Background: The extract of Abies holophylla is used as an ingredient in cosmetics. This study assessed the antioxidant and antibacterial activities of the material remaining after the extract is used. Methods and Results: The 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azinobis (3-ethyl benzothiazoline)-6-sulfonic acid (ABTS) radical scavenging abilities were assessed to determined the free radical scavenging activity. The total phenol and flavonoid contents were determined to measure the antioxidant activity. The DPPH and ABTS radical scavenging activities of the resudual extract were higher (95.61 - 99.42% and 74.26 - 77.98% in water extract respectively) than those of the positive control. In 50% EtOH extract, the total phenol content was $389.84mg{\cdot}GAE/m{\ell}$, and the total flavonoid was $0.15mg{\cdot}QE/m{\ell}$. The minimum inhibition concentration degree for antibacterial activity against Staphylococcus aureus was < 8 to < $125{\mu}g/m{\ell}$ compared to that of the positive control in all extracts. The clear zone against S. aureus was found to be $12.2{\pm}3.8mm$. Conclusions: The A. holophylla byproducts were found to have antioxidant and antibacterial activities. Therefore, the materials remaining after the A. holophylla extract is used in cosmetics has potential functional uses.

Objectives : Since single extract powders was released at 1987, the insurance fee has not been changed, but the price of raw material has been increasing. According to this, Pharmaceutical company couldn't invest on quality of the product, so, the quality of single extracts went down and lost the consumer's trust. We checked the contents of marker ingredients in single extract thereby to recover the reliability of insurance-covered herbal preparations. Methods : we bought total twelve products of eight different single extracts of two main pharmaceutical companies among total 65 kinds of single extract powder stipulated in KHP (The Korean Herbal Pharmacopoeia) monograph III at Jan. 2013. Assays of selected single extract powders are performed by KHP regulation. And we surveyed price fluctuation of relevant herb raw materials from 2005 to 2012. Results : Among twelve products, eight single extract powders were suitable by the KHP regulation. But four products didn't reach the content amount of KHP. Marker contents in the single extracts product of Pueraria Root, Licorice, Peony root and Scutellaria Root of A company were 70%, 1%, 23.7% and 75.1%, respectively. Conclusions : We can acertain whether there's a quality problem in the insurance-covered single extract powders. But, A company is no longer producing these improper single extract powders. As a medicine, single extract powders needs to be strictly quality controlled by the company, and regularly monitored by the KFDA.

Obesity has become one of the main public health problems. Saussurea lappa (Asteraceae), syn Aucklandia lappa and Saussurea costus, is a well-known herbal medicine that has been used for treating various ailments, such as inflammatory and gastrointestinal diseases. The present study examined the anti-obesity effect of S. lappa extract (SLE) in 3T3-L1 adipocytes and high fat diet (HFD)-induced obese mouse model. SLE significantly inhibited the differentiation from preadipocytes to adipocytes of cultured 3T3-L1 in dose-dependent manner. In addition, SLE significantly decreased the body weight gain and the food efficiency ratio of mice fed HFD during 9 weeks. Further study must be performed for the pharmacological mechanism and safety of SLE as well as the identification of active compound in SLE. Our results revealed that S. lappa suppresses the adipogenesis in cultured cells and the obesity in rodent models. Therefore, S. lappa may be useful toward the development of new potent anti-obesity drugs.

Achyrantes japonica (AJ) has been used to treat edema and arthritis in the traditional Korean medicine. To elucidate the anti-inflammatory and anti-nociceptive effects of ethanol extract of AJ, the carrageenan-induced paw edema using a plethysmometer and thermal hypersensitivity using the plantar test were measured. Ibuprofen was used as a control drug. Treatment with AJ (200mg/kg p.o.) significantly reduced paw edema, compared to the carrageenan - treated rats. In the plantar test, the thermal withdrawal latency in AJ - treated group was significantly increased than the carrageenan - treated group. The results indicate that AJ could have be the anti-inflammatory and anti-nociceptive properties.

Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine, in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailavility and pharmacological activity of herbal extract in the gastrointestinal tract. It also produces a number of fermentation products that intensify the nutritional and pharmacological aspects of the medicinal herbs. In order to develop a functional beverage of alleviating the aftereffects of the previous drinks, the extracts (HP-1) of fermented herbal mixture, including Artemisia capillaris Thunb., Lonicera japonica Thunberg, and Hovenia dulcis Thunb., were prepared and the medicinal effect as a hangover cure was evaluated in ethanol-loaded rats. The enzyme activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase-2 (ALDH2) were analyzed by measuring the concentration of blood ethanol and acetaldehyde. The mRNA expression of ADH and ALDH2 was also investigated through RT-PCR analysis. In the HP-1-treated group, the concentration of blood ethanol was significantly reduced at one hour after loading of ethanol, as compared to that in the saline-treated group. The reduced ethanol was converted to acetaldehyde, which resulted in rapid increase in acetaldehyde concentration in an hour. Acetaldehyde was started to decrease at 5 hours after ethanol loading. It implies that HP-1 is highly effective to stimulate the activities of ADH and ALDH2. The HP-1 treatment also activated the mRNA expression of ADH and ALDH. This study suggests that fermented herbal extract, HP-1 can be used as a functional beverage of alleviating the alcohol-induced hangover symptoms by stimulating the activities and gene expression of hepatic alcohol metabolizing enzymes.

Objectives : The purpose of this study was to evaluate boiled rice made from unpolished rice, Job's Tears, and extract from medicinal herbs mixture (HGMCJE) for hypoglycemic effect on STZ-induced diabetic rats. Methods : In the response of glucose tolerance, control and diabetic rats groups was intubated with glucose and HGMCJE. Furthermore, boiled 100% polished rice (P rice), boiled unpolished rice mixed with white rice and Job's tears (polished rice:unpolished rice:Job's tears=60:25:15, UPJ-rice), and UPJ rice made from HGMCJE (HUPJ-rice) were intubated to control and diabetic rats groups, respectively. Then, blood glucose concentration, incremental blood glucose, and area under the curve (${\Delta}AUC$) were analyzed in every experimental groups, and these data were used to evaluate glycemic response. Results : When glucose and p rice were intubated in control and diabetic rats, blood glucose concentration, incremental blood glucose, and incremental response ${\Delta}AUC$ of diabetic groups were significantly increase than control groups. But administraion of a single dose of extract from medicinal herbs mixture and HUPJ-rice in control and diabetic rats inhibited the remarkable increase the level of postprandial blood and ${\Delta}AUC$ at 60, 90, and 120 min Conclusions : These results indicate that when intubation of glucose and P rice were out of control on postprandial glycemic response in diabetic rats. But postprandial glycemic response was well-modulated by administrating a single oral dose of HGMCJE and HUPJ-rice. Therefore, HGMCJE can be developed as an effective hypoglycemic agent.
