The aim of the study is to investigate the effects of concentration, intestinal segments, pH, inhibitors of proteins (P-gp), Na(+)-dependent glucose transporter (SGLT1) on the intestinal absorption of berberine, and to compare intestinal absorption of berberine in combinations. With phenol red as the indicator, in situ single pass intestinal perfusion (SPIP) model was used and intestinal absorption of pure berberine at concentrations of 36.70, 46.17 and 92.33 microg x mL(-1), simulated system of HLJDT (mixture of berberine, baicalin and geniposide), HLJDT with the concentration of berberine 92.33 microg x mL(-1) in perfusion solution of different intestinal segments (duodenum, jejunum, ileum, and colon) were determined by HPLC in combination with diode array detection (DAD). The results indicated that Ka values ofberberine at different concentrations had little significant difference among that obtained after perfusing via duodenum, jejunum, ileum and colon indicating that the absorption of berberine was mainly the passive diffusion. It was also suggested that SGLT1 and P-gp might exert some effects on the absorption of berberine. Ka and Peff values of berberine in a mixture of pure compounds and HLJDT for different intestine segments of rat showed an increasing tendency and was significantly different (P < 0.05) indicating that berberine in a mixture of pure compounds and HLJDT was assimilated better in small intestine. These results indicate that the intestinal absorption of berberine may be affected by compatibility of compounds. Additionally, berberine has wide absorption window and better absorption in colon.

[Objective] To find the method of pharmacokinetics experiment about Huanglianjiedu Decoction.[Methods] According to references about pharmacokinetics experiments on Huanglianjiedu Decoction,the article summarized the achievements in quantitative analysis,the influence of distill techniques and pharmacokinetics on indict components in Huanglianjiedu Decoction.This article attached importance to applying the technologies of PK-PD modeling and Data Mining in research of Chinese traditional medicine compound.[Conclusion] The pharmacokinetics study on Huanglianjiedu Decoction is just in the first step; thereby further studies will be taken on this decoction in order to reveal the active fractions and effect mechanism.

According to two theories,which are "traditional Chinese medicine researching is in the face of a complex opening gigantic system" and "Chinese materia medica compound(CMMC) is the natural combinatorial chemical libraries",the study on active fractions of CMMC has been facing to a complex system with a large number of data that is non-linear,multi-variable,and varieties related to each other.The thinking and method of "combinatorial screening" has been put forward based on these two theories,that is the principle "using the diverse structures of molecules to simulate the diverse organism" used in combinatorial chemistry and the data mining technique was taken into the study on complex system of CMMC.In order to create combinatorial libraries,the two methods were used to obtain the fractions of CMMC.Re-combination group of the CMMC was used,and various industrial separation techniques, such as resin,membrane,were used to replace the diversity of chemosynthesis routes to create "Building Block".Through data mining and knowledge discovery, the intrinsic correlation of CMMC "multi-components and multi-targets" between the chemical composition and the mechanism was carried out.The new technologies which aim at high-throughput screening of CMMC were explored,in order to provide the evidence for setting up an idea with "optimal separation" and optimization design about application system of refining technology.

Objective To establish the quality control standards of Gehuang Huoxue Capsules. Methods TLC methods for identification of Radix Astragali and Radix Gentianae Macrophyllae were established. A simple HPLC method was established for the determination of Puerarin. Results The spots on TLC plates were clear without interference in the blank reference. The liner range of Puerarin was 0.020 79～0.665 2 mg/mL, r= 1.000 0. The average recovery of Puerarin was 100.1% and RSD=0.92%. Conclusion The method is simple, accurate, reproducible and can be used for the quality control standards of Gehuang Huoxue Capsules.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.

The combination of Angelicae sinensis Radix (Danggui, DG) and Astragali Radix (Huangqi, HQ) is a popular herb pair commonly used in clinic for the treatment of blood deficiency syndrome in China. The aim of this paper is to study the interaction of DG and HQ nourishing and tonifying blood effects by response surface method. The blood deficiency mice were induced by injecting N-acetylphenylhydrazine (sc) and cyclophosphamide (ip). The blood deficiency mice were administrated intragastrically with DG-HQ extracts (0:1, 1: 5, 2:5, 2:3, 1:1, 3:2, 5:2, 5:1, 1:0). The changes of the peripheral blood indexes and organ indexes were observed. The indexes were integrated by comprehensive index method; the interactions of DG and HQ were analyzed by the response surface diagram established with Matlab software. The results showed that DG and HQ at most of their combination ratios had synergic effect. Within the range of 1:5 - 5:1, all of the extracts of DG-HQ showed synergic effect, and among which, high-doses had better effects than low-doses. The highest value (-1) of the synergic effect was showed when DG was 10 - 40 g at the same time of HQ as 90 -180 g, and DG was 50 - 100 g at the same time of HQ as 20 - 100 g. DG-HQ at all combination dosages within Chinese Pharmacopeia (DG: 6 - 12 g, HQ: 9 - 30 g) had certain synergic effect, and Danggui Buxue Decoction (DG: 6 g, HQ: 30 g) also was at this range. The results provided scientific basis to the clinical application of DG and HQ. And the response surface method was firstly applied to quantitatively evaluate the bio-activity change of herb combination, which provided a novel way for modern basic research on the interaction of herbs.
