This study was designed to establish the stability of EGHB010, a combined hot water extract of Paeoniae Radix and Glycyrrhizae Radix. Test of coliform groups, sensory evaluations, contents of moisture, and the amount of paeoniflorin and glycyrrhizin were determined during storage at 4, 25 and 35℃ for 6 months. Coliform groups were not observed and moisture contents were maintained about 3.0% during the storage period. Sensory characteristics including color, taste, texture and appearance were tested over 3 points throughout the entire storage period. It maintained the commercial value during the storage period. Contents of paeoniflorin and glycyrrhizin as indicator components were remained stably for the storage period. The shelf-life of EGHB010 based on a linear response to zero of sensory evaluation with the highest correlation coefficient was predicted. Finally, the shelf-life of EGHB010 was expected for about 3 years to consider in safety coefficient. The shelf-life data of EGHB010 can be used to develop a functional health ingredient.

Two of the essential processes required for metastasis are neoangiogenesis and tumor cell invasion of basement membranes (BM) and extracellular matrix (ECM). Recently, data showed that herbs removing blood stasis has an anti-angiogenic effects. Tonifying vital Qi and eliminating pathogenic factor was a basic modality in Oriental oncology. In this study, we investigated several Qi and Blood tonics for potent angiogenic inhibitors. Methanol extracts of samples inhibited the proliferation of ECV-304 at the concentration of 100 ㎍/㎖. Zizyphi Fructus, Glycyrrhizae Radix, Angelicae Gigantis Radix decreased the gelatinolytic activity of MMP-9 from ECV-3Q4, at the concentration of 100 ㎍/㎖ in gelatin zymography. In in vitro invasion assay, herbs inhibited the invasion activity of ECV-304 by 53% of control (Ginseng Radix), 39% (Zizyphi Fructus), 36% (Angelicae Gigantis Radix), 25% (Glycyrrhizae Radix). Ginseng Radix inhibited the capillary-like tube formation of ECV-304 at the concentration of 160 ㎍/㎖, Angelicae Gigantis Radix and Paeoniae Radix Alba inhibited at the concentration of 320 ㎍/㎖. These results indicated that Ginseng Radix, Glycyrrhizae Radix, and Angelicae Gigantis Radix could be considered as potent angiogenic inhibitiors.

Many of researches have revealed that human intestinal microbiota is related to health. Several diseases like obesity, diabetes, and hypertension are affected by the microbiota directly and indirectly. So, interventions with food and drug have been tried to change a composition of the microbiota to better condition. However, few natural medicines have elucidated to date. To understand an influence on microbiota by plant materials including Glycyrrhizae Radix, the extract of medicines were administered to mice and the feces were collected before and after the administration. The feces were analyzed by terminal restriction fragment length polymorphism (T-RFLP). The changes in composition of mice gut microbiota were detected and analyzed. The data could be utilized to further study about biological activities of the plant medicines.

This study was performed to examine the antibacterial efecacy of topical agent extracted from Phellodendri cortex, Forsythia fructus and Glycyrrhizae radix as an alternative dermatological agent. Also, the most efficacious concentration of this agent and the skin-contact time inhibiting the vegetation of bacterial cells in various dilutions were determined. Five strains of Staphylococcus intermedius were exposed to various dilutions of this agent. The efficacy was assessed after exposure for time periods varying between 0 and 30 min. The antibacterial efficacy was shown to be the strongest at dilution of 1: 2. The number of viable organisms decreased significantly after 8 minutes of exposure time and was the smallest after 30 minutes of exposure time. This alternative dermatological agent is considered to be effective against Staphylococcus intermedius and has a potential to be a new topical agents far the treatment of pyoderma in dogs.

In order to study if Glycyrrhizae Radix (GR) has protective effects on hepatotoxicity of acetaminophen in mouse, one of the species which are sensitive to acetaminophen-induced hepatotoxicity, effects of GR on liver weight to body weight ratio, serum alanine and aspartate transaminase (ALT and AST) activities, hepatic UDP-GT2 activity, and histopathologic changes were determined in acetaminophen-treated mice. Liver weight to body weight ratio and UDP-GT2 activity in mouse liver were not altered by GR. However, GR pretreatment lowered serum ALT and AST activities by 77% and 90% respectively, and diminished the degree of centrilobular necrosis caused by acetaminophen in liver as determined by histopathologic observation. These results suggest a possible protective effect of GR against the acetaminophen-induced hepatotoxicity in mice.

$Yongkaksan^{\circledR}$ is a powdered crude drug which is used to treat cough and recommended it as an expectorant. It is composed of Platycodi Radix (11.7 mg), Senegae Radix(0.5 mg), Armeniacae Semen(0.83 mg) and Glycyrrhizae Radix(8.3 mg). For the identification of individual ingredients in such powdery mixtures, microscopic method may be considered to be efficacious due to requirement of a small amount of specimens. In this paper, effectiveness of this method will be exemplified by the identification of the ingredients in $Yongkaksan^{\circledR}$ which contains 4 powdered crude drug ingredients.

Result：Ginseng Radix(人參), Codonopsis Pilosulae Radix(黨參), Panacis Quinquefolii Radix(西洋參), Astragali Radix(黃芪), Atractylodis Rhizoma Alba(白朮), Dioscoreae Rhizoma(山藥), Dolichoris Semen(白扁豆), Glycyrrhizae Radix(甘草), Jujubae Fructus(大棗) and Mel(蜂蜜) may give rise to some side effects, allergic reaction or toxic symptoms in restoratives for invigorating qi(補氣藥). The representative methods of poisoning treatment in western medicines are stopping medication, washing out the stomach, promotion of vomiting, causing diarrhea, supplies of grape sugar and symptomatic treatment, etc. The representative methods of poisoning treatment in oriental medicine take advantage of various herbs. And Oriental medical doctor should meet symptoms as patients call for attention. In order to prevent against poisoning of restoratives for invigorating qi(補氣藥), the patients should keep usage, dosage and notes. Conclusion：We should pay attention to clinical using of Ginseng Radix(人參), Codonopsis Pilosulae Radix(黨參), Panacis Quinquefolii Radix(西洋參), Astragali Radix(黃芪), Atractylodis Rhizoma Alba(白朮), Dioscoreae Rhizoma (山藥), Dolichoris Semen(白扁豆), Glycyrrhizae Radix(甘草), Jujubae Fructus(大棗) and Mel(蜂蜜) in restoratives for invigorating qi(補氣藥).

Licorice, Glycyrrhizae Radix is widely used as a herbal medicines and a dietary supplements in East Asia. We employed high performance liquid chromatography electrospray ionization tandem mass spectrometry to determine liquiritin and glycyrrhizin in the Glycyrrhizae Radix. Liquiritin and glycyrrhizin in Glycyrrhizae Radix were ionized by positive ion pneumatically assisted electrospray and detected by HPLC-MS/MS in the multiple-reaction monitoring (MRM) mode using precursor ${\rightarrow}$ product ion combinations at m/z $436.2{\rightarrow}257.0$ and $823.4{\rightarrow}453.4$, respectively. The assay had a calibration range from 10 to 3,000 ng/mL. The limits of detection (LOD) of the liquiritin and glycyrrhizin were 0.4 ng/mL and 0.01 ng/mL, respectively. The reproducibility and repeatability (relative standard deviation) at different analyte concentrations varied from 103 to 113 % and 0.95 to 1.8 %, respectively. According to the above results, HPLC-MS/MS method permits assignment of tentative structures such as liquiritin and glycyrrhizin in the Glycyrrhizae Radix.
