Objectives : We carry out the simultaneous quantification for quality control of four components in Bangpungtongseong-san (BPTSS) sample. In addition, we assessed the antioxidant effects of BPTSS sample. Methods : The used column for separation and analysis of four compounds was Luna C18 column and column oven temperature was maintained at $40^{\circ}C$. The mobile phase for simultaneous determination consisted of two solvent systems, 1.0% acetic acid in water and 1.0% acetic acid in acetonitrile. High performance liquid chromatography-photodiode array (HPLC-PDA) method for analysis was performed at a flow rate of 1.0 mL/min with PDA detection at 254 and 280 nm. The injection volume was 10 ${\mu}L$. The antioxidant activities of BPTSS were evaluated by measuring free radical scavenging activities on 2,2'-Azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) and 1-1-diphenyl-2-picrylhydrazyl (DPPH). The inhibitory effects on low-density lipoprotein (LDL) oxidation were evaluated by the formation of thiobarbituric acid relative substances (TBARS) and relative electrophoretic mobility (REM). Results : Calibration curves were acquired with $r^2{\geq}0.9999$. The values of limit of detection (LOD) and quantification (LOQ) were 0.06-0.29 ${\mu}g/mL$ and 0.20-0.98 ${\mu}g/mL$, respectively. The amounts of geniposide, liquiritin, baicalin, and glycyrrhizin in BPTSS were 5.06, 7.33, 27.56, and 7.81 mg/g, respectively. The BPTSS showed the radical scavenging activity in a dose-dependent manner. The concentration required for 50% reduction (RC50) against ABTS and DPPH radicals were 72.51 ${\mu}g/mL$ and 128.49 ${\mu}g/mL$. Furthermore, GMGHT reduced the oxidation properties of LDL induced by CuSO4. Conclusions : The established HPLC-PDA method will be helpful to improve quality control of BPTSS. In addition, BPTSS has potentials as therapeutic agent on anti-atherosclerosis.

Objectives We studied long-term preservation in stability of a mixed preparation of distilled and 70% alcohol extracted Hwangnyunhaedok-tang pharmacopuncture to establish standards for expiration date and quality control. Methods Three lots of consecutively prepared Hwangnyunhaedok-tang pharmacopuncture were each tested in triplicate to a total 5 tests at 3 month intervals over a period of 12 months for analysis of appearance, pH, specific gravity, index component content, endotoxins, microbial sterility, residual organic solvents, heavy metals, and pesticides. Items with no difference by elapsed time were tested at the initial and final timepoints, and data of items with potential difference by elapsed time were analyzed for trends to establish individual quality control standards. Results All tested items were stable over the study period, and therefore the expiration date was set as 12 months. pH quality control standards were set as 3.66~5.69, and that of specific gravity as 0.802~1.203, respectively. In index component content standards, berberine was set at $4.96{\sim}8.98{\mu}g/vial$, baicalin at $6.47{\sim}10.31{\mu}g/vial$, and geniposide at $116.03{\sim}189.55{\mu}g/vial$, respectively. Standards for other items with no difference by elapsed time were set according to general Korean herbal medicine standards in the Korean Pharmacopoeia. Conclusions Manageable expiration date and quality control standards were established through long-term preservation testing of Hwangnyunhaedok-tang pharmacopuncture, furthering standardization of Korean medicine pharmacopuncture.

Hwangryunhaedok-tang (HRT) is a traditional herbal medicine, which has been known as a useful prescription for anti-biotic, anti-inflammatory, anti-oxidative and immunosuppressive activity. In this study, the variation in the amount of eight bioactive components of Hwangryunhaedok-tang (HRT) and its fermentation HRT with Lactobacillus casei KFRI 127, Lactobacillus curvatus KFRI 166 and Lactobacillus confuses KFRI 227 was investigated via high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of eight bioactive components; geniposide, genipin, baicalin, wogonoside, palmatine, berberine, baicalein and wogonin was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. All calibration curve of standard components showed good linearity ($r^2$ >0.979). As a result, the geniposide amount was $15.52{\pm}0.19{\mu}/mg$ that as a main components in HRT. The wogonoside was decreased by 29.28~58.35% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($3.17{\pm}0.31{\mu}g/mg$ and $3.55{\pm}0.13{\mu}g/mg$) compared with the original HRT ($5.02{\pm}0.14{\mu}g/mg$). Otherwise wogonin was increased by 16.28~41.86% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($0.61{\pm}0.01{\mu}g/mg$ and $0.50{\pm}0.02{\mu}g/mg$) compared with the original HRT($0.43{\pm}0.00{\mu}g/mg$). HRT fermented with L. casei KFRI 127 and L. confuses KFRI 227 were evaluated as creating the changes in wogonoside to that aglycon wogonine. In the fermented HRT using Lactobacillus acidophilus KFRI 166, the genipin was only detected, among 3 species of fermentation strains. Thus, these results considered that the strains 166 were exhibited the remarkable changes in genipin.

Objectives : The biological activities and compound contents of herbal medicine vary depending on manufacturing processes. In this study, we compared anti-inflammatory effects and compound contents of three kinds of multi-herbal extract HT008 produced by different manufacturing processes in order to determine chemical and biological equivalence. Methods : HT008 was produced by three different manufacturing methods: 1. Freeze dried extract of Eleutherococcus senticosus, Scutellaria baicalensis and Angelica sinensis (HT008 FD), 2. Spray dried extract of E. senticosus and S. baicalensis combined with reflux extract of A. sinensis (HT008 SD), 3. Spray dried extract of E. senticosus and S. baicalensis combined with supercritial fluid extract of A. sinensis (HT008 SF). Anti-inflammatory effects were evaluated using acetic acid induced pain model and ${\lambda}$-carageenan induced paw edema model. Compound contents were evaluated by HPLC quantitative analysis of standard compounds of HT008, eleutheroside E, baicalin, z-ligustilide. Results : HT008 FD, HT008 SD and HT008 SF significantly decreased acetic acid induced pain index and ${\lambda}$-carrageenan induced paw edema volume compared with that of control group. There was no significant difference in efficacy among the HT008 FD, HT008 SD and HT008 SF. Standard compound contents of HT008 FD, HT008 SD and HT008 SF were quantified within the range of Korean pharmacopoeia or other research. Conclusions : Three different manufacturing methods of multi-herbal extracts have been developed without noticeable difference in the efficacy or compound contents. The results might be used to establish manufacturing process and industrialization of herbal extracts.

Scutellaria radix (SR) has been utilized as a traditional medicine for a variety of diseases including Rheumatoid arthritis and its major flavonoids - baicalein, baicalin, and wogonin - have been reported to exert beneficial health effects, including anti-bacterial, anti-viral, anti-inflammatory, and free-radical scavenging. However, the mechanisms underlying this effect remain poorly understood. The principal objective of this study was to determine the effect of SR on osteoblast and osteoclast cells. SR extract was prepared using 70% ethanol solvent. Osteoblastic MC3T3-E1 cells and osteoclast precursor Raw 264.7 macrophage cells were utilized. SR extract increased MC3T3-E1 cell proliferation and stimulated alkaline phosphatase activity dose-dependently, 152.0% of the control at concentration $1{\mu}g/mL$. Additionally, SR extract ($1{\mu}g/mL$) stimulated Bone nodule formation activity in MC3T3-E1 cells, approximately 223.3% of the control, 20 days after the exposure. In addition, SR extract significantly reduced the number of tartrate-resistant acid phosphatase-positive (TRAP+) multinucleated cells from Raw 264.7 cells. In conclusion, SR extract stimulates the proliferation and bioactivities of boneforming osteoblasts, and inhibits the activities of bone-resorbing osteoclasts to a certain degree.
