Paeoniae Radix Rubra is a preparation consisting of desiccated roots of Paeonia lactiflora PALL (belonging to Ranunculaceae). Paeoniae Radix Rubra is used as a medicinal herb in Asian countries to treat many diseases. Ethanol- or water-based extracts of Paeoniae Radix Rubra were prepared and tested on RAW 264.7 cells, a murine macrophage cell line. The expression of some pro-inflammatory proteins, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 was detected by Western blot analyses, while PGE2 expression was quantified by ELISA. Both the water and ethanol extracts of Paeoniae Radix Rubra suppressed LPS-induced nitric oxide (NO) production and exhibited cell toxicity in accordance with increased NO production. Also, both extracts reduced the expression of COX-2 and iNOS, and inhibited phosphorylation of ERK1/2 in LPS-stimulated RAW 264.7 cells. Extracts prepared from Paeoniae Radix Rubra contain anti-inflammatory agents that inhibit the iNOS and MAPK pathways.

In traditional oriental medicine, Gentianae Radix has been used clinically for clearing away 'heat', removing dampness and purging fire in the liver and gall bladder. However, there has been a lack of studies regarding the effects of Gentianae Radix on the immunological activities. The present study was conducted to evaluate the effect of Gentianae Radix on the regulatory effects of cytokines and nitric oxide(NO) for the immunological activities in Raw 264.7 cells. After the treatment of Gentianae Radix MeOH extract, cell viability was measured by MTT assay, and NO production was monitored by measuring the nitrite content in culture medium. The expression of COX-2 and iNOS was determined by immunoblot analysis, and the content of levels of cytokines in media was analyzed by ELISA kit. Results provided evidence that Gentianae Radix inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), $interleukin-l{\beta}$ $(IL-l{\beta})$ and IL-6, and the activation of phospholylation of inhibitor ${\kappa}B{\alpha}$ ($p-I {\kappa}B{\alpha}$) in Raw 264.7 cells activated with lipopolysaccharide (LPS). These findings suggest that Gentianae Radix can make anti-inflammatory effect, which may playa role in adjunctive therapy.

Glycyrrhizin (GA) content in licorice was determined by a couple of methods using HPLC, respectively. In Method(I), GA content itself was determined from the licorice aqueous extract, while in Method (II) glycyrrhetinic acid (GHeA ; the aglicone of GA) content corresponding to the quantity of GA was measured from the chloroform extract of the hydrolyzed product of licorice aqueous extract. A reverse phase column Hibar Lichrosorb RP-18 (E. Merck) was used as the stationary phase. As the mobile phase MeOH: $H_{2}O$(0.05M-$NaH_{2}PO_{4}$)=58 : 42 solution in Method (I), and MeOH: $H_{2}O $: AcOH=78; 19: 3 solution in Method (II) were suitable, respectively. The value obtained by Method (II) appeared slightly higher than that by Method (I). The effect of some other herbal drugs on the assay of GA quantity in mixed sample was also observed in both above two methods. By Method (I) Cassiae Cortex, Rehmaniae Rhizoma, Paeoniae Radix, and Angelicae Radix gave the subtractive effect on the amount of GA compared with the value from licorice alone. In the case of Method (II) Cassiae Cortex and Rehmaniae Rhizoma appeared to have subtractive effect but Paeoniae Radix and Angelicae Radix scarcely showed any influence. Pachymae Fungus did not affect the GA content at all. It seems that glycyrrhizin in licorice interacts with certain components of other herbal drugs.
