๊ณตํ๋ถ,2020. 2. ๊น์ ํ.The purpose of this study was to isolate the flesh and peel of Miyamoto(Citrus unshiu Marcow), Hanlabong(Citrus hybrid Shiranuhi), Redhyang(Citrus hybrid Kanpei), Hwangkeumhyang(Citrus hybrid Beni Madonna), among citrus fruits, one of the most commonly consumed fruits in Korea, and then compare the metabolites with metabolomics, separately. Fruits were analyzed in GC-MS/MS using a derivatization method that improves and allows better separation. Based on the analyzed data, the primary screening was selected using score scatter plot of the Principal Component Analysis (PCA) and ANOVA, which is a statistical tool, and then more precisely using the Partial Least Squares Discriminant Analysis (PLS-DA). The substance which specified the sample of each citrus fruits were identified. For Miyamoto, n-acetylneuraminic acid, glucono-1,5-lactone and inositol in flesh, In addition methionine and tyramine in the skin were identified as specific substances. In case of Hallabong, gluconic acid, 2-deoxy-glucose and 4-hydroxyphenylpyruvic acid in flesh, o-acetylserine, pentadecanoic acid, hippuric acid in peel, tyramine, octopamine and coniferyl alcohol in the flesh of Hwangkeumhyang, and xamic acid, putrescine and xanthosinein the peel were identified as the specific substances. According to Redhyang adenine, 2-amino-octanoic acid and valproic acid were in flesh, cystathionine, spermidine and thymidine in the skin were identified.๋ณธ ์ฐ๊ตฌ๋ ํ๊ตญ์์ ๋ง์ด ์๋น๋๋ ๊ณผ์ผ ์ฆ ํ๋์ธ ๊ฐ๊ทค๋ฅ ์ค ๋ฏธ์ผ๋ชจํ ๊ทค, ํฉ๊ธํฅ, ํ๋ผ๋ด, ๋ ๋ํฅ์ ๊ณผ์ก๊ณผ ๊ป์ง์ ๋ถ๋ฆฌํ ํ, ๋์ฌ์ฒดํ (metabolomics) ์ ์ ์ฉํ์ฌ ๊ฐ๊ฐ ์์ฒด ๋์ฌ๋ฌผ์ง์ ๋น๊ต ํ์์ผ๋ฉฐ, ๋ถ์ ๊ฐ๋๋ฅผ ํฅ์ ์์ผ์ฃผ๊ณ , ๋ ๋์ ๋ถ๋ฆฌ๋ฅผ ํ ์ ์๊ฒ ํด์ฃผ๋ ์ ๋์ฒดํ ๋ฐฉ๋ฒ์ ์ด์ฉํ์ฌ GC-MS/MS ์์ ๋ถ์ํ์๋ค. ๋ถ์ํ ์๋ฃ๋ฅผ ๋ฐํ์ผ๋ก ํต๊ณ ๋๊ตฌ์ธ Principal Component Analysis (PCA) ์ score scatter plot ๊ณผ ANOVA๋ฅผ ์ฌ์ฉํ์ฌ 1์ฐจ ์ ์ผ๋ก ์ ๋ณํด ์ค ํ, Partial least squares Discriminant Analysis (PLS-DA) ๋ฅผ ์ด์ฉํ์ฌ ๋ณด๋ค ์ธ๋ฐํ๊ฒ ๊ฐ๊ทค๋ฅ ๊ฐ๊ฐ์ ์๋ฃ๋ฅผ ํน์ ํ๋ ๋ฌผ์ง์ ํ์ธํ์๋ค. ๋ฏธ์ผ๋ชจํ ๊ทค์ ๊ฒฝ์ฐ ๊ณผ์ก์์ n-acetylneuraminic acid, glucono-1,5-lactone ๊ทธ๋ฆฌ๊ณ inositol, ๊ณผํผ์ ๊ฒฝ์ฐ methionine๊ณผ tyramine๋ค์ด ์ด ์๋ฃ๋ฅผ ํน์ ํ๋ ๋ฌผ์ง๋ก ๋ํ๋ฌ๊ณ . ํ๋ผ๋ด์ ๊ฒฝ์ฐ ๊ณผ์ก์์ gluconic acid, 2-deoxy-glucose ๊ทธ๋ฆฌ๊ณ 4-hydroxy-phenylpyruvic acid์ด ๊ณผํผ์์ o-acetylserine, pentadecanoic acid, hippuric acid ์ผ๋ก ๋ํ๋ฌ์ผ๋ฉฐ, ํฉ๊ธํฅ์ ๊ฒฝ์ฐ ๊ณผ์ก์์ tyramine, octopamine ๊ทธ๋ฆฌ๊ณ coniferyl alcohol์ด, ๊ณผํผ์ ๊ฒฝ์ฐ xamic acid, putrescine, xanthosine๋ฑ์ด ๋ค๋ฅธ ์๋ฃ์ ๋นํด ๋ง์ด ๋ํ๋ฌ๋ค. ๋ ๋ํฅ์ ๊ฒฝ์ฐ ๊ณผ์ก์์ adenine, 2-aminooctanoic acid and valproic acid, ๊ณผํผ์์ cystathionine, spermidine ๊ทธ๋ฆฌ๊ณ thymidine์ด ์๋ฃ๋ฅผ ํน์ ํ๋ ๋ฌผ์ง๋ก ๋ํ๋ฌ๋ค.1.Introduction 2
