HPL-4 is a new herbal formulation developed for the treatment of osteoarthritis. In this study, we took HPL-4 to develop a method for simultaneous determination of nine marker compounds (protocatechuic acid, chlorogenic acid, liriodendrin, nodakenin, ${\beta}$-$\small{D}$-(3-O-sinapoyl)frucofuranosyl-${\alpha}$-$\small{D}$-(6-O-sinapoyl)glucopyranoside, quercitrin, 6-gingerol, decursin and decursinol angelate) present in the formulation. The analytes were separated by UPLC system consisting of diode array detector at 205 nm and RP-amide column, and solvent system of $ACN/0.1%H_3PO_4$. Analytical method was validated to evaluate its linearity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy. All standards showed good linearity ($R^2$ >0.99) in the rage of $0.25-400.0{\mu}g/mL$. The LOD and LOQ were within the range of 0.021-0.148 and $0.070-0.448{\mu}g/mL$, respectively. Intra- and inter-day precision was less than RSD 4.0% and the accuracy was range from 92.00-104.81% with RSD<4.2%. The results suggest that the developed UPLC method is precise, accurate and effective, and could be applied for quality control of HPL-4 formulation.

Objectives : The oriental medicine Jangwonhwan, a boiled extract of 12 medicinal herbs/mushrooms, has been prescribed to patients with cognitive dysfunction, as originally described in the Korean medical text, DonguiBogam(amnesia chapter). Recently, a modified formula of Jangwonhwan (LMK02-Jangwonhwan) consisting of seven medicinal plants/mushrooms, was shown to reduce the ${\beta}$-amyloid deposition in the brain of Tg-APPswe/PS1dE9 mouse model for Alzheimer's disease. The toxicity of LMK02-Jangwonhwan was investigated in SD rats, by a daily oral administration for 13 weeks and NOAEL(No observed adverse effect dose), a definite toxic dose and target organ, as well. Methods : Quality control of the tablet form of LMK02-Jangwonhwan was established by estimating the indicative components, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelicagigas Nakai. The toxicity of LMK02-Jangwonhwan was investigated in 6 week old, specific pathogen free (SPF), Sprageu-Dawley rats by oral administration. Each test group consisted of 10 male and 10 female rats. The groups received doses of 500, 1,000 or 2,000 mg/kg/day of test substance for 13 weeks. The clinical signs, death rate, body weight, food consumption, ophthalmic examination, urinalysis, hematological and serum biochemistry, organ weight and pathological changes were examined and compared with those of the control group. Results : The 13-week repeated oral treatment doses didn't result in any specific symptoms or death. There were no significant changes in the rat's weight and food consumption. Further, ophthalmic examination, urinalysis, hematological, serum biochemistry test and organ weight revealed no significant differences. Conclusions : The no-observed-adverse-effect level(NOAEL) of LMK02 for male and female Sprague-Dawley rats was determined as 2,000mg/kg/day and the target organ wasn't confirmed. Because no significant adverse effects were observed, the target organ could not be determined.

The effects of fermented products from 40 medicinal herbals commonly available in Korea were examined according to concentrations of polyphenolic compound and kojic acid, and the activities of DPPH ($\alpha,\alpha$'-diphenyl-$\beta$-picrylhydrazyl) free radical scavenging and tyrosinase. The polyphenolic compound concentrations were 0.24 by Corydalis turtschaminovill ~ 11.42% (dry matter basis) by Syringa velutina in the extracts and 0.18 by Poria cocos ~ 12.27% by S. velutina in the fermented products. Kojic acid concentrations were 0.02 by Poria cocos Sclerotium ~ 9.67 mM by S. velutina in the extracts and 0.33 by P. cocos ~ 10.32 mM by S. velutina in the fermented products. Syringa velutina contained the highest polyphenolic compound and kojic acid concentrations, which were higher in the fermented product than in the extract. Higher DPPH free radical scavenging activity (>60%) was observed in the extracts of A. sessiliflorum, Citrus nobillis, and Angelica gigas and the fermented product of A. sessiliflorum compared to the other medicinal plants. Higher tyrosinase inhibition activity (>50%) was observed in the extracts of Morus alba, Glycyrrhiza glabra, and Rubus coreanus and the fermented products of G. glabra, Cnidium officinale, and S. velutina. Based on the above results, G. glabra, C. officinale, and S. velutina possessed high tyrosinase-inhibitive activities and kojic acid concentrations, which could be definitely enhanced by the fermentation of Phenillus linteus mycelium.

Objectives To check marker content for appropriate quality control of Woohwangchungsimwon sterilized to ensure microbiological safety and to observe antioxidant activity for any changes in efficacy. Methods To measure any effects of sterilization on the effective compounds, 8 ingredients of Woohwangchungsimwon were screened for any changes in marker content using HPLC-DAD. Using the colorimetric method on the microplate reader any changes in total phenolic compound and flavonoid levels were observed. Antioxidant activity was measured using the DPPH, ABTS, and FRAP. Results Of the ingredients of Woohwangchungsimwon, 8 were subject to quantitative analysis before and after sterilization. 21.6 mg and 1.93 mg of Glycyrrhizin was found in Glycyrrhiza uralensis Fischer pre and post sterilization, respectively. Decursin found in Angelica gigas Nakai increased from 0.16 mg to 0.29 mg after sterilization. Bilirubin found in Gallstone of Bostaurusvar. domesticus increased from 0.24 mg to 0.33 mg. Cinnamic acid found in Cinnamomum cassia Blume increased from 0.02 mg to 0.05 mg. Ginsenoside Rb1 found in Panax ginseng C. A. Meyer decreased from 0.02 mg to 0.14 mg. Paeoniflorin found in Paeonia lactiflora Pallas increased from 1.05 mg to 1.13 mg. Amygdalin found in Armeniacae Amarum Semen increased from 2.68 mg to 2.83 mg. L-muscone found in Musk increased from 0.63 mg to 0.76 mg. As for total phenolic compound and total flavonoid content, there was a 1.22 and 4.15-fold increase. DPPH and ABTS increased by 20.45% and 20.69%, respectively. FRAP activity was 2.78 times more active post stabilization. Conclusions This study confirmed that high temperature high pressure steam sterilization, a method used to ensure microbiological safety of Woohwangchungsimwon, does not affect marker content; in other words, does not affect quality of the Woohwangchungsimwon. It could also be seen that total phenolic compound and flavonoid content increased after sterilization. An antioxidant activity test showed that there was significantly increased activity of antioxidants.

This research was performed to develop a new material consisting of a mixture of Red Allium cepa (RA) Cucurbita moschata duch (CM), and Angelica gigas Nakai (AG). RA and CM have low storage stability because of their high moisture content. Therefore, their major components were extracted and used for the research after a content analysis. In order to overcome these limitations, the quercetin from RA, ${\beta}-carotene$ from CM, and decursin/decursinol angelate (D/DA) from AG were separately extracted, and the biochemical activity of each extract and mixture was compared. RA was bioconverted by the Bacillus subtillis KJ-3 (BS3) after ethanol extraction. After bioconversion, the quercetin content of RA was increased by 128.9%. ${\beta}-carotene$ was detected in the CM ethanol extract and its content was very low concentrations at 0.2 mg/g. The AG ethanol extract (1 mg) contained 0.4146 mg and 0.3659 mg of D/DA, respectively. The purity of the D/DA was found to be about 78%. The flavonoid and polyphenol content of each extract and their mixtures (mixture 1 (RA:CM:AG = 5:2:3), mixture 2 (RA:CM: AG = 3:5:2), and mixture 3 (RA:CM:AG = 3:2:5)) were measured. In addition, the cell survival rate, anti-inflammatory activity, and antioxidant ability were also evaluated. In all the results, the antioxidant activity of mixture 3 was most effective. Therefore, these findings provide basic data for future food development using a 3:2:5 mixture of RA, CM, and AG.
