  • Zanthoxylum schinifolium and Zanthoxylum piperitum A.P. DC. belong to the Rutaceae family and are perennial, aromatic, and medicinal herbaceous plants. In this study, their aroma compounds were isolated by steam distillation extraction using a Clevenger-type apparatus, and then further analyzed by gas chromatography (GC) and gas chromatograph/mass spectrometry (GC/MS). The yields of the essential oils from Z. schinifolium and Z. piperitum AP. DC. were 2.5 and 2.0%(w/w), respectively, and the color of their oils was quite similar, a pale yellow. From the distilled oil of Z. schinifolium, 60 volatile compounds which make up 87.24% of the total composition were tentatively identified, with monoterpenes predominating. $\beta$-Phellandrene (22.54%), citronellal (16.48%), and geranyl acetate (11.39%) were the predominantly abundant components of Z. schinifolium. In the essential oil of Z. piperitum AP. DC., 60 volatile flavor components constituted 94.78% of the total peak area were tentatively characterized. Limonene (18.04%), geranyl acetate (15.33%), and cryptone (8.52%) were the major volatile flavor compounds of Z. piperitum A.P. DC.

  • 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.

  • Seasonal variations in the profile and concentrations of essential oil in Zanthoxylum piperitum were investigated by gas chromatography-mass spectrometry. Seasonal changes in the percentages of the main constituents of the essential oil of both leaves and fruits from Z. piperitum varied. Variations in essential oil yield and the amount of monoterpenes and sesquiterpenes in leaves and fruits at different developmental stages were significant. The characteristic content of essential oil in leaves was determined mainly due to the content of monoterpenes, and that in fruits was determined largely due to the sesquiterpenes. Twenty-nine compounds in the oil from Z. piperitum leaves were detected; the major compounds were ${\beta}$-phellandrene (26.90%), citronella (15.32%), ${\beta}$-myrcene (3.24%), ${\alpha}$-pinene (2.79%), trans-caryophyllene (2.66%), and fanesyl acetate (2.30%). The highest yield of oil (43.89%) in Z. piperitum leaves was obtained in May but decreased gradually beginning in June. The yield of essential oil from Z. piperitum leaves during early periods was higher than that during later periods and usually decreased from early maturation stages to subsequent stages. However, in contrast to leaves, the oil yield in Z. piperitum fruit increased in June, and oil yield later in the season was higher than that earlier in the season. These results indicate that the essential oil produced from Z. piperitum leaves at the early developmental stages was stored in leaves, and might be transferred to fruit at the final developmental stages.

  • A protocol is described for rapid multiplication of Zanthoxylum piperitum DC. (Rutaceae), an important aromatic and medicinal plant, through shoot-tip explant cultures. Murashige and Skoog (MS) medium supplemented with various concentrations of N-6-benzyladenine (BA), N-6-benzylaminopurine (BAP) and thidiazuron (TDZ), in single or in combination with ${\alpha}-naphthaleneacetic$ acid (NAA), was used to determine the rate of shoot proliferation. N-6-benzyladenine (BA) used at 0.5mg/l, was the most effective in initiating multiple shoot proliferation at the rate of 23 microshoots per shoot-tip explants after 40 days of culture. Shoot multiplication increased 1.2-fold in each successive subculture. Induction of rooting (98%) was achieved by transferring the shoots to the same basal medium containing 2 mg/l indole-3-butyric acid (IBA). Plantlets went through a hardening phase in a controlled growth chamber, prior to in vivo transfer. These results represented that possible application for the mass production of plantlets through in vitro culture system of Zanthoxylum piperitum DC.

  • In order to evaluate the antimicrobial function of natural herb extracts as antimicrobial agent or packaging material for the preservation of foods and greenhouse produce, the water extract of chopi (Zanthoxylum piperitum DC.) was prepared and its antimicobial activity was determined. In the paper disk test its antimicrobial activity was increased in proportion to its concentraion. The growth of microorganisms was completely inhibited above 500ppm of its concentration. It showed wide spectrum of thermal(40 to 180oC) and pH(4 to 10) stabilities. In the electronic microscopic observation(TEM and SEM) of microbial morphological change it showed to decrease the activation of physiological enzymes and to lose the function of cell membranes. Even in the activation test of galactosidase, it seemed to weaken the osmotic function of cell membranes remarkably in comparison with chloroform and its activation corresponded to 40~50% of toluene. Zanthoxylum piperitum DC. extract seemed to be an excellent antimicrobial for the inhibition of food borne microorganisms as well as the pre servation of greenhouse produces.

  • 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%.

  • This study was carried out to investigate the potential use of Zanthoxylum schinifolium and Zanthoxylum piperitum A.P. DC. as a source of antimicrobial agents against food borne pathogens. Essential oils of Z. schinifolium and Z. piperitum A.P. DC. were collected by steam distillation and analyzed by GC-MS. The antimicrobial activity of the essential oils was examined using the agar diffusion and micro-dilution assays. The effectiveness of Z. schinifolium essential oil was greater against Bacillus cereus, Staphylococcus aureus, and Vibrio parahaemolyticus than other pathogens, and the minimal inhibitory concentration (MIC) values were 1.25, 2.5, and 1.25, 2.5, and $1.25\;{\mu}g/mL$, respectively. Z. piperitum A.P. DC. essential oil was the most effective against all pathogens tested except for Escherichia coli O157:H7, and the MIC values against B. cereus, Salmonella choleraesuis, and V. parahaemolyticus were 1.25, 2.5, and $1.25\;{\mu}g/mL$, respectively. Limonene, the major component of Z. piperitum A.P. DC. essential oils, had the highest inhibitory activity toward V. parahaemolyticus with a MIC value of $0.15\;{\mu}g/mL$. Meanwhile, citronellal and geranyl acetate, major components of both essential oils, displayed antibacterial activity against only B. cereus with MIC values of 1.25 and $5\;{\mu}g/mL$, respectively. Therefore, these essential oils could be useful as antimicrobial agents against foodborne pathogens.
