Tripterygium glycoside-containing micro-emulsified gel transdermal preparation and preparation method thereof

The invention belongs to the technical field of medicinal preparations and relates to a tripterygium glycoside-containing micro-emulsified gel transdermal preparation and a preparation method thereof. The preparation method is characterized in that a gel matrix is added into microemulsion and the mixture is further processed into the tripterygium glycoside-containing micro-emulsified gel transdermal preparation. The tripterygium glycoside-containing micro-emulsified gel transdermal preparation comprises: by mass, 0.1 to 15% of tripterygium glycoside, 15 to 20% of one or more surfactants, 30 to 40% of one or more auxiliary surfactants, 15 to 25% of oil phases, 15 to 25% of water, 0.5 to 2% of one or more transdermal absorption promoters, and 0.5 to 5% of one or more gel base materials. Thetripterygium glycoside-containing micro-emulsified gel transdermal preparation is semitransparent or transparent, has nattier blue opalescence and a pH value of 6 to 10 and can form micro-emulsion having particle sizes of 10 to 100nm, can be processed into pasters so that drug transdermal delivery is realized, has low skin irritation, can be prepared by the simple preparation method, and has stable quality and good drug transdermal absorption promotion performances.

Application of Wubi Shanyao pills to preparation of POI (premature ovarian insufficiency) treatment drug

The invention discloses application of Wubi Shanyao pills to preparation of a POI (premature ovarian insufficiency) treatment drug. The Wubi Shanyao pills are prepared from rhizoma dioscoreae, herba cistanche, fructus schizandrae, semen cuscutae, cortex eucommiae, radix achyranthis bidentatae, rhizoma alismatis, radix rehmanniae praeparata, fructus corni, poria cocos, radix morindae officinalis and halloysitum rubrum. A female ICR mouse is subjected to intragastric administration by adopting tripterygium glycosides for 10 weeks to induce POI, molding is carried out, then the model mouse is continuously subjected to intragastric administration by adopting the Wubi Shanyao pills for 12 weeks, it is found that compared with a model control group, the Wubi Shanyao pill administration group hasthe advantages that the holding power of the model mouse can be obviously increased, the average estrous cycle days are shortened, the number of granular cell layers and the number of preantral follicles and sinus follicles are increased, the serum LH level is reduced, the Wubi Shanyao pills have a remarkable improvement effect on the POI mouse, so that the POI treatment or improvement effect isachieved, and good news is brought to the POI patient.

Tripterygium wilfordii medicinal material and method for determining wilforlidea in tripterygium wilfordii polyglycosides tablet

The invention provides a tripterygium wilfordii medicinal material and a method for determining wilforlidea in a tripterygium wilfordii polyglycosides tablet. The method comprises the following stepsof taking an ethanol solution of 0.1 mg.mL<-1> of wilforlidea as a reference substance solution; acquiring a corresponding volume ratio range by establishing and optimizing normal hexane, ethyl acetate, ethanol and water of a solvent system so that a distribution coefficient K of the wilforlidea in the solvent system is 0.5-2; optimizing and controlling a rotating speed of a liquid-liquid distribution chromatographic separation column and a flowing speed of a mobile phase, and detecting the tripterygium wilfordii medicinal material and the method for determining the wilforlidea in the tripterygium wilfordii polyglycosides tablet by combining high performance liquid chromatography. The method is simple in operation process, high in specificity and good in reproducibility, separation cost isgreatly reduced, a wilforlidea chromatographic separation degree is high, a product recovery rate is high too, a sample dosage is small, stability is good, precision is high, qualitative and quantitative accuracy is high too, and quality of the tripterygium wilfordii medicinal material and the tripterygium wilfordii polyglycosides tablet can be effectively evaluated.

Application of total flavonoids of clover in preparation of medicine for treating rheumatoid arthritis

ActiveCN106913610BEffective in treating rheumatoid arthritisEasily damagedAntipyreticAnalgesicsRheumatismArthritis
The invention relates to the technical field of medicines for conditioning rheumatoid arthritis, and discloses an application of total flavonoids of radix tetrastigme in rheumatoid arthritis treating medicines. The medicines are capable of conditioning the rheumatoid arthritis. A preparation process of the total flavonoids of radix tetrastigme comprises the following steps: prpearing 10-30kg of coarse powder of tubers of radix tetrastigme; conducting reflux extraction for 3 times with the addition of ethanol which is 65-75% in volume percentage; combining extracting solutions, decompressing the combined extracting solutions and recovering ethanol; keeping an obtained solution for a whole night and filtering the solution; extracting an obtained filtrate for three times by virtue of petroleum ether and conducting degreasing; processing the greased filtrate by virtue of a polyamide column; eluting the column sequentially by virtue of water and ethanol which is 90-95% in volume percentage; and decompressing an eluent of the ethanol which is 90-95% in volume percentage and recovering ethanol until a dried material is obtained, namely the total flavonoids of radix tetrastigme. At present, tripterygium glycosides, as a traditional Chinese medicine, can take a relatively good effect on treating the rheumatoid arthritis, however the tripterygium glycosides can cause various toxic and side effects, such as relatively serious injury to female ovaries and male sperms, and subsequently, clinical application is limited. According to the invention, the total flavonoids of radix tetrastigme, on treating the rheumatoid arthritis, is good in effect and free from toxic and side effects.
