In the prescription of Zhibai Dihuang Pills, there are eight kinds of ingredients, such as Rhizoma Anemarrhenae, Cortex Phellodendri Chinensis, Radix Rehmanniae Praeparata, Fructus Corni, Cortex Moutan, Rhizoma Dioscoreae, Poria and Rhizoma Alismatis. Zhibai Dihuang Pills, with the effect of nourishing yin and purging fire, can be used for the treatment of diabetes, Nephrosis syndrome, Uropoiesis infection, and so on. Zhibai Dihuang Pills have been widly used on the clinical treatment to cure yin deficient, and made into other dosage forms of preparations, such as tablets, capsules, granules. In recent years, along with the constant development of the clinical application, the application range of Zhibai Dihuang pills was extended correspondingly.Zhibai Dihuang honeyed Pills and water-honeyed pills, made with the powder of herbal ingredients without extraction, were collected into the Chinese Pharmacopoeia. The powder pills have the advantages of absorbing slowly, with affects lasting, but they also have the disadvantages of dissoluting too lowerly, absorbing poorly, and the granularity of powder might affect the effect of the pills.Effervescent preparation is a new dosage form progressed in recent years, with the advantages of quicklier collapsing, quicklier effection, and higher bioavailability, ect.In order to strengthen the effect of Zhibai Dihuang Pills, heighten their bioavailability and make them more convenient for patients, studies on the improvement of Zhibai Dihuang precedure and quality control methods were carried out, and a new patent drug--Zhibai Dihuang Effervescent Granules were developed. The herbal contents in the prescription was extracted. Orthogonal test experiment was used to choose the optimum extraction methods.In order to control its intrinsic quality to assure the clinical safety and effect, studies on the quality standard of Zhibai Dihuang Effervescent Granules were carried out. Thin layer chromatography ( TLC) and high performance liquid chromatography ( HPLC) were used. Cortex Moutan, Fructus Corni, and Cortex Phellodendri Chinensis were identifid by TLC, and the content of loganin in Zhibai Dihuang Effervescent Granules was determined by HPLC. The TLC identification methods were distinct and highly specific; the HPLC quantity determination method was simple, convenient, accurate and reproductable. The chosen analisys methods could be used for the quality control of Zhibai Dihuang Effervescent Granules.Initial stability test and acceleration stability test were car- ried for six monthes, and the results indicated that the samples had good stability.The studies on the Zhibai Dihuang Effervescent Granules will enrich Zhibai Dihuang preparations and application, strengthen their effect, enhance the bioavailability and increase selectivity and convenience for the patients.
