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.

황금 추출물이 조골세포와 파골세포에 미치는 영향을 세포수준에서 관찰하고자 하였다. 조골세포에 미치는 영향을 관찰하기 위하여, mouse calvaria 유래의 MC3T3-E1 osteoblastic cells를 이용하여 세포 생존률, 염기성 인산분해효소 활성, 골석회화 형성능을 측정하였다. 또한 미분화된 파골세포 전구세포로부터 파골세포의 생성 및 활성에 미치는 영향을 관찰하기 위하여, murine macrophage 유래인 Raw 264.7 cells를 이용하여 M-CSF와 RANKL을 처리하여 파골세포의 분화를 유도하였고, TRAP에 양성인 다핵세포의 형성을 관찰하여 황금추출물이 파골세포의 형성에 미치는 영향을 알아보았다. 황금 추출물이 MC3T3-E1 세포의 증식에 미치는 영향을 MTT assay로 측정한 결과, MC3T3-E1 세포는 처리한 황금 추출물의 농도에 의존적으로 세포의 증식이 촉진되는 경향을 나타내었으며 특히 $1{\mu}g/mL$ 농도에서 130.4%의 증식 효과를 나타내었다. 또한 황금 추출물이 세포에 독성을 나타내지 않는 범위($0.01-1{\mu}g/mL$)에서 MC3T3-E1 세포의 ALP activity를 측정한 결과, 농도에 의존적으로 ALP activity가 증가하였으며 $1{\mu}g/mL$ 농도에서 152.0%의 ALP 활성 증가효과를 나타내었다. 황금 추출물의 최적 작용 농도 $1{\mu}g/mL$에서 골석회화 형성능을 측정한 결과, 배양 시간에 따라 계속 증가하여 배양 20일째는 대조군에 비해 223.3%의 석회화 형성능을 나타내었다. 황금 추출물의 파골세포 분화억제 효과를 알아보기 위해 황금 추출물이 세포에 독성을 나타내지 않는 범위($0.01-10{\mu}g/mL$)에서 TRAP staining한 결과, 황금 추출물은 $0.0{1\mu}g/mL$ 농도에서 대조군에 비해 파골세포 분화를 50% 이상 감소시켰으며 농도 의존적으로 TRAP 양성 세포가 감소함을 관찰하였다. 이상의 결과로 미루어 볼 때, 황금 추출물이 골다공증을 포함한 골질환 예방에 효과가 있을 것으로 사료된다.
