ABSTRACT
Fecal Tibetan medicines have a long history of application in China, with a good clinical efficacy. In order to promote the development and modernization of these medicines, we consulted ancient and modern Tibetan medicine literatures to collect and summarize the names, original species, natures, flavor, functions and processing methods of fecal Tibetan medicines. A total of 35 fecal Tibetan medicines were collected, such as Jiufen, Heibingpian, Langfen, Mafen, Goufen, Gezifen. The most commonly used medicines were Jiufen and Heibingpian. Both were mainly used for the treatment of indigestion, food abdominal distension, gastric ulcer, and other gastrointestinal diseases. At present, there are only a few studies on the active ingredients, pharmacodynamics and mechanism of action of these medicines. Therefore, further study shall be conducted. The regulation of gut microbiota may be a new way to evaluate the effectiveness of fecal Tibetan medicines and their mechanism of action.
ABSTRACT
Object To screen the prescriptions of JIUFEN SPRAY Methods Four prescriptions were primarily obtained from 19 prescriptions of JIUFEN SPRAY on the basis of their stability and spraying effect, then the obtained four prescriptions were screened further according to transdermal rate of them Results Prescription 17th was considered to be the best as its high stability, spraying effect and transdermal rate Conclusion The optimal prescription of JIUFEN SPRAY consisted of 20% alcohol solution of sample, 3% borneol and 5% glycerine
ABSTRACT
Objective: To screen the receiving solution used to study the transdermal absorption of strychnine in Jiufen spray. Methods: With recovery,Q-T equation and transdermal speed constant as the parameters, the improved Franz-cell and the skin of SD rats were used to screen the receiving solution from saline, saline-alcohol (7∶3,v∶v), pH phosphate buffer solution-alcohol (88∶2,v∶v), pH 7.4 phosphate buffer containing 25% alcohol. Results: The comparison of the inter-day and intra-day recoveries,Q-T equation and transdermal speed constant showed that saline-alcohol(7∶3) was the best for the study. Conclusion: It is indicated that saline-alcohol(7∶3) was the best receiving solution for the transdermal absorption study of Jiufen spray.
ABSTRACT
Objective: To study the transdermal releasing rule of the preparation of Jiufen Spray.Methods: Improved Franz diffuser was applied to transdermal experiment with TLC scanning method.Results: Q T (quantum time) equations of Jiufen Spray are strychnine:Q=220.941t- 486.006 , brucine:Q=208.146t-454.629, ephedrine:Q=177.691t-247.826. The study on releasing rule suggests the accumulative amount of transdermal drug increases with time, but the releasing speed is roughly stable, the total releasing ratio of 12 hours is about 50%. Conclusion: Jiufen spray could surmise to maintain relatively stable plasma drug concentration.
ABSTRACT
AIM: To elevate the stability of the volatile oil in Jiufen Cataplasm (Semen strychni,Herba ephedrae,Oilbanum and Myrrha) with the help of inclusion with ?-Cyclodextrin. METHODS: The quality of the volatile oil in Jiufen Cataplasm before and after stability test was examined by thin layer chromatography and differential thermal analysis and thermogravimetric analysis. RESULTS: The combination of volatile oil and ?-cyclodextrin could form stable inclusion compound that helped constant in before and after inclusion. CONCLUSION: The process of enclosure with ?-CD can keep the active components of the volatile oil in Jiufen Cataplasm.
ABSTRACT
Objective: To optimize the extraction process for Semen Strychni and Ephedra Sinica in Jiufen Powder. Methods: To determine the content of strychnine, brucine and ephedrine in extract solution by orthogonal design and TLC. Results: The volume of solvent and the number of times of extration have notable effect for extraction. The best conditions are 10 times of the herb quantity of water, extract three times, 1 hour per time.
ABSTRACT
OBJECTIVE:To establish the quality method control of Jiufen spray,a percutaneous administration preparatio_n.METHODS:To determine the contents with TLCs method.The thin-layer plate was made of silica gel GF254. The spread out agent was chloroform-methanol-ammonia solution(4mol/L)(2∶6∶1). Dual wavelength scanning:strychnine and brucine:?s=254nm,?r=325nm;ephedrine:?s=500nm,?r=440nm.RESULTS:The within-day recoveries of strychnine,brucine and ephedrine were 99.048?2.388,99.532?0.958 and 99.504?0.555;the between-day recoveries were 98.796?1.058,99.58?0.476 and 99.42?0.838;the contents were(1.474?0.047)%,(1.372?0.052)%and(1.506?0.064)%(n=4) respectively.CONCLUSION:This method is stable and reliable and can be used for determination of the contents of this preparation.
