In this study, we screened twenty four extracts of eight medicinal plants and three extracts of the commercial product for their antimicrobial and antioxidant properties. Ethanol and ethyl acetate extracts were found active where as aqueous extracts were little or no active. Extracts of Sophora flavescens, Salvia miltlorrhiza and Glycyrrhiza uralensis showed strong activity againsttested organisms and could be the potential antimicrobial agent. The increase of antimicrobial and antioxidant activities of formulations might be due to synergic effect. The results also indicated that the activity of bamboo salt and herbal products can be enhanced by making appropriate formulations.

The development of microbial inoculant was conducted using a by-product of oriental herbal medicine. The constituent of the by-product, which was high in organic matter, was 11.3% of crude protein, 5.1% of crude lipid, 49.7% of NDF (neutral detergent fiber), and 33.8% of ADF (acid detergent fiber). Microorganisms isolated from the by-product of oriental herbal medicine were 35 species. Among them, 6 bacterial species, 4 fungal species, 2 actnomycetes species, and 1 yeast species were effective in the utilization of the by-products. The 13 strains screened were tested for the plant growth-promoting effect in soybean seedling. BL-333 strain was found to increase the soybean yield by about 23% as compared with control. The strain BL-333 was identified as Paenibacillus marcerans. P. marcerans BL-333 showed high anti-fungal activities against virulent fungi, especially Fusarium sp. and Collectotrichum sp. Yields of plants which were inoculated with microbial inoculant prepared with P. marcerans BL-333 and by-product of oriental herbal medicine were found to be higher than control by $3{\sim}24%$. The yield was especially promoted in lettuce, radish, chinese cabbage and cucumber plants.

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.

Objectives : The purpose of this study is to confirm the moisturizing effects of Herbal cosmetics containing Sinhyotakrisan(SHTL) extracts on facial skin.Methods : A total of 23 women who visited Semyung Oriental Medical Center from January 10th, 2014 to Feburary 12th, 2014 were included in the study. Provided both cosmetics containing Sinhyotakrisan extract and control products, all the subjects applied one of them to half face and another to remaining half for 4 weeks. We observed change of skin hydration, skin elasticity, skin scale in 0 week, 2 weeks, and 4weeks. Statistical anyalysis was performed by using SPSS, and statistical significance was achieved if the proability was less than 5%(p<0.05).Results : 1. After 4 weeks of using SHTL, skin hydration showed a statistically significant increase compared with using control product(p=0.011). And improvement rate also did(p=0.031). 2. After 4 weeks of using SHTL, skin elasticity showed statistically significant increase compared with using control product(p=0.025). But improvement rate didn't showed statistically significant increase(p=0.068). 3. After 4 weeks of using SHTL, skin scale showed a statistically significant decrease compared with using control product(p=0.029).

Objectives : Aucklandiae Radix (Muxiang) one of important herbal medicines in oriental medicine, is defined as the dried root of Aucklandia lappa (Asteraceae). Owing to the similarities in the morphology and name, Inulae Radix (Tu-Muxiang) and Vladimiriae Radix (Chuan-Muxiang) as well as Aristolochiae Radix (Qing-Muxiang) originated from other medicinal plants are often used as substitutes and/or adulterants of Aucklandiae Radix. Therefore, a reliable authentication of these herbal medicines is necessarily for the public health and prevention of misuse. Methods : 32 samples of medicinal plants supplying Aucklandiae Radix, Inulae Radix, Vladimiriae Radix, and Aristolochiae Radix were collected in Korea and China. The ITS (Internal transcribed spacer) nucleotide sequences of samples were determined. The PCR primers to amply DNA marker of each herbal medicine were designed basing on the specific ITS regions showing differences in the sequences among medicinal plants. Results : Primer set Al R/IS F designed in this work amplified 220 bp PCR product only in samples of Aucklandiae Radix. In contrast, primer set Ih F/IS R, Vs R/IS F, and AcR F1/Ac R amplified 250 bp product, 356 bp prouct, and 516 bp product respectively to identify Inulae Radix, Vladimiriae Radix, and Aristolochiae Radix. Conclusions : The primers designed basing on the nucleotide sequences of ITS regions appearing differenced in the sequences among medicinal plants amplified the DNA markers for the identification of Aucklandiae Radix, Inulae Radix, Vladimiriae Radix, and Aristolochiae Radix. These herbal medicines were more efficiently identified by multiplex PCR method using all primers in a single PCR process.

[6]-Gingerol is known as the major bioactive constituent of ginger. In the study, it was observed to effectively protect against ${\bullet}OH$-induced DNA damage ($IC_{50}$ $328.60{\pm}24.41{\mu}M$). Antioxidant assays indicated that [6]-gingerol could efficiently scavenge various free radicals, including ${\bullet}OH$ radical ($IC_{50}$ $70.39{\pm}1.23{\mu}M$), ${\bullet}O_2{^-}$ radical ($IC_{50}$ $228.40{\pm}9.20{\mu}M$), $DPPH{\bullet}$radical ($IC_{50}$ $27.35{\pm}1.44{\mu}M$), and $ABTS{^+}{\bullet}$radical ($IC_{50}$ $2.53{\pm}0.070{\mu}M$), and reduce $Cu^{2+}$ ion ($IC_{50}$ $11.97{\pm}0.68{\mu}M$). In order to investigate the possible mechanism, the reaction product of [6]-gingerol and $DPPH{\bullet}$ radical was further measured using HPLC combined mass spectrometry. The product showed a molecular ion peak at m/z 316 $[M+Na]^+$, and diagnostic fragment loss (m/z 28) for quinone. On this basis, it can be concluded that: (i) [6]-gingerol can effectively protect against ${\bullet}OH$-induced DNA damage; (ii) a possible mechanism for [6]-gingerol to protect against oxidative damage is ${\bullet}OH$ radical scavenging; (iii) [6]-gingerol scavenges ${\bullet}OH$ radical through hydrogen atom ($H{\bullet}$) transfer (HAT) and sequential electron (e) proton transfer (SEPT) mechanisms; and (iv) both mechanisms make [6]-gingerol be oxidized to semi-quinone or quinone forms.
