Description
Technical field
The present invention relates to a kind of supercritical CO
2Extract the method and the composition of prepared from active ingredients of tripterygium wilfordii terpenoid, belong to the extraction and separation technology of Chinese medicine Radix Tripterygii Wilfordii active ingredient.
Background technology
Radix Tripterygii Wilfordii (Tripterygium wilfordii Hook f.) is the Celastraceae tripterygium plant, the record of Chinese medicine voluminous dictionary, have expelling wind and removing dampness, removing obstruction in the collateral to relieve pain, reducing swelling and alleviating pain, the parasiticidal effect of detoxifcation, the clinical autoimmune diseasees such as rheumatoid arthritis, chronic nephritis and lupus erythematosus that are used for the treatment of, be used for the anti-rejection treatment of organ transplantation in recent years, all obtained better curative effect.Modern study finds that in succession Radix Tripterygii Wilfordii has effects such as antiinflammatory, anti-immunity, antifertility, antitumor, antibacterial activity.So far isolated 200 number of chemical monomers from Radix Tripterygii Wilfordii, wherein Diterpenes, sesquiterpene alkaloids class, triterpenes are main active.
Aspect the Radix Tripterygii Wilfordii preparation research, commercially available Glucosidorum Tripterygll Totorum and thunder rattan sheet are arranged; After the nineties, the development of Radix Tripterygii Wilfordii preparation research is swift and violent, and special research aspect slow release, controlled release will produce important function to raising Radix Tripterygii Wilfordii curative effect, reduction toxic and side effects.The Radix Tripterygii Wilfordii preparation has tripterygium total terpenoids sheet, Radix Tripterygii Wilfordii microencapsule tablet, Radix Tripterygii Wilfordii drop pill, the double-deck bolt of Radix Tripterygii Wilfordii, Radix Tripterygii Wilfordii cataplasma at present.
The Radix Tripterygii Wilfordii complex chemical composition, pharmacological action is extensive, and important clinical application value is arranged.But, limited the popularization of clinical practice because the Radix Tripterygii Wilfordii toxic and side effects is bigger.Should further strengthen pharmaceutical chemistry and pharmacological action and Study of Clinical Application to Radix Tripterygii Wilfordii, extraction, purification, the effective ingredient that synthesizes high-efficiency low-toxicity or derivant improve its safety and using value, for the further development and use of Radix Tripterygii Wilfordii lay the foundation.
The method that the tradition prepared from active ingredients of tripterygium wilfordii extracts mainly contains decoction and alcohol sedimentation technique, water is put forward chloroform extraction method, alcohol extraction ethyl acetate extraction method etc., goes to dissolve with the solvent of opposed polarity according to polarity " similar mixing " principle of material and extracts the polarity composition similar to it.There is significant disadvantages in traditional extraction process:
(1) extraction efficiency is low: a lot of effective ingredient only extract a part sometimes, and remainder is but outwelled with medicinal residues, causes the waste of Chinese herbal medicine resource;
(2) production cycle long, production efficiency is lower;
(3) selectivity is bad: many invalid impurity and toxic component together extract with effective ingredient, and the concentration of effective ingredient is low, and toxic component content is higher, and multiple solvent extraction process all can't overcome the big shortcoming of toxicity;
(4) effective ingredient is easily destroyed: contact owing to the temperature height, with air etc., thermal sensitivity composition in the medicine, easy oxidizing component are damaged;
(5) drug quality and class are lower: organic solvent has residual after the lipotropy extracts active ingredients.
Summary of the invention
The object of the present invention is to provide a kind of supercritical CO
2Extract the method and the composition of prepared from active ingredients of tripterygium wilfordii terpenoid, the drug effect height of the prepared from active ingredients of tripterygium wilfordii terpenoid that this method is extracted and toxic and side effects is low.
The present invention is realized by the following technical programs, a kind of supercritical CO
2Extract the method for prepared from active ingredients of tripterygium wilfordii terpenoid, it is characterized in that comprising following process: Radix Tripterygii Wilfordii is crushed to 10～200 orders, be dipped in by Radix Tripterygii Wilfordii and ethanol mass ratio 2: 1-1.5 in the ethanol entrainer of mass concentration 55～85%, at extraction kettle with supercritical CO
2For solvent extracts, its operating condition is: temperature is 30～50 ℃, and pressure is 20-40MPa, CO
2Flow velocity is 10-30kg/h, extracts 60～150min.
Extract the composition of prepared from active ingredients of tripterygium wilfordii terpenoid with said method, it is characterized in that comprising sesquiterpene alkaloids, abietane type diterpene and triterpene carboxylic acids, the mass ratio of three compounds is: sesquiterpene alkaloids 30-50%, abietane type diterpene 25-45%, triterpene carboxylic acids 5-15%; In addition, the mass content of triptolide is 0.05-0.15%, and the tripterine mass content is 0.1-0.5%.
The present invention compares with other extracting method, and technical process is simple, regulates the ratio of three class active chemicals in the extract effectively, obviously is different from the extraction of traditional handicraft; Effective component extraction rate height, triptolide extraction ratio are 200-400%.Drug effect is 3-4 a times of commercially available prod, and toxicity is the 20-50% of commercially available prod.
