Background: Inflammation is widespread in the clinical pathology and closely associated to the progress of many diseases. Triterpenoid saponins as a key group of active ingredients in Panax notoginseng (Burk.) F.H. Chen were demonstrated to show antiinflammatory effects. However, the chemical structures of saponins in the leaves and stems of Panax notoginseng (PNLS) are still not fully clear. Herein, the isolation, purification and further evaluation of the antiinflammatory activity of dammarane-type triterpenoid saponins from PNLS were conducted. Methods: Silica gel and reversed-phase C8 column chromatography were used. Furthermore, preparative HPLC was used as a final purification technique to obtain minor saponins with high purities. MS, NMR experiments, and chemical methods were used in the structural identifications. The antiinflammatory activities of the isolated saponins were assessed by measuring the nitric oxide production in RAW 264.7 cells stimulated by lipopolysaccharides. Real-time reverse transcription polymerase chain reaction was used to measure the gene expressions of inflammation-related gene. Results: Eight new minor dammarane-type triterpene oligoglycosides, namely notoginsenosides LK1-LK8 (1-8) were obtained from PNLS, along with seven known ones. Among the isolated saponins, gypenoside IX significantly suppressed the nitric oxide production and inflammatory cytokines including tumor necrosis $factor-{\alpha}$, interleukin 10, interferon-inducible protein 10 and $interleukin-1{\beta}$. Conclusion: The eight saponins may enrich and expand the chemical library of saponins in Panax genus. Moreover, it is reported for the first time that gypenoside IX showed moderate antiinflammatory activity.

The antiinflammatory activity of Phytolacca saponin and phytolaccagenin isolated from the roots of Phytolacca americana has been investigated. When Phytolacca saponin and phytolaccagenin were given parenterally exhibited potent inhibitory effects on acute edema in rats and in mice. while oral administrtion required 6 times more dosage in comparison with that of intrapertioneal injection. The anti-exudative and anti-granulomatous activities of the saponin showed as much as the dose of 8 times higher than that of hydrocortisone. The saponin appeared to be of no effects on adrenal, however, showed a severe thymolysis at high dose.

Inclusion complex formation of fenbufen with ${\beta}-cyclodextrin$ in water and in solid state was comfirmed by solubility method, ultra violet absorption, circular dichroism and infra-red spectroscopies, differential thermal analysis, and X-ray diffractometry. A solid complex of fenbufen with ${\beta}-cyclodextrin$ in 1 : 1 molar ratio was prepared by the freeze-drying method, its dissolution characteristics in water and its analgesic and antiinflammatory effect in mouse or rat were examined. The apparent release of fenbufen from the inclusion complex was significantly improved, hut no significant difference in its analgesic and antiinflammatory effect was found.

Eight derivatives of arylpropionic acid, arylcarbonylpropicnic acid, and arylhydroxybutyric acid were synthesized and their structures were elucidated on the basis of elemental analysis and spectral data. Also their antiinflammatory activities were evaluated by the method of the inhibitory effect on the carrageenin-induced rat paw edema and compared with phenylbutazone. Compound (I) exhibited 59% edema inhibition vs control when 100 mg/kg, was orally administered, whereas phenylbutazone showed 57.8% for 50mg/kg.

Eight compounds were isolated from the methanolic extract of the twigs of Celtis sinensis through repeated silica gel and Sephadex LH-20 column chromatography. Their chemical structures were elucidated as two triterpenoids, germanicol and epifriedelanol, two amide compounds, trans-N-caffeoyltyramine and cis-N-coumaroyltyramine, two lignan glycoside, pinoresinol glycoside and pinoresinol rutinoside, and two steroids by spectroscopic analysis.

Friedel-Crafts reaction of fluorene with methyl ${\alpha}$-chloro-${\alpha}$-(methylthio)acetate 1 gave methyl $\alpha$-methylthio-2-fluoreneacetate 2. Cicloprofen 8, a potent antiinflammatory agent, was prepared by methylation of 2 followed by reductive desulfurization of methyl 2(2-fluorenyl)-2-(methylthio)propionate 6 and hydrolysis of methyl 2-(2-fluorenyl)propionate 7.

The studies on concurrent administrations of herb preparations(Daesiho-tang, Daehwangmogdanpi-tang, Dohaegseunggi-tang, Baenongsangeub-tang and Jeoryeong-tang) with indomethacin and tetracycline were carried out to investigate the antiinflammatory, antimicrobial, liver-protective and antiulcer activities. The results showed that the concurrent administrations of herb preparations with indomethacin and tetracycline increased significantly the antiinflammatory activities and antimicrobial activities respectively, and also improved the liver-protective activities and antiulcer activities against indomethacin or tetracycline-induced liver defect and Shay ulcers in rats, respectively.

Simultaneous enantioseparation of nine racemic non-steroidal antiinflammatory drugs (NSAIDs) for their accurate chiral discrimination was achieved by cyclodextrin (CO) modified capillary electrophoresis in the normal polarity (NP) mode and in the reversed polarity (RP) mode. The NP mode employed neutral tri-O-methyl-${\beta}$-cyclodextrin (TM${\beta}$CD) as a selector dissolved in MES buffer (PH 6.0). (omitted)

The methanol extract of the root of Artanema sesamoides Family Scrophuilariaceae (MEAS) was investigated for possible analgesic and anti-inflammatory effects in animals. Three models were used to study the extract effects on nociception, which were acetic acid-induced writhing response, hot-plate method and the tail flick test in mice. The antiinflammatory effects were evaluated using carrageenan, dextran, histamine and serotonin induced rat paw oedema (acute) and cotton pellet induced granuloma (chronic) models in rats. Results of the study revealed that the extract exhibited significant (P < 0.001) analgesic effect at a dose of 50, 100 and 200 mg/kg b.w p.o in mice in all the models. In acute model, the MEAS also exhibited significant (P < 0.001) antiinflammatory effect in all the above mentioned doses. In chronic model (cotton pellet induced granuloma) the MEAS 200 mg/kg and indomethacin 10 mg/kg showed that inhibition of granuloma formation 25.0% and 47.7% respectively (P < 0.001). The MEAS and indomethacin were effectively preventing the transudation of the fluid. Thus, the present study revealed that the methanol extract of the root of Artanema sesamoides exhibited significant analgesic and antiinflammatory activity.
