Korean medicinal herbs -sasam, gilkyung, jakyak, danggwi, hwangki and chunkung were soaked to the distillate of Korean rice wine for 75 days. The alcohol concentration of distillate, soaking media was adjusted to 45, 35, and 25% respectively with distilled water. Changes in alcohol concentration, pH, optical density, concentration of peoniflorin and decursin were analyzed. Quality of the final product was determined by sensory evaluation. Alcohol concentration was rapidly decreased but pH increased in 15 days and thereafter they showed slow decrease. Decrease of alcohol concentration was affected by the kind of herb and alcohol concentration of soaking media. The strongest effect was observed from danggwi and low alcohol concentration. Concentration of paeoniflorin and decursin, an index component of jakyak and danggwi respectively, showed the similar trend of decrease after increase to maximum concentration. From the sensory evaluation, the best overall quality was obtained from liquors made from 45% alcohol concentration. The quality was decreased in the order of sasam, jakyak, chunkung and hwanggi.

Antimicrobial activity of Jakyak(Paeonia japonica var. pilosa $N_{AKAI}$) was investigated. Methanol extract of dried Jakyak was fractionated to hexane, chloroform, ethylacetate, butanol and aqueous fraction. Ethylacetate fraction among these fractions showed the highest inhibitory effect on the microorganisms such as B. subtilis, L. monocytogenes, and V. parahaemolyticus at 500 $\mu\textrm{g}$/disc. Ethylacetate fraction was further fractionated into 11 fractions by silica gel column and thin layer chromatography(TLC). The results showed that ethylacetate fractions No. 3, 4 and 5 had the highest antimicrobial activity. They were mixed again, re-separated, and 5 fractions were obtained. Among them, the highest inhibitory effect was obtained in No. 3 fraction, which was identified as cetyl alcohol by HPLC and GC-MS.S.

Objectives: In this study, we investigated the oral toxicity of Gami-Jakyak Gamcho buja Decoction (Mecasin) to develop safe treatments. Methods: All experiments were conducted at the Medvill, an institution authorized to perform non-clinical studies, under the Good Laboratory Practice (GLP) regulations. In order to investigate the oral toxicity of Mecasin, we administered Mecasin orally to rats. Sprague-Dawley rats were divided into four groups of five male and five female animals per group: group 1 being the control group and groups 2, 3, and 4 being the experimental groups. Doses of Mecasin, 500 mg/kg, 1,000 mg/kg and 2,000 mg/kg, were administered to the experimental groups, and a dose of normal saline solution, 10 mL/kg, was administered to the control group. We examined the survival rate, weight, clinical signs, and gross findings. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: No deaths or abnormalities occurred in any of the four groups. Although slight decreases in the weights of some female rats were noted on the third day, no significant changes in weights or gross findings between the control group and the experimental groups were observed. To check for abnormalities in organs, we used microscopy to examine representative histological sections of each specified organ; the results showed no significant differences in any of the organs. Conclusion: The results showed that administration of 500 - 2,000 mg/kg of Mecasin did not cause any changes in weight or in the results of necropsy examinations. It also did not result in any mortalities. The above findings suggest that treatment with Mecasin is relatively safe. Further studies on this subject are needed to yield more concrete evidence.

Korean general medicinal herbs-sasam, gilkyung, jakyak, danggwi, hwangki, and chunkung-were added In the normal brewing procedure as a raw material or in the distilling procedure as a packing material. The distillates from the former procedure and those from the latter procedure were compared in quality and distillation properties. As distillation proceeded, pH of the medicinal herb wine distillate and the control(not added herbs) distillates were decreased, whereas that of the herb packing distillate was increased slowely of $0.05{\sim}0.97$ during $1{\sim}4$ fractions and decreased remarkably of $0.92{\sim}0.98$ afterward. Average pH was the highest of 5.70 in jakyak and lowest of 4.37 In gilkyung. Absorbances of the herb Packing distillate were decreased rapidly of $0.60{\sim}1.59$ in the $1{\sim}4$ fractions but slowely of $0.19{\sim}0.54$ in the next fractions. During distillation both fractional alcohol concentration of the distillates and distillation rate were decreased. Their values were decreased more slowly than the control. Distillation rates of medicinal herb wine distillate were varied by medicinal herb varieties and alcohol concentration of fermented wine. Danggwi and control showed the highest average distillation rate as $0.12\;m{\ell}/sec$ and gilkyung the lowest value as $0.073\;m{\ell}/sec$. Maximum concentration of index component, paeoniflorin of jakyak was observed as 293 mg% in the 5th fraction of herb packing distillate and decrusin of danggwi as 3514 mg% In the 1st fraction of herb packing distillate. The extraction rate was 41.3% for paeoniflorin and 20.5% for decrusin. From sensory evaluation, the highest overall Qualify was observed in the medicinal herb wine distillate of hwangki added wine, the next in those of danggwi and jakyak added wine.

The pharmacological activities of paeoniflorin abtained from paeony roots, F$_M$100 from glycyrrhiza roots, crude saikosides from bupleurum roots, crude platycodin from platycodon roots, and bothj of ginsenoside Rb and ginsenoside Rg series from ginseng roots were investigated. Paeoniflorin, F$_M$ 100, crude saikosides, and crude platycodin exhibited sedative antipyretic, anlagesic and anti-ulcerative actions. In addition, crude saidosides and crude platycodin showed antitusaive and the potent anti-inflammatory action. An expectorant action was also observed with crude platycodin. These results coincided with the clinical applications of the aforementioned oriental medicinals. It also should be noted that crude saikosides nad crude platycodin are preferable to the other steroidal nad nonsteroidal drugs as an anti-inflammatory agent, because the drugs aggravate the digestive ulcer. In ginseng, G No3. and GNS frctions out of ginsenoside Rb series hsowed stimulant and antifatigue actions. The synergistic effects identified between paeoniflorin and F$_M$ 100 on the various pharmacological activities, have verified the reasonability of combined uses of two oriental drugs as Jakyak Gaqmcho-Tang.

Objectives: In this study, we investigated the 4-week repeated-dose oral toxicity of gami-jakyak gamcho buja decoction (Mecasin) to develop safe treatments. Methods: In order to investigate the 4-week oral toxicity of Mecasin, we administered Mecasin orally to rats. Sprague-Dawley (SD) rats were divided into four groups of five male and five female animals per group: group 1 being the control group and groups 2, 3, and 4 being the experimental groups. Doses of Mecasin of 500, 1,000, and 2,000 mg/kg of body weight were administered to the experimental groups, and a dose of normal saline solution of 10 mL/kg was administered to the control group. We examined the survival rate, weight, clinical signs, and gross findings for four weeks. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: No deaths occurred in any of the four groups. No significant changes in weights or food consumption between the control group and the experimental groups were observed. Serum biochemistry revealed that some groups showed significant decrease in inorganic phosphorus (IP) (P < 0.05). During necropsy on the rats, one abnormal macroscopic feature, a slight loss of fur, was observed in the mid dosage (1,000 mg/kg) male group. No abnormalities were observed in any other rats. In histopathological findings, the tubular basophilia and cast of the kidney and extramedullary hematopoiesis of the spleen were found. However, those changes were minimal and had occurred naturally or sporadically. No other organ abnormalities were observed. Conclusion: During this 4-week, repeated, oral toxicity test of Mecasin in SD rats, no toxicity changes due to Mecasin were observed in any of the male or the female rats in the high dosage group. Thus, we suggest that the doses in a 13-week, repeated test should be 0, 500, 1,000, and 2,000 mg/kg respectively.

Objectives : Jakyakgamcho decoction is a traditional prescription known to be an effective pain control medication and muscle relaxant. For more localized treatment outcomes achieved in a shorter period of time, Jakyakgamcho decoction was reprocessed into a form of pharmacopuncture. An analysis of Jakyakgamcho decoction pharmacopuncture showed that there was a significant loss of paeoniflorin(Jakyak's index component). This study was designed to investigate ways to minimize this loss. Methods : After making changes to the processing methods of Jakyakgamcho decoction pharmacopuncture, we measured the quantity of paeoniflorin using high performance liquid chromatography(HPLC) for a before-and-after analysis Results : Paeoniflorin loss was observed 15 minutes after sterilization with $Na_2HPO_4$ at $121^{\circ}C$ Conclusions : It was found that paeoniflorin loss did not occur when pH was not controlled for during processing.

MRSA is Staphylococcus aureus resistant to β-lactam antibiotics, and is a worldwide infectious disease. Even with the discovery of new antibiotics, resistance develops rapidly, so new alternatives are needed. Jakyakgamcho-tang (JGT) is a combination of Jakyak and Gamcho, and has been mainly used as an antispasmodic and analgesic in oriental medicine. This study was conducted to find out whether there is an effect on MRSA in relation to the anti-inflammatory effect of JGT and the antibacterial effect of Jakyak and Gamcho found in previous studies. In this study, in order to investigate the antibacterial activity of JGT and the combined effect of existing antibiotics, after extracting JGT with 70% EtoH, the disc diffusion method, minimum inhibitory concentration (MIC), drug combination effect (FICI), and time-kill analysis (Time-kill assay), metabolic inhibition, Western blot and qRT-PCR analysis were used to confirm the antibacterial activity mechanism of MRSA of JGT. As a result of the experiment, all of MRSA showed antibacterial activity in JGT's disc diffusion method, and the MIC was 250-1000 ㎍/mL. When existing antibiotics and JGT were combined with drugs, most had synergy or partial synergy. In addition, it was confirmed that the degree of bacterial growth was suppressed over time when simultaneous administration for 24 hours. JGT showed a synergistic effect when administered together with the ATPase-inhibitor DCCD, suggesting that it affected the inhibition of ATPase. As a result of observing the expression of PBP2a, and hla protein in the JGT-treated group and the untreated control group through wstern blot, it was confirmed that the protein expression of the JGT-treated group was significantly suppressed, and the expression levels of mecA, mecR1 and hla genes were also suppressed during JGT treatment. was observed by qRT-PCR. Combining the results of the experiment, it can be seen that JGT has antibacterial activity in MRSA, and when combined with existing antibiotics, the effect was increased compared to treatment with the drug alone. This suggests that JGT can be an alternative to treatment for antibiotic resistance of MRSA.
