Objectives : The fresh young leaves and dried fruits of Zanthoxylum piperitum (Korean name: Chopi) are used as diuretics, stomachies, anthelmintic and for the treatments of disorders of the digestive organ in Asia. We investigated inhibitory effects of Zanthoxylum piperitum extract on lipopolysaccharide(LPS)-induced production of nitric oxide(NO) and pro-inflammatory cytokines including $TNF-{\alpha}$ and $IL-1{\beta}$ from RAW264.7 mouse macrophage cells. Methods : After methanol extract of Zanthoxylum Fructus (Zanthoxylum extract) was pretreated in RAW264.7 cells, the cells were stimulated with LPS. Cell toxicity of Zanthoxylum extract was assayed bv MTT assay. The production of NO from the cells was measured in culture medium by Griess reaction. The production of $TNF-{\alpha}$ and $IL-1 \;{\beta}$ from the cells was measured in culture medium by ELISA. Results : Zanthoxylum Fructus extract greatly inhibited the production of inflammatory mediators such as NO, $TNF-{\alpha}$ and $IL-1{\beta}$ from LPS-stimulated RAW264.7 cells. Conclusion : This result suggests that Zanthoxylum extract may have an anti-inflammatory effect through the inhibition of inflammatory mediators.

Objectives : The purpose of this study is to determine the impurity tolerance of Zanthoxylum Peel. Methods : Compare with medicinal Herb Books and the Pharmacopoeia of 6 nations. Results : Current Pharmacopoeia show different Zanthoxylum Peel's Purity, such as 2.0% of seeds and fruit stalk, etc. in North Korea, 2% of seeds in Vietnam, totally 3% in China. On the other hand, Korea and Japan set the total number 26.0% including the specific numbers such as 20.0% of seeds, 5.0% of fruit stalk, 1.0% of the other foreign matter. This Zanthoxylum Peel's Purity, 26.0%, is too high compared to that of other medical matters specified by The Korean Pharmacopoeia Ninth Edition. When The Japanese Pharmacopoeia Sixth Edition firstly set the Zanthoxylum Peel's Purity, the herbal name was Fructus. However, since the part for medical usage in origin is well-ripen pericarp, not seed, the permissible level, 30.0%, is supposed to be simple error range, 3.0%. Conclusions : As a result, I think bills concerning the Zanthoxylum Peel's Purity should be revised to the total number 3.0% or specifically set the level 2.0% of seeds, 1.0% of fruit stalk, twig and so on.

Zanthoxylum Peel is widely used as a common spice for a variety of foods. In the orient, it has also been used as traditional agents for treating diseases such as indigestion. Recently, Zanthoxylum Peel has been reported to have anti-cancer activity, anti-microbial activity, and anti-inflammatory activity. Chemical components are known sanshool compounds and xanthoxylin. In this study, we were carried out to investigate the constituents of inhibiting a drug metabolizing enzyme CYP3A4 from Zanthoxylum Peel. CYP3A4 is known as an enzyme involved in drug metabolism as monooxygenase containing the heme. As a result of experiment, we found that bergapten ($IC_{50}=18.21{\mu}M$) and quercetin ($IC_{50}=17.27{\mu}M$) isolated from EtOAc extract of Zanthoxylum Peel showed remarkable CYP3A4-inhibiting activities. Structures of the isolated active compounds were established by chemical and spectroscopic means.

The aim of this study was to investigate the possible utilization of Zanthoxylum schinifolium as a source of antimicrobial agents. The antimicrobial effects of Zanthoxylum schinifolium extracts were investigated against Acinetobacter baumannii, which is a multi-drug resistant pathogen, and 5 other pathogenic microorganisms. The hexane extract of Zanthoxylum schinifolium was more effective than the ethyl acetate, n-butanol and methanol extracts which were active against Acinetobacter baumannii 25, with minimum inhibitory concentrations(MIC) ranging from 0.8 mg/ml to 1.6 mg/ml. Tetracycline had no effect on Acinetobacter baumanniii. The hexane extract was highly active against Candida albicans IFO 6258, with an MIC of 1.5 mg/ml. In contrast, the ethyl acetate, n-butanol and methanol extracts showed no activity against the 5 pathogenic microorganisms. Furthermore, a combination of hexane extract and ethyl acetate extract was significantly more active against the 5 Acinetobacter baumannii strains than n-butanol and methanol. These results suggest that Zanthoxylum schinifolium extracts have great potential as antimicrobial compounds against multi-drug resistant pathogens, and further studies are warranted.

산초는 우리나라를 비롯한 일본, 중국 등지 에 널리 분포하고 있으며 전통적으로 우리 정서에 친숙한 식미와 향기를 가지는 아시아권의 공통적인 향신료이다. 더불어 우리나라에서는 생선회와 어패류의 소비가 증가함에 따라 Vibrio parahaemolyticus에 의한 식중독발생 억제방안의 확립이 필요한 실정이다. 따라서 본 연구는 독성이 없는 새로운 천연 식품 보존제의 개발을 위하여 식품 및 향신료로서 적용 범위가 광범위한 산초를 대상으로 Vibrio parahaemolyticus에 대한 천연항균제의 적용 가능성을 검토하였다. 산초나무 추출물의 항균작용을 알아보기 위해서 Vibrio parahaemolyticus에 대한 항균력 분석에서 종자를 제외한 성분으로 제조한 산초의 주정추출물이 효과가 가장 우수함을 확인하였으며, 이 추출물의 온도 및 pH에 대한 안정성을 검토한 결과 다양한 범위의 온도, pH에 대해서 매우 안정하다는 것을 알 수 있었다. 또한 GC-MS에 의한 산초 추출물의 분리, 동정 결과에서는 estragole이 항균활성을 나타내는 주성분임을 확인하였다. 이 결과를 바탕으로 우리나라에서 많이 사용되는 산초를 Vibrio parahaemolyticus에 의한 식중독을 줄일 수 있는 항균제로 적용할 수 있음을 확인할 수 있었다. 따라서 식품첨가제 및 포장재, 식품포장 외부 충진 물질, 살균소독제 등의 다양한 형태로의 응용이 가능하리라 생각된다.

The aim of this study was to identify essential oils (EOs) and their concentrations that improved the sensory characteristics of Kochujang by analyzing the effect of the essential oil on the sensory characteristics of Kochujang. EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium, which have an outstanding flavor, were added to Kochujang and the resulting products were subjected to sensory evaluation as a function of storage period. The change in the color of Kochujang by the addition of these EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium was not observed. Kochujang's characteristic flavor was decreased by an increase in the concentrarion of EOs; however, no significant difference was observed when 0.0005% EOs were added relative to the none-additive groups (p<0.05). EOs addition did not affect the hot taste of Kochujang and as the additive quantity increased Kochujang's characteristic taste significantly decreased (p<0.05). After a storage period of 12 weeks, the overall preference of Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum was same as the none-additive groups (p<0.05). Therefore, it is suggested that EOs from Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum can be applied as additives to improve the characteristic taste and flavor of Kochujang and the recommended concentration level is 0.0005%.
