The fruits of Zanthoxylum piperitum are known as having various physiology vitality, and the abstraction ingredient of the pericarp is also known as having strong antibiotic activities against various bacteria. Therefore, this study was carried out to estimate the effect of physiology vitality when the abstraction ingredient of Z. piperitum was added in soy sauce(Chopi-kanjang) and soybean paste(Chopi-doenjang). For the antibiotic activity against the pathogens of sitotoxism such as Staphylococcus aureus, Salmonella typhimurium, Vibrio parahemolyticus, Escherichia coli 0157:H7, the extracts of the Chopi-kanjang was added 1%, 2%, 4% pericarp of Z. piperitum in the manufacturing process of soy source. According to the results, the growth of E. coli 0157:H7 and V. parahemolyticus were respectively inhibited as 70% and 50% by the Chopi-kanjang added 2% of the ingredient. For the antibiotic effects of the aforementioned Chopi-kanjang against Sal. typhimurium and Sta. aureus, the growth of those pathogens was also inhibited between 40% and 60% according to the manufacturing period of Chopi-kanjang. It was confirmed that the antibiotic activity using the mixture of the abstraction ingredient and Chopi-doenjang was lower than those of Chopi-kanjang. In order to estimate the anticancer activity using by caspase-3 activity, the mixture of the abstraction ingredient of the pericarp of Z. piperitum and Chopi-kanjang was treated to leukemia cells. According to the results, the activities of caspase-3 using the mixture added 1%, 2% and 4% of the abstraction ingredient were respectively increased as much as 4, 12, 15 times comparing with the control which was treated with the soy source only. It could be that the mixture of the abstraction ingredient of the pericarp of Z. piperitum and soy source induced apoptosis, and the mixture of the abstraction ingredient and soybean paste had no effect on the activity of caspase-3. In order to find out the death of the aforementioned cells caused by necrosis or apoptosis, DNA fragmentation in the cell was examined. U-937 cells showed apoptotic DNA fragmentation in the incubation with Chopi-kanjang extract.

The antioxidative and antimicrobial activity were carried on the Chopi(Zanthoxylum pipperitum) extracts by six kinds of solvents in order to find out new natural food additives. Six solvents were used methanol(MeOH), n-hexan(hexane), chloroform$(CHCl_3)$, ethylacetate(EtOAc), buthanol(BuOH), and water(water) and methanol extract(MEex), hexan extract(HEex), chloroform extract(CHex), ethylacetate extract(EAex), and buthanol extract(BUex), water extract(WAex). The antioxdative activities of them extracts were determined by peroxide value(POV), conjugated diene value(CDV) of corn germ oil storaged for 30 days at $60{\pm}2^{\circ}C$. These extracts were added as 0.02, 0.1, 0.2% of each extracts and compared with ${\alpha}-tocopherol$, and BHT. The antioxidative activities of 0.02% extract were as follows in decreasing order BUex > WAex, BHT, MEex > HEex, EAex, CHex > TOC, and control. While, BUex and CHex among these extracts were shown to be had antimicrobial effects on the microorganism such as Escheria coli, Salmonella typhimurium, Psedomonas aeruginosa, Staphylococcus aureus, and Listeria monocytogenes. Finally to find out the preference of chopi we had made Yugwanzageon (a kind of shallow fried meat ball)by adding chopi powder. The result were similar to control(not added chopi powder) in case of 0.1% chopi adding Yugwanzageon.(p<0.05) Therefore it was thought to be possible that chopi powder was used Yugwanzageon preperation.

Zanthoxylum piperitum and Z. schinifolium have been utilized not only as food stuffs, but also as medicinal plants in Korea. In this study, lipids, sugar, amino acids and other components of Zanthoxylum piperitum and Z. schinifolium peels and seeds were analyzed by HPLC and GLC. Four samples contained common fatty acids such as linoleic, linolenic, palmitic, oleic and stearic acid. The contents of unsaturated fatty acids were 87.1% and 64.8% in Z. schinifolium peels and seeds, 73.6% and 62.9% in Z. piperitum peels and seeds, respectively. Z. schinifolium peels contained only beta-sitosterol, whereas other three samples contained campesterol, stigmasterol and beta-sitosterol. In case of free amino acids, peels of both species showed higher contents of acids than seeds of both species. Glutamic acid, aspartic acid, arginine, valine, and leucine were found in all four samples. Essential oils consisted of limonene (30.1-66.8%), beta-phellandrene (4.8-13.3%), citronellal (1.5-22%) and cineol (1.6-3.9%). It is worthwhile to note that the content of citronellal in Z. schinifolium seeds was higher than that of the others.

Antimicrobial activity of Zanthoxylum piperitum was investigated against Streptococcus mutans that causes dental caries. Although the methylene chloride extract of seeds exhibited higher antimicrobial activity than other organic solvent extracts, including methanol, ethyl acetate, and hexane extracts of pericarps or seeds of Z. piperitum, essential oils prepared from both seeds and pericarps possessed more potent inhibitory activity than the methylene chloride extract of seeds. The minimal inhibitory concentrations (MICs) of the essential oils of seeds and pericarps were 0.3 mg/ml and 4.0 mg/ml against S. mutans, respectively. When the seed essential oil was further separated into seven fractions (CS-SD-A${\sim}$CS-SD-G) by thin layer chromatography (TLC), all fractions exhibited lower antimicrobial activity than the essential oil. To understand the antimicrobial ingredients of Z. piperitum, seeds the gas chromatography-mass spectrometry (GC-MS) data of the methylene chloride extract of seeds was compared with those of the seed essential oil (CS-SD). Whereas the methylene chloride extract of seeds contained carvacrol (0.24%), ${\beta}$-caryophyllene (1.72%), and ${\alpha}$-humulene (0.88%), which were previously known to inhibit growth of S. mutans, the seed essential oil contained sabinene (1.57%), linalool (1.55%), citronellal (13.67%), terpinene-4-ol (0.45%), citronellol (3.69%), geraniol (0.9%), linalyl acetate (1.35%), ${\beta}$-caryophyllene (1.35%), ${\alpha}$-humulene (0.78%), and ${\delta}$-cadinene (0.67%) in this regard. These results indicate that Z. piperitum seeds possess various inhibitory substances against S. mutans, and an effective method to isolate the active ingredients from the seeds is to prepare the essential oil. These results also suggest that the essential oil of Z. piperitium seeds may be applicable to preventing dental caries.

The present study was conducted to investigate the effects of components obtained from Zanthoxylum schinifolium and Zanthoxylum piperitum on rancidity and quality of Kwamegi (semi-dried Pacific saury, Coloabis saira). Ethanol extract (ZS) of Zanthoxylum schinifolium leaves or the essential oil (ZP) obtained from pericarp of Zanthoxylum piperitum in 1 or 20% ethanol solution was sprayed to the Pacific saury before Kwamegi preparation at its final concentrations of 0.125~2 ppm in the Kwamegi. The prepared Kwamegi was vacuum packed with multi-layered film (polyethylene/polyamide/EVOH/polyethylene, thickness 80 μm) and kept at -20${^{\circ}C}$ until use. After opening the package Kwamegi was stored at 4${^{\circ}C}$ for 1, 3 and 7 days during which rancidity tests and sensory evaluation were carried out. Acid, peroxide, and thiobarbituric acid (TBA) values increased with storage time but reduced significantly by the addition of ZS at the concentrations of ≥G0.125 ppm and ZP≥F0.25 ppm. The effects of ZS and ZP were dose-dependent and more pronounced as storage time prolonged. The ZS and ZP also reduced dimethyamine and trimethyamine (TMA) contents which were increased with time, while they prevented the decrease of trimethyamine oxide. The ZS at the concentration of ≥G0.25 ppm and the ZP at >0.5 ppm were needed to maintain TMA less than 4.5 mg/100 g for 3 day storage at 4${^{\circ}C}$. Sensory evaluation of the Kwamegi exhibited a slightly higher preference with the ZS and ZP treated ones at the level of 0.25~0.5 ppm. It is concluded that very low amounts of ZS and ZP are effective in suppression of rancidity of Kwamegi and could be utilized for its quality management.

This study focused on the in vitro investigation of antioxidant and anti-diabetic activities, along with neuroprotection against high glucose-induced cytotoxicity, in order to evaluate the physiological effects of Zanthoxylum piperitum and Zanthoxylum schinifolium. The highest total phenolic content was measured in the 40% ethanolic extracts of Zanthoxylum piperitum (EZP) and Zanthoxylum schinifolium (EZS). The in vitro EZP antioxidant activity showed a relatively higher ABTS/DPPH radical scavenging activity and malondialdehyde inhibitory effect than that of EZS. The EZP inhibited carbohydrate hydrolysis (α-glucosidase and α-amylase) more efficiently than EZS in anti-diabetic tests. However, EZS showed a more efficient inhibition of advanced glycation end-products formation than EZP. In addition, both EZP and EZS effectively protected human-derived neuronal cells from high glucose-induced cytotoxicity. Finally, the physiological compounds were analyzed using UPLC IMS-QTOF/MS^E, and the main EZP (quercetin-3-O-glucoside and 3-caffeoylquinic acid) and EZS (5-caffeoylquinic acid) compounds were identified as phenolic compounds.
