Abstract

The present invention discloses a process for enrichment of ligustilide, which comprises the following steps: (1) Preparing crude vegetable oils from Ligusticum chuanxiong Hort; (2) adding petroleum ethers in 5-fold volume of the curde oil, whose boiling range is 30-60 deg.C or 60-90 deg.C; (3) Packaging and short column with D: H ratio of 1:1.3-1:1.5 using silica gel with 80-200 mesh in 1.6- to 2-fold volume of the curde oil to process said petroleum ether solutio; (4) after all the solution has passed through said column, washing the column with petroleum ethers in 1- to 2-fold volume of the curde oil; (5) Washing the column again with petroleum ethers in 12- to 16-fold volume of the curde oil, collecting the eluate, concentrating to remove completely the ethers, thereby giving the ligustilide oil, which can be used for preparing soft capsules and liquid hard capsules. The advantages of the present invention are: The ligustilide yeild is high and amounts to 50-60% in the ligustilide oils after enrichment. While the energy and production cost is low. Moreover, the operation process and equipment is simple, thus applicable for industrial scale production.

Description

A kind of technology of enrichment Z-ligustilide and preparation thereof
Technical field
The present invention relates to a kind of technology and preparation thereof of enrichment Z-ligustilide, refer to especially a kind ofly from Ligusticum wallichii, to extract, the technology and the preparation thereof of enrichment Z-ligustilide, belong to modern Chinese traditional medicine field.
Background technology
Z-ligustilide is one of main effective constituent in the Ligusticum wallichii, has anti-cerebral ischemia and improves cerebral blood flow (CBF), is used for the treatment of the various symptoms that caused by cerebral ischemia.
Because the pure product of Z-ligustilide are unstable, all use at present with the form of Rhizoma Chuanxiong oil, the method of Rhizoma Chuanxiong oil used water steam distillation obtains, Z-ligustilide content can reach more than 50% in the Rhizoma Chuanxiong oil that obtains from Ligusticum wallichii, but because production process needs long steam heating (reaching several days) energy consumption very big, gained Rhizoma Chuanxiong oil collecting amount is very low, and the yield of Z-ligustilide is lower.The also available CO of Rhizoma Chuanxiong oil 2Supercritical extraction method extracts, but Z-ligustilide content in the gained Rhizoma Chuanxiong oil is used the HPLC internal mark method determination with Z-ligustilide reference substance (purity reaches more than 98%), and its content has only 5~9%, and slightly oily with the Ligusticum wallichii of 85% ethanol room temperature dipping gained, its Z-ligustilide content only is 14%~18%.Therefore, study a kind of simplely, the process of enriching that can make Z-ligustilide content reach the ligustilide oil more than 50% has Practical significance.
Summary of the invention
The technology that the purpose of this invention is to provide a kind of enrichment Z-ligustilide.
Another object of the present invention provides the pharmaceutical preparation that is rich in Z-ligustilide.
For achieving the above object, the present invention is by the following technical solutions:
A kind of technology of enrichment Z-ligustilide comprises the steps:
(1) the preparation Ligusticum wallichii is slightly oily;
(2) overstriking oil 5 times of amounts, boiling ranges are the sherwood oil of 30~60 ℃ or 60 ℃~90 ℃, must petroleum ether solution;
(3) with 80~200 purpose silica gel of~2 times of amounts of thick oily 1.6 times of amounts, dress up short column, diameter and aspect ratio are 1: 1.3~1: the 1.5 above-mentioned petroleum ether solution of processing;
(4) after petroleum ether solution flows to end, wash post with the sherwood oil of 1~2 times of amount of thick oil in post;
(5) wash post with the sherwood oil of thick oily 12~16 times of amounts, collect elutriant, be concentrated into sherwood oil to the greatest extent, promptly get ligustilide oil.
The described method of the thick oil of Ligusticum wallichii for preparing of step (1) is for flooding Ligusticum wallichii or CO with 85% ethanol room temperature 2Supercritical extraction obtains slightly oil of Ligusticum wallichii.
Described 85% ethanol room temperature dipping is meant that the raw material that will contain Z-ligustilide floods 3 times through four times of amount 85% ethanol room temperatures, obtains slightly oil of Ligusticum wallichii.
Described CO 2Supercritical extraction is meant and will contains the raw material of Z-ligustilide through CO 2Supercritical extraction, extraction conditions is: pressure 34.5MPa, 60 ℃ of temperature, properties-correcting agent ethanol 0.3ml, 3 hours extraction time, the Rhizoma Chuanxiong oil that obtains.
Present method is utilized following principle enrichment Z-ligustilide: silica gel adsorption, the applied sample amount of overload.With common upper column quantity down can not the wash-out Z-ligustilide low polarity solvent, can separate eliminating than the more weak impurity of Z-ligustilide absorption, the wash-out Z-ligustilide, but can not adsorb stronger impurity than Z-ligustilide by wash-out, thus reach the purpose of purification enrichment Z-ligustilide.
With the ligustilide oil 25%~50% (its Z-ligustilide content 50%~60%) of enrichment processing back gained, plam oil 3%~6%, hydrogenated palm kernel oil 3%~6%, phosphatidase 12 %~4% and salad oil 42%~59%.Being mixed with soft capsule content, is rubber with glycerine-gelatin, is pressed into soft capsule, and every soft capsule contains Z-ligustilide and is not less than 25mg and every soft capsule and contains Z-ligustilide and be not less than 50mg.
With the ligustilide oil 20~80% (its Z-ligustilide content 50%~60%) of enrichment processing back gained, fat-soluble excipient such as salad oil 80~20%, can becomes liquid hard capsule, and every hard capsule contains Z-ligustilide and is not less than 50mg.
The test of pesticide effectiveness shows that this product has anti-cerebral ischemia, is used for the treatment of the various symptoms that caused by cerebral ischemia.
Advantage of the present invention is: the ligustilide oil of back gained is handled in enrichment, and through being standard with the Z-ligustilide reference substance, HPLC measures, and the content of Z-ligustilide reaches 50~60% in the ligustilide oil.Energy low consumption, all technological process except that enrichment process, all is at room temperature to operate; Solvent for use and silica gel can be recycled, and cost is low; Z-ligustilide yield height; Technological operation is simple; Required equipment is simple, is suitable for industrialized production.
