The volatile flavor components of Zanthoxylum pipperitum A.P. DC. produced in Korea and China were isolated using a Clevenger-type apparatus by steam distillation extraction, and analyzed by gas chromatography-mass spectrometry (GC/MS). The yields of oils from Korean and Chinese Z. pipperitum A.P. DC. were 2.0 and 1.2% (w/w), respectively. From the two Z. pipperitum A.P. DC. oils, sixty and fifty-four volatile flavor compounds were tentatively identified, and they constituted 94.78 and 87.34% of the total peak area, respectively. Piperitone(p-menth-1-en-3-one) (13.48%) was the most abundant compound in the Chinese Zanthoxylum pipperitum A.P. DC. oil, followed by $\beta$-phellandrene, sabinene, terpinen-4-ol and linalool (each >5%). Whereas, the most abundant compound in the Korean Zanthoxylum pipperitum A.P. DC. oil was limonene (18.04%), followed by geranyl acetate, cryptone, citronellal, cuminal and phellandral (each >5%).

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.
