This study was performed to establish an analytical method for the standardization of Angelicae Dahuricae Radix as a functional ingredient. We established six compounds including oxypeucedanin hydrate (1), byakangelcol (2), oxypeucedanin (3), imperatorin (4), phellopterin (5) and isoimperatorin (6) as marker compounds of Angelicae Dahuricae Radix. An analytical method using Ultra Performance Liquid Chromatography (UPLC) was established and validated for marker compounds of Angelicae Dahuricae Radix. The specificity was confirmed by the chromatogram from UPLC and the value of coefficient determination was also higher than 0.999, indicating high linearity. The relative standard deviation (RSD) and recovery of marker compounds were less than 5% and in the range of 90- 110%, respectively, which means that this method has high accuracy and precision. Therefore, this analytical method could be used as basic data for the development of functional ingredients for health functional food of Angelicae Dahuricae Radix.

The purpose of this study was to investigate the whitening effect of Angelicae dahuricae Radix water extract (ADWE) by its application on artificial tanning spots which were induced by 1,500 $mJ/cm^2$ of UVB radiation on the backs of brown guinea pigs weighing approximately 450~500 g. Thirty ${\mu}l$ of ADWE, at each application, were applied twice a day, 5 days a week, for 8 weeks to the guinea pigs. The artificial tanning spots were divided into 3 groups which were vehicle control group [propylene glycol: ethanol: water (5:3:2)], positive control group (2% hydroquinone) and experimental group (2% ADWE). The visible whitening effect and changes in melanin index were evaluated once a week. On completion of the experiment, the animals were sacrificed under anesthetization, and the artificial tanning spots were excised by biopsy punch and stained with Hematoxylin and Eosin (H&E) to observe histological change and also stained with Fontana-Masson's silver (F-M) and S-100 to observe melanin pigmentation and melanocytes. In the gross observation, the experimental group showed higher pigmentation than the positive control group but lower pigmentation than the vehicle control group. Histological observation confirmed that ADWE had a positive whitening effect by showing a lower distribution of melanin and melanocytes in the epidermis of experimental group than in the vehicle control group.

Objectives: Angelicae Dahuricae Radix (Baek-Ji in Korean, BJ) is well known to be used as a medicine for cold, headache, supraorbital pain, nasal congestion, and toothache. Little is understood about the roles of BJ in the cytokine and chemokine secretion by immune cells. This study was designed to find out the effects of BJ on the cytokine and chemokine secretion in human mast cells (HMC). Methods : We treated BJ according to consistency on HMC and measured cytokines and chemokines levels using flow cytometry CBA system. Results: In BJ treated group. the expression of interferon-inducible protein 10 (IP-l0), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X-C motif) ligand 9 (MIG), and interleukin 10 (IL-l0) levels were decreased significantly and chemokine (C-C motif) ligand 5 (RANTES), IL-8, $interferone-{\gamma}$ ($IFN-{\gamma}$), and tumor necrosis factor alpha (TNF-a) were decreased significantly. Conclusion : The results of this experiment supposed that the treatment of BJ will ameliorate the secreting levels of some chemokines or cytokines such as IP-10, MCP-1, MIG, IL-10, RANTES, IL-8, $IFN-{\gamma}$, and TNF-a.

Objectives: The object of this study was to observe the in vitro anti-bacterial and anti-inflammatory effects of three single aqueous herbal extracts(Trichosanthes Semen, Gardeniae Fructus, and Angelicae Dahuricae Radix), traditionally used for treating various gynecological diseases including mastitis in Korea, against Staphylococcus aureus and lipopolysaccharide(LPS)-activated Raw 264.7 cells. Methods: Anti-bacterial activities of three single aqueous herbal extracts against S. aureus were detected using standard agar microdilution methods. In addition, the effects on the cell viability, $PGE_2$, NO, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 productions of LPS activated Raw 264.7 cells. The anti-bacterial and anti-inflammatory effects were compared with lincomycin and piroxicam, respectively in the present study. Results: MIC of three single aqueous herbal extracts against S. aureus were detected as over 25, $4.063{\pm}2.096$ and $1.641{\pm}0.972$ mg/ml, respectively. MIC of lincomycin was detected as $0.469{\pm}0.297{\mu}g/ml$ at same conditions. In addition, $ED_{50}$ against LPS-induced cell viabilities and cytokine releases of three single aqueous herbal extracts were as follows - cell viability: 7.635, 13.761, 6.986 mg/ml, NO production : 4.808, 22.015, 2.949 mg/ml, $PGE_2$ production : 3.040, 4.312, 0.821 mg/ml, TNF-${\alpha}$ production : 9.563, 54.931, 1.240 mg/ml, IL-$1{\beta}$ production : 1.362, 1.801, 0.534 mg/ml, IL-6 production : 0.371, 0.797, 0.202 mg/ml, respectively. $ED_{50}$ of piroxicam against LPS-induced cell viabilities, NO, $PGE_2$, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 were detected as 35.179, 6.552, 1.162, 7.273, 7.101 and 5.044 ${\mu}g/ml$, respectively at same conditions. Conclusions: The results of the study showed anti-bacterial effects against S. aureus in the order of Gardeniae Fructus and Angelicae Dahuricae Radix aqueous extracts, except for Trichosanthes Semen. They also showed anti-inflammatory effects against LPS-activated Raw 264.7 cells in the order of Angelicae Dahuricae Radix, Trichosanthes Semen, and Gardeniae Fructus aqueous extracts. These three herbs are expected to be great substitutes to reduce side-effect of lincomycin and piroxicam, if the amount of those three single aqueous herbal extracts is adjusted appropriately.

Objectives: The aim of this study was to investigate deodorizing effectsof medicinal herbs (Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex, Angelicae Dahuricae Radix) for development of a gargle solution. Methods: 1. The antimicrobial effects of medicinal herbs were evaluated with the minimal bactericidal concentration (MBC) and the change of the number of viable cells in the herb extracts(1%) for 48 hrs against P. gingivalis 2561 and Pr. intermedia ATCC 25611. 2. Deodorizing activity of each herb and Garglin $Mint^{(R)}$gainst methyl mercaptan were analyzed by gas chromatography (GC). 3. We used the malodor modeling of the salivary sediment system with a Halimeter. 4. In the preliminary clinical study, the baseline concentration of VSC in the oral cavity of each subject was measured by Halimeter. Subjects would gargle for 30 seconds with cysteine. After 4 minutes subjects would gargle for 30 seconds with Garglin and herb extracts (2%). Subsequently, concentration of VSC were measured at 0, 4, 8, 12 and 20 minutes. Results: 1. MBC of Mume Fructusfor P. gingivalis 2561 was determined to be <1% and MBCs of Eriobotryae Folium for P. gingivalis 2561 and Pr. intermedia ATCC 25611 were determined to be <2% and <1%, respectively. Mume Fructus (1%) completely suppressed the P. gingivalis cell viability from 5 hrs and Eriobotryae Folium (1%) completely suppressed the Pr. intermedia cell viability from 48 hrs. 2. In GC analysis, deodorizing activities were 91.54% with Mume Fructus, 87.97% with Eriobotryae Folium, 100% with Acanthopanacis Cortex, 72.36% with Angelicae Dahuricae Radix and 40.54% with Garglin $Mint^{(R)}$. 3. In malodor modeling of the salivary sediment system, each of the medicinal herbs had significantly inhibitory effect on malodor formation (p<0.05). 4. In the preliminary clinical study, the concentration of VSC of the herb groups was significantly lower than of the control group, but not in Garglin $Mint^{(R)}$. Conclusions: Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex and Angelicae Dahuricae Radixhave deodorizing activities and potential as an effective mouthwash against oral malodor.

Byakangelicin, 9-(2,3-dihydroxy-2-methylbutoxy)-4-methoxy-7H- furo[3,2-g][l]benzopyran-7-one (BKG), a component of Angelicae dahuricae Radix, is considered to be an inhibitor of aldose reductase for the treatment of diabetic cataract. An analytical method for the isolation of BKG developed by high-performance liquid chromatography has been reported. No literature on the metabolism of BKG, however, has been found. With the purpose of identifying new metabolites of BKG, BKG (100 mg/kg) was orally administered to Sprague-Dawley rats via a gavage. Using a metabolic cage, urine was collected for 24 h, and the urine samples were extracted by liquid-liquid extraction. For structural identification of new urinary metabolites of BKG, various instrumental analyses were conducted by gas-chromatography/mass spectrometry, high-performance liquid chromatography/diode array detector, liquid chromatography/mass spectroscopy with thermospray interface and $^1H$ nuclear magnetic resonance spectroscopy. Two metabolites produced from the Ο-demethylation or Ο-dealkylation of BKG were newly identified, and another new but unknown metabolite was assumed to be the hydroxylated form of BKG. These results indicate that the major metabolic products of BKG are formed by Ο-demethylation or Ο-dealkylation of BKG side chains.
