has following advantage:
(1) utilizes Fructus Cnidii extraction separation osthole, have the content height, the characteristics that extract yield is high.Yield is between 1~2%, and drug resource is abundant, cheap and easy to get.
(2) it is simple to adopt macroporous adsorbent resin method extraction separation osthole to have technology, separates and can accomplish scale production fast, and process stabilizing can repeat; Extracts active ingredients is complete, avoids the waste of drug resource; Resin can be regenerated, and solvent can recycle and reuse and the characteristics that reduce cost.
(3) to have effective constituent definite for osthole of the present invention, purity height, good stability, the characteristics of efficacy stability.
(4) because effective constituent is definite, the purity height, impurity is few, and low solvent residue, medicine have the characteristics of system stable and controllable for quality.
